Chapter 15. IngressController [operator.openshift.io/v1] Description IngressController describes a managed ingress controller for the cluster. The controller can service OpenShift Route and Kubernetes Ingress resources. When an IngressController is created, a new ingress controller deployment is created to allow external traffic to reach the services that expose Ingress or Route resources. Updating this resource may lead to disruption for public facing network connections as a new ingress controller revision may be rolled out. https://kubernetes.io/docs/concepts/services-networking/ingress-controllers Whenever possible, sensible defaults for the platform are used. See each field for more details. Compatibility level 1: Stable within a major release for a minimum of 12 months or 3 minor releases (whichever is longer). Type object 15.1. Specification Property Type Description apiVersion string APIVersion defines the versioned schema of this representation of an object. Servers should convert recognized schemas to the latest internal value, and may reject unrecognized values. More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#resources kind string Kind is a string value representing the REST resource this object represents. Servers may infer this from the endpoint the client submits requests to. Cannot be updated. In CamelCase. More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#types-kinds metadata ObjectMeta Standard object's metadata. More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#metadata spec object spec is the specification of the desired behavior of the IngressController. status object status is the most recently observed status of the IngressController. 15.1.1. .spec Description spec is the specification of the desired behavior of the IngressController. Type object Property Type Description clientTLS object clientTLS specifies settings for requesting and verifying client certificates, which can be used to enable mutual TLS for edge-terminated and reencrypt routes. defaultCertificate object defaultCertificate is a reference to a secret containing the default certificate served by the ingress controller. When Routes don't specify their own certificate, defaultCertificate is used. The secret must contain the following keys and data: tls.crt: certificate file contents tls.key: key file contents If unset, a wildcard certificate is automatically generated and used. The certificate is valid for the ingress controller domain (and subdomains) and the generated certificate's CA will be automatically integrated with the cluster's trust store. If a wildcard certificate is used and shared by multiple HTTP/2 enabled routes (which implies ALPN) then clients (i.e., notably browsers) are at liberty to reuse open connections. This means a client can reuse a connection to another route and that is likely to fail. This behaviour is generally known as connection coalescing. The in-use certificate (whether generated or user-specified) will be automatically integrated with OpenShift's built-in OAuth server. domain string domain is a DNS name serviced by the ingress controller and is used to configure multiple features: * For the LoadBalancerService endpoint publishing strategy, domain is used to configure DNS records. See endpointPublishingStrategy. * When using a generated default certificate, the certificate will be valid for domain and its subdomains. See defaultCertificate. * The value is published to individual Route statuses so that end-users know where to target external DNS records. domain must be unique among all IngressControllers, and cannot be updated. If empty, defaults to ingress.config.openshift.io/cluster .spec.domain. endpointPublishingStrategy object endpointPublishingStrategy is used to publish the ingress controller endpoints to other networks, enable load balancer integrations, etc. If unset, the default is based on infrastructure.config.openshift.io/cluster .status.platform: AWS: LoadBalancerService (with External scope) Azure: LoadBalancerService (with External scope) GCP: LoadBalancerService (with External scope) IBMCloud: LoadBalancerService (with External scope) AlibabaCloud: LoadBalancerService (with External scope) Libvirt: HostNetwork Any other platform types (including None) default to HostNetwork. endpointPublishingStrategy cannot be updated. httpCompression object httpCompression defines a policy for HTTP traffic compression. By default, there is no HTTP compression. httpEmptyRequestsPolicy string httpEmptyRequestsPolicy describes how HTTP connections should be handled if the connection times out before a request is received. Allowed values for this field are "Respond" and "Ignore". If the field is set to "Respond", the ingress controller sends an HTTP 400 or 408 response, logs the connection (if access logging is enabled), and counts the connection in the appropriate metrics. If the field is set to "Ignore", the ingress controller closes the connection without sending a response, logging the connection, or incrementing metrics. The default value is "Respond". Typically, these connections come from load balancers' health probes or Web browsers' speculative connections ("preconnect") and can be safely ignored. However, these requests may also be caused by network errors, and so setting this field to "Ignore" may impede detection and diagnosis of problems. In addition, these requests may be caused by port scans, in which case logging empty requests may aid in detecting intrusion attempts. httpErrorCodePages object httpErrorCodePages specifies a configmap with custom error pages. The administrator must create this configmap in the openshift-config namespace. This configmap should have keys in the format "error-page-<error code>.http", where <error code> is an HTTP error code. For example, "error-page-503.http" defines an error page for HTTP 503 responses. Currently only error pages for 503 and 404 responses can be customized. Each value in the configmap should be the full response, including HTTP headers. Eg- https://raw.githubusercontent.com/openshift/router/fadab45747a9b30cc3f0a4b41ad2871f95827a93/images/router/haproxy/conf/error-page-503.http If this field is empty, the ingress controller uses the default error pages. httpHeaders object httpHeaders defines policy for HTTP headers. If this field is empty, the default values are used. logging object logging defines parameters for what should be logged where. If this field is empty, operational logs are enabled but access logs are disabled. namespaceSelector object namespaceSelector is used to filter the set of namespaces serviced by the ingress controller. This is useful for implementing shards. If unset, the default is no filtering. nodePlacement object nodePlacement enables explicit control over the scheduling of the ingress controller. If unset, defaults are used. See NodePlacement for more details. replicas integer replicas is the desired number of ingress controller replicas. If unset, the default depends on the value of the defaultPlacement field in the cluster config.openshift.io/v1/ingresses status. The value of replicas is set based on the value of a chosen field in the Infrastructure CR. If defaultPlacement is set to ControlPlane, the chosen field will be controlPlaneTopology. If it is set to Workers the chosen field will be infrastructureTopology. Replicas will then be set to 1 or 2 based whether the chosen field's value is SingleReplica or HighlyAvailable, respectively. These defaults are subject to change. routeAdmission object routeAdmission defines a policy for handling new route claims (for example, to allow or deny claims across namespaces). If empty, defaults will be applied. See specific routeAdmission fields for details about their defaults. routeSelector object routeSelector is used to filter the set of Routes serviced by the ingress controller. This is useful for implementing shards. If unset, the default is no filtering. tlsSecurityProfile object tlsSecurityProfile specifies settings for TLS connections for ingresscontrollers. If unset, the default is based on the apiservers.config.openshift.io/cluster resource. Note that when using the Old, Intermediate, and Modern profile types, the effective profile configuration is subject to change between releases. For example, given a specification to use the Intermediate profile deployed on release X.Y.Z, an upgrade to release X.Y.Z+1 may cause a new profile configuration to be applied to the ingress controller, resulting in a rollout. tuningOptions object tuningOptions defines parameters for adjusting the performance of ingress controller pods. All fields are optional and will use their respective defaults if not set. See specific tuningOptions fields for more details. Setting fields within tuningOptions is generally not recommended. The default values are suitable for most configurations. unsupportedConfigOverrides `` unsupportedConfigOverrides allows specifying unsupported configuration options. Its use is unsupported. 15.1.2. .spec.clientTLS Description clientTLS specifies settings for requesting and verifying client certificates, which can be used to enable mutual TLS for edge-terminated and reencrypt routes. Type object Required clientCA clientCertificatePolicy Property Type Description allowedSubjectPatterns array (string) allowedSubjectPatterns specifies a list of regular expressions that should be matched against the distinguished name on a valid client certificate to filter requests. The regular expressions must use PCRE syntax. If this list is empty, no filtering is performed. If the list is nonempty, then at least one pattern must match a client certificate's distinguished name or else the ingress controller rejects the certificate and denies the connection. clientCA object clientCA specifies a configmap containing the PEM-encoded CA certificate bundle that should be used to verify a client's certificate. The administrator must create this configmap in the openshift-config namespace. clientCertificatePolicy string clientCertificatePolicy specifies whether the ingress controller requires clients to provide certificates. This field accepts the values "Required" or "Optional". Note that the ingress controller only checks client certificates for edge-terminated and reencrypt TLS routes; it cannot check certificates for cleartext HTTP or passthrough TLS routes. 15.1.3. .spec.clientTLS.clientCA Description clientCA specifies a configmap containing the PEM-encoded CA certificate bundle that should be used to verify a client's certificate. The administrator must create this configmap in the openshift-config namespace. Type object Required name Property Type Description name string name is the metadata.name of the referenced config map 15.1.4. .spec.defaultCertificate Description defaultCertificate is a reference to a secret containing the default certificate served by the ingress controller. When Routes don't specify their own certificate, defaultCertificate is used. The secret must contain the following keys and data: tls.crt: certificate file contents tls.key: key file contents If unset, a wildcard certificate is automatically generated and used. The certificate is valid for the ingress controller domain (and subdomains) and the generated certificate's CA will be automatically integrated with the cluster's trust store. If a wildcard certificate is used and shared by multiple HTTP/2 enabled routes (which implies ALPN) then clients (i.e., notably browsers) are at liberty to reuse open connections. This means a client can reuse a connection to another route and that is likely to fail. This behaviour is generally known as connection coalescing. The in-use certificate (whether generated or user-specified) will be automatically integrated with OpenShift's built-in OAuth server. Type object Property Type Description name string Name of the referent. More info: https://kubernetes.io/docs/concepts/overview/working-with-objects/names/#names TODO: Add other useful fields. apiVersion, kind, uid? 15.1.5. .spec.endpointPublishingStrategy Description endpointPublishingStrategy is used to publish the ingress controller endpoints to other networks, enable load balancer integrations, etc. If unset, the default is based on infrastructure.config.openshift.io/cluster .status.platform: AWS: LoadBalancerService (with External scope) Azure: LoadBalancerService (with External scope) GCP: LoadBalancerService (with External scope) IBMCloud: LoadBalancerService (with External scope) AlibabaCloud: LoadBalancerService (with External scope) Libvirt: HostNetwork Any other platform types (including None) default to HostNetwork. endpointPublishingStrategy cannot be updated. Type object Required type Property Type Description hostNetwork object hostNetwork holds parameters for the HostNetwork endpoint publishing strategy. Present only if type is HostNetwork. loadBalancer object loadBalancer holds parameters for the load balancer. Present only if type is LoadBalancerService. nodePort object nodePort holds parameters for the NodePortService endpoint publishing strategy. Present only if type is NodePortService. private object private holds parameters for the Private endpoint publishing strategy. Present only if type is Private. type string type is the publishing strategy to use. Valid values are: * LoadBalancerService Publishes the ingress controller using a Kubernetes LoadBalancer Service. In this configuration, the ingress controller deployment uses container networking. A LoadBalancer Service is created to publish the deployment. See: https://kubernetes.io/docs/concepts/services-networking/service/#loadbalancer If domain is set, a wildcard DNS record will be managed to point at the LoadBalancer Service's external name. DNS records are managed only in DNS zones defined by dns.config.openshift.io/cluster .spec.publicZone and .spec.privateZone. Wildcard DNS management is currently supported only on the AWS, Azure, and GCP platforms. * HostNetwork Publishes the ingress controller on node ports where the ingress controller is deployed. In this configuration, the ingress controller deployment uses host networking, bound to node ports 80 and 443. The user is responsible for configuring an external load balancer to publish the ingress controller via the node ports. * Private Does not publish the ingress controller. In this configuration, the ingress controller deployment uses container networking, and is not explicitly published. The user must manually publish the ingress controller. * NodePortService Publishes the ingress controller using a Kubernetes NodePort Service. In this configuration, the ingress controller deployment uses container networking. A NodePort Service is created to publish the deployment. The specific node ports are dynamically allocated by OpenShift; however, to support static port allocations, user changes to the node port field of the managed NodePort Service will preserved. 15.1.6. .spec.endpointPublishingStrategy.hostNetwork Description hostNetwork holds parameters for the HostNetwork endpoint publishing strategy. Present only if type is HostNetwork. Type object Property Type Description httpPort integer httpPort is the port on the host which should be used to listen for HTTP requests. This field should be set when port 80 is already in use. The value should not coincide with the NodePort range of the cluster. When the value is 0 or is not specified it defaults to 80. httpsPort integer httpsPort is the port on the host which should be used to listen for HTTPS requests. This field should be set when port 443 is already in use. The value should not coincide with the NodePort range of the cluster. When the value is 0 or is not specified it defaults to 443. protocol string protocol specifies whether the IngressController expects incoming connections to use plain TCP or whether the IngressController expects PROXY protocol. PROXY protocol can be used with load balancers that support it to communicate the source addresses of client connections when forwarding those connections to the IngressController. Using PROXY protocol enables the IngressController to report those source addresses instead of reporting the load balancer's address in HTTP headers and logs. Note that enabling PROXY protocol on the IngressController will cause connections to fail if you are not using a load balancer that uses PROXY protocol to forward connections to the IngressController. See http://www.haproxy.org/download/2.2/doc/proxy-protocol.txt for information about PROXY protocol. The following values are valid for this field: * The empty string. * "TCP". * "PROXY". The empty string specifies the default, which is TCP without PROXY protocol. Note that the default is subject to change. statsPort integer statsPort is the port on the host where the stats from the router are published. The value should not coincide with the NodePort range of the cluster. If an external load balancer is configured to forward connections to this IngressController, the load balancer should use this port for health checks. The load balancer can send HTTP probes on this port on a given node, with the path /healthz/ready to determine if the ingress controller is ready to receive traffic on the node. For proper operation the load balancer must not forward traffic to a node until the health check reports ready. The load balancer should also stop forwarding requests within a maximum of 45 seconds after /healthz/ready starts reporting not-ready. Probing every 5 to 10 seconds, with a 5-second timeout and with a threshold of two successful or failed requests to become healthy or unhealthy respectively, are well-tested values. When the value is 0 or is not specified it defaults to 1936. 15.1.7. .spec.endpointPublishingStrategy.loadBalancer Description loadBalancer holds parameters for the load balancer. Present only if type is LoadBalancerService. Type object Required dnsManagementPolicy scope Property Type Description allowedSourceRanges `` allowedSourceRanges specifies an allowlist of IP address ranges to which access to the load balancer should be restricted. Each range must be specified using CIDR notation (e.g. "10.0.0.0/8" or "fd00::/8"). If no range is specified, "0.0.0.0/0" for IPv4 and "::/0" for IPv6 are used by default, which allows all source addresses. To facilitate migration from earlier versions of OpenShift that did not have the allowedSourceRanges field, you may set the service.beta.kubernetes.io/load-balancer-source-ranges annotation on the "router-<ingresscontroller name>" service in the "openshift-ingress" namespace, and this annotation will take effect if allowedSourceRanges is empty on OpenShift 4.12. dnsManagementPolicy string dnsManagementPolicy indicates if the lifecycle of the wildcard DNS record associated with the load balancer service will be managed by the ingress operator. It defaults to Managed. Valid values are: Managed and Unmanaged. providerParameters object providerParameters holds desired load balancer information specific to the underlying infrastructure provider. If empty, defaults will be applied. See specific providerParameters fields for details about their defaults. scope string scope indicates the scope at which the load balancer is exposed. Possible values are "External" and "Internal". 15.1.8. .spec.endpointPublishingStrategy.loadBalancer.providerParameters Description providerParameters holds desired load balancer information specific to the underlying infrastructure provider. If empty, defaults will be applied. See specific providerParameters fields for details about their defaults. Type object Required type Property Type Description aws object aws provides configuration settings that are specific to AWS load balancers. If empty, defaults will be applied. See specific aws fields for details about their defaults. gcp object gcp provides configuration settings that are specific to GCP load balancers. If empty, defaults will be applied. See specific gcp fields for details about their defaults. ibm object ibm provides configuration settings that are specific to IBM Cloud load balancers. If empty, defaults will be applied. See specific ibm fields for details about their defaults. type string type is the underlying infrastructure provider for the load balancer. Allowed values are "AWS", "Azure", "BareMetal", "GCP", "IBM", "Nutanix", "OpenStack", and "VSphere". 15.1.9. .spec.endpointPublishingStrategy.loadBalancer.providerParameters.aws Description aws provides configuration settings that are specific to AWS load balancers. If empty, defaults will be applied. See specific aws fields for details about their defaults. Type object Required type Property Type Description classicLoadBalancer object classicLoadBalancerParameters holds configuration parameters for an AWS classic load balancer. Present only if type is Classic. networkLoadBalancer object networkLoadBalancerParameters holds configuration parameters for an AWS network load balancer. Present only if type is NLB. type string type is the type of AWS load balancer to instantiate for an ingresscontroller. Valid values are: * "Classic": A Classic Load Balancer that makes routing decisions at either the transport layer (TCP/SSL) or the application layer (HTTP/HTTPS). See the following for additional details: https://docs.aws.amazon.com/AmazonECS/latest/developerguide/load-balancer-types.html#clb * "NLB": A Network Load Balancer that makes routing decisions at the transport layer (TCP/SSL). See the following for additional details: https://docs.aws.amazon.com/AmazonECS/latest/developerguide/load-balancer-types.html#nlb 15.1.10. .spec.endpointPublishingStrategy.loadBalancer.providerParameters.aws.classicLoadBalancer Description classicLoadBalancerParameters holds configuration parameters for an AWS classic load balancer. Present only if type is Classic. Type object Property Type Description connectionIdleTimeout string connectionIdleTimeout specifies the maximum time period that a connection may be idle before the load balancer closes the connection. The value must be parseable as a time duration value; see https://pkg.go.dev/time#ParseDuration . A nil or zero value means no opinion, in which case a default value is used. The default value for this field is 60s. This default is subject to change. 15.1.11. .spec.endpointPublishingStrategy.loadBalancer.providerParameters.aws.networkLoadBalancer Description networkLoadBalancerParameters holds configuration parameters for an AWS network load balancer. Present only if type is NLB. Type object 15.1.12. .spec.endpointPublishingStrategy.loadBalancer.providerParameters.gcp Description gcp provides configuration settings that are specific to GCP load balancers. If empty, defaults will be applied. See specific gcp fields for details about their defaults. Type object Property Type Description clientAccess string clientAccess describes how client access is restricted for internal load balancers. Valid values are: * "Global": Specifying an internal load balancer with Global client access allows clients from any region within the VPC to communicate with the load balancer. https://cloud.google.com/kubernetes-engine/docs/how-to/internal-load-balancing#global_access * "Local": Specifying an internal load balancer with Local client access means only clients within the same region (and VPC) as the GCP load balancer can communicate with the load balancer. Note that this is the default behavior. https://cloud.google.com/load-balancing/docs/internal#client_access 15.1.13. .spec.endpointPublishingStrategy.loadBalancer.providerParameters.ibm Description ibm provides configuration settings that are specific to IBM Cloud load balancers. If empty, defaults will be applied. See specific ibm fields for details about their defaults. Type object Property Type Description protocol string protocol specifies whether the load balancer uses PROXY protocol to forward connections to the IngressController. See "service.kubernetes.io/ibm-load-balancer-cloud-provider-enable-features: "proxy-protocol"" at https://cloud.ibm.com/docs/containers?topic=containers-vpc-lbaas PROXY protocol can be used with load balancers that support it to communicate the source addresses of client connections when forwarding those connections to the IngressController. Using PROXY protocol enables the IngressController to report those source addresses instead of reporting the load balancer's address in HTTP headers and logs. Note that enabling PROXY protocol on the IngressController will cause connections to fail if you are not using a load balancer that uses PROXY protocol to forward connections to the IngressController. See http://www.haproxy.org/download/2.2/doc/proxy-protocol.txt for information about PROXY protocol. Valid values for protocol are TCP, PROXY and omitted. When omitted, this means no opinion and the platform is left to choose a reasonable default, which is subject to change over time. The current default is TCP, without the proxy protocol enabled. 15.1.14. .spec.endpointPublishingStrategy.nodePort Description nodePort holds parameters for the NodePortService endpoint publishing strategy. Present only if type is NodePortService. Type object Property Type Description protocol string protocol specifies whether the IngressController expects incoming connections to use plain TCP or whether the IngressController expects PROXY protocol. PROXY protocol can be used with load balancers that support it to communicate the source addresses of client connections when forwarding those connections to the IngressController. Using PROXY protocol enables the IngressController to report those source addresses instead of reporting the load balancer's address in HTTP headers and logs. Note that enabling PROXY protocol on the IngressController will cause connections to fail if you are not using a load balancer that uses PROXY protocol to forward connections to the IngressController. See http://www.haproxy.org/download/2.2/doc/proxy-protocol.txt for information about PROXY protocol. The following values are valid for this field: * The empty string. * "TCP". * "PROXY". The empty string specifies the default, which is TCP without PROXY protocol. Note that the default is subject to change. 15.1.15. .spec.endpointPublishingStrategy.private Description private holds parameters for the Private endpoint publishing strategy. Present only if type is Private. Type object Property Type Description protocol string protocol specifies whether the IngressController expects incoming connections to use plain TCP or whether the IngressController expects PROXY protocol. PROXY protocol can be used with load balancers that support it to communicate the source addresses of client connections when forwarding those connections to the IngressController. Using PROXY protocol enables the IngressController to report those source addresses instead of reporting the load balancer's address in HTTP headers and logs. Note that enabling PROXY protocol on the IngressController will cause connections to fail if you are not using a load balancer that uses PROXY protocol to forward connections to the IngressController. See http://www.haproxy.org/download/2.2/doc/proxy-protocol.txt for information about PROXY protocol. The following values are valid for this field: * The empty string. * "TCP". * "PROXY". The empty string specifies the default, which is TCP without PROXY protocol. Note that the default is subject to change. 15.1.16. .spec.httpCompression Description httpCompression defines a policy for HTTP traffic compression. By default, there is no HTTP compression. Type object Property Type Description mimeTypes array (string) mimeTypes is a list of MIME types that should have compression applied. This list can be empty, in which case the ingress controller does not apply compression. Note: Not all MIME types benefit from compression, but HAProxy will still use resources to try to compress if instructed to. Generally speaking, text (html, css, js, etc.) formats benefit from compression, but formats that are already compressed (image, audio, video, etc.) benefit little in exchange for the time and cpu spent on compressing again. See https://joehonton.medium.com/the-gzip-penalty-d31bd697f1a2 15.1.17. .spec.httpErrorCodePages Description httpErrorCodePages specifies a configmap with custom error pages. The administrator must create this configmap in the openshift-config namespace. This configmap should have keys in the format "error-page-<error code>.http", where <error code> is an HTTP error code. For example, "error-page-503.http" defines an error page for HTTP 503 responses. Currently only error pages for 503 and 404 responses can be customized. Each value in the configmap should be the full response, including HTTP headers. Eg- https://raw.githubusercontent.com/openshift/router/fadab45747a9b30cc3f0a4b41ad2871f95827a93/images/router/haproxy/conf/error-page-503.http If this field is empty, the ingress controller uses the default error pages. Type object Required name Property Type Description name string name is the metadata.name of the referenced config map 15.1.18. .spec.httpHeaders Description httpHeaders defines policy for HTTP headers. If this field is empty, the default values are used. Type object Property Type Description forwardedHeaderPolicy string forwardedHeaderPolicy specifies when and how the IngressController sets the Forwarded, X-Forwarded-For, X-Forwarded-Host, X-Forwarded-Port, X-Forwarded-Proto, and X-Forwarded-Proto-Version HTTP headers. The value may be one of the following: * "Append", which specifies that the IngressController appends the headers, preserving existing headers. * "Replace", which specifies that the IngressController sets the headers, replacing any existing Forwarded or X-Forwarded-* headers. * "IfNone", which specifies that the IngressController sets the headers if they are not already set. * "Never", which specifies that the IngressController never sets the headers, preserving any existing headers. By default, the policy is "Append". headerNameCaseAdjustments `` headerNameCaseAdjustments specifies case adjustments that can be applied to HTTP header names. Each adjustment is specified as an HTTP header name with the desired capitalization. For example, specifying "X-Forwarded-For" indicates that the "x-forwarded-for" HTTP header should be adjusted to have the specified capitalization. These adjustments are only applied to cleartext, edge-terminated, and re-encrypt routes, and only when using HTTP/1. For request headers, these adjustments are applied only for routes that have the haproxy.router.openshift.io/h1-adjust-case=true annotation. For response headers, these adjustments are applied to all HTTP responses. If this field is empty, no request headers are adjusted. uniqueId object uniqueId describes configuration for a custom HTTP header that the ingress controller should inject into incoming HTTP requests. Typically, this header is configured to have a value that is unique to the HTTP request. The header can be used by applications or included in access logs to facilitate tracing individual HTTP requests. If this field is empty, no such header is injected into requests. 15.1.19. .spec.httpHeaders.uniqueId Description uniqueId describes configuration for a custom HTTP header that the ingress controller should inject into incoming HTTP requests. Typically, this header is configured to have a value that is unique to the HTTP request. The header can be used by applications or included in access logs to facilitate tracing individual HTTP requests. If this field is empty, no such header is injected into requests. Type object Property Type Description format string format specifies the format for the injected HTTP header's value. This field has no effect unless name is specified. For the HAProxy-based ingress controller implementation, this format uses the same syntax as the HTTP log format. If the field is empty, the default value is "%{+X}o\\ %ci:%cp_%fi:%fp_%Ts_%rt:%pid"; see the corresponding HAProxy documentation: http://cbonte.github.io/haproxy-dconv/2.0/configuration.html#8.2.3 name string name specifies the name of the HTTP header (for example, "unique-id") that the ingress controller should inject into HTTP requests. The field's value must be a valid HTTP header name as defined in RFC 2616 section 4.2. If the field is empty, no header is injected. 15.1.20. .spec.logging Description logging defines parameters for what should be logged where. If this field is empty, operational logs are enabled but access logs are disabled. Type object Property Type Description access object access describes how the client requests should be logged. If this field is empty, access logging is disabled. 15.1.21. .spec.logging.access Description access describes how the client requests should be logged. If this field is empty, access logging is disabled. Type object Required destination Property Type Description destination object destination is where access logs go. httpCaptureCookies `` httpCaptureCookies specifies HTTP cookies that should be captured in access logs. If this field is empty, no cookies are captured. httpCaptureHeaders object httpCaptureHeaders defines HTTP headers that should be captured in access logs. If this field is empty, no headers are captured. Note that this option only applies to cleartext HTTP connections and to secure HTTP connections for which the ingress controller terminates encryption (that is, edge-terminated or reencrypt connections). Headers cannot be captured for TLS passthrough connections. httpLogFormat string httpLogFormat specifies the format of the log message for an HTTP request. If this field is empty, log messages use the implementation's default HTTP log format. For HAProxy's default HTTP log format, see the HAProxy documentation: http://cbonte.github.io/haproxy-dconv/2.0/configuration.html#8.2.3 Note that this format only applies to cleartext HTTP connections and to secure HTTP connections for which the ingress controller terminates encryption (that is, edge-terminated or reencrypt connections). It does not affect the log format for TLS passthrough connections. logEmptyRequests string logEmptyRequests specifies how connections on which no request is received should be logged. Typically, these empty requests come from load balancers' health probes or Web browsers' speculative connections ("preconnect"), in which case logging these requests may be undesirable. However, these requests may also be caused by network errors, in which case logging empty requests may be useful for diagnosing the errors. In addition, these requests may be caused by port scans, in which case logging empty requests may aid in detecting intrusion attempts. Allowed values for this field are "Log" and "Ignore". The default value is "Log". 15.1.22. .spec.logging.access.destination Description destination is where access logs go. Type object Required type Property Type Description container object container holds parameters for the Container logging destination. Present only if type is Container. syslog object syslog holds parameters for a syslog endpoint. Present only if type is Syslog. type string type is the type of destination for logs. It must be one of the following: * Container The ingress operator configures the sidecar container named "logs" on the ingress controller pod and configures the ingress controller to write logs to the sidecar. The logs are then available as container logs. The expectation is that the administrator configures a custom logging solution that reads logs from this sidecar. Note that using container logs means that logs may be dropped if the rate of logs exceeds the container runtime's or the custom logging solution's capacity. * Syslog Logs are sent to a syslog endpoint. The administrator must specify an endpoint that can receive syslog messages. The expectation is that the administrator has configured a custom syslog instance. 15.1.23. .spec.logging.access.destination.container Description container holds parameters for the Container logging destination. Present only if type is Container. Type object 15.1.24. .spec.logging.access.destination.syslog Description syslog holds parameters for a syslog endpoint. Present only if type is Syslog. Type object Required address port Property Type Description address string address is the IP address of the syslog endpoint that receives log messages. facility string facility specifies the syslog facility of log messages. If this field is empty, the facility is "local1". maxLength integer maxLength is the maximum length of the syslog message If this field is empty, the maxLength is set to "1024". port integer port is the UDP port number of the syslog endpoint that receives log messages. 15.1.25. .spec.logging.access.httpCaptureHeaders Description httpCaptureHeaders defines HTTP headers that should be captured in access logs. If this field is empty, no headers are captured. Note that this option only applies to cleartext HTTP connections and to secure HTTP connections for which the ingress controller terminates encryption (that is, edge-terminated or reencrypt connections). Headers cannot be captured for TLS passthrough connections. Type object Property Type Description request `` request specifies which HTTP request headers to capture. If this field is empty, no request headers are captured. response `` response specifies which HTTP response headers to capture. If this field is empty, no response headers are captured. 15.1.26. .spec.namespaceSelector Description namespaceSelector is used to filter the set of namespaces serviced by the ingress controller. This is useful for implementing shards. If unset, the default is no filtering. Type object Property Type Description matchExpressions array matchExpressions is a list of label selector requirements.

Valid operators are In, NotIn, Exists and DoesNotExist. values array (string) values is an array of string values. If the operator is In or NotIn, the values array must be non-empty. If the operator is Exists or DoesNotExist, the values array must be empty. This array is replaced during a strategic merge patch. 15.1.29. .spec.nodePlacement Description nodePlacement enables explicit control over the scheduling of the ingress controller. If unset, defaults are used. See NodePlacement for more details. Type object Property Type Description nodeSelector object nodeSelector is the node selector applied to ingress controller deployments. If set, the specified selector is used and replaces the default. If unset, the default depends on the value of the defaultPlacement field in the cluster config.openshift.io/v1/ingresses status. When defaultPlacement is Workers, the default is: kubernetes.io/os: linux node-role.kubernetes.io/worker: '' When defaultPlacement is ControlPlane, the default is: kubernetes.io/os: linux node-role.kubernetes.io/master: '' These defaults are subject to change. Note that using nodeSelector.matchExpressions is not supported. Only nodeSelector.matchLabels may be used. This is a limitation of the Kubernetes API: the pod spec does not allow complex expressions for node selectors. tolerations array tolerations is a list of tolerations applied to ingress controller deployments. The default is an empty list. See https://kubernetes.io/docs/concepts/configuration/taint-and-toleration/ tolerations[] object The pod this Toleration is attached to tolerates any taint that matches the triple <key,value,effect> using the matching operator <operator>. 15.1.30. .spec.nodePlacement.nodeSelector Description nodeSelector is the node selector applied to ingress controller deployments. If set, the specified selector is used and replaces the default. If unset, the default depends on the value of the defaultPlacement field in the cluster config.openshift.io/v1/ingresses status. When defaultPlacement is Workers, the default is: kubernetes.io/os: linux node-role.kubernetes.io/worker: '' When defaultPlacement is ControlPlane, the default is: kubernetes.io/os: linux node-role.kubernetes.io/master: '' These defaults are subject to change. Note that using nodeSelector.matchExpressions is not supported. Only nodeSelector.matchLabels may be used.

Type object Property Type Description matchExpressions array matchExpressions is a list of label selector requirements. The requirements are ANDed. matchExpressions[] object A label selector requirement is a selector that contains values, a key, and an operator that relates the key and values. matchLabels object (string) matchLabels is a map of {key,value} pairs. A single {key,value} in the matchLabels map is equivalent to an element of matchExpressions, whose key field is "key", the operator is "In", and the values array contains only "value". The requirements are ANDed. 15.1.31. .spec.nodePlacement.nodeSelector.matchExpressions Description matchExpressions is a list of label selector requirements. The requirements are ANDed. Type array 15.1.32. .spec.nodePlacement.nodeSelector.matchExpressions[] Description A label selector requirement is a selector that contains values, a key, and an operator that relates the key and values. Type object Required key operator Property Type Description key string key is the label key that the selector applies to. operator string operator represents a key's relationship to a set of values. Valid operators are In, NotIn, Exists and DoesNotExist. values array (string) values is an array of string values. If the operator is In or NotIn, the values array must be non-empty. If the operator is Exists or DoesNotExist, the values array must be empty. This array is replaced during a strategic merge patch. 15.1.33. .spec.nodePlacement.tolerations Description tolerations is a list of tolerations applied to ingress controller deployments. The default is an empty list. See https://kubernetes.io/docs/concepts/configuration/taint-and-toleration/ Type array 15.1.34. .spec.nodePlacement.tolerations[] Description The pod this Toleration is attached to tolerates any taint that matches the triple <key,value,effect> using the matching operator <operator>. Type object Property Type Description effect string Effect indicates the taint effect to match. Empty means match all taint effects. When specified, allowed values are NoSchedule, PreferNoSchedule and NoExecute. key string Key is the taint key that the toleration applies to. Empty means match all taint keys. If the key is empty, operator must be Exists; this combination means to match all values and all keys. operator string Operator represents a key's relationship to the value. Valid operators are Exists and Equal. Defaults to Equal. Exists is equivalent to wildcard for value, so that a pod can tolerate all taints of a particular category. tolerationSeconds integer TolerationSeconds represents the period of time the toleration (which must be of effect NoExecute, otherwise this field is ignored) tolerates the taint. By default, it is not set, which means tolerate the taint forever (do not evict). Zero and negative values will be treated as 0 (evict immediately) by the system. value string Value is the taint value the toleration matches to. If the operator is Exists, the value should be empty, otherwise just a regular string. 15.1.35. .spec.routeAdmission Description routeAdmission defines a policy for handling new route claims (for example, to allow or deny claims across namespaces). If empty, defaults will be applied. See specific routeAdmission fields for details about their defaults. Type object Property Type Description namespaceOwnership string namespaceOwnership describes how host name claims across namespaces should be handled. Value must be one of: - Strict: Do not allow routes in different namespaces to claim the same host. - InterNamespaceAllowed: Allow routes to claim different paths of the same host name across namespaces. If empty, the default is Strict. wildcardPolicy string wildcardPolicy describes how routes with wildcard policies should be handled for the ingress controller. WildcardPolicy controls use of routes [1] exposed by the ingress controller based on the route's wildcard policy. [1] https://github.com/openshift/api/blob/master/route/v1/types.go Note: Updating WildcardPolicy from WildcardsAllowed to WildcardsDisallowed will cause admitted routes with a wildcard policy of Subdomain to stop working. These routes must be updated to a wildcard policy of None to be readmitted by the ingress controller. WildcardPolicy supports WildcardsAllowed and WildcardsDisallowed values. If empty, defaults to "WildcardsDisallowed". 15.1.36. .spec.routeSelector Description routeSelector is used to filter the set of Routes serviced by the ingress controller. This is useful for implementing shards. If unset, the default is no filtering. Type object Property Type Description matchExpressions array matchExpressions is a list of label selector requirements. The requirements are ANDed. matchExpressions[] object A label selector requirement is a selector that contains values, a key, and an operator that relates the key and values. matchLabels object (string) matchLabels is a map of {key,value} pairs. A single {key,value} in the matchLabels map is equivalent to an element of matchExpressions, whose key field is "key", the operator is "In", and the values array contains only "value". The requirements are ANDed. 15.1.37. .spec.routeSelector.matchExpressions Description matchExpressions is a list of label selector requirements. The requirements are ANDed. Type array 15.1.38. .spec.routeSelector.matchExpressions[] Description A label selector requirement is a selector that contains values, a key, and an operator that relates the key and values.

Valid operators are In, NotIn, Exists and DoesNotExist. values array (string) values is an array of string values. If the operator is In or NotIn, the values array must be non-empty. If the operator is Exists or DoesNotExist, the values array must be empty. This array is replaced during a strategic merge patch. 15.1.39. .spec.tlsSecurityProfile Description tlsSecurityProfile specifies settings for TLS connections for ingresscontrollers. If unset, the default is based on the apiservers.config.openshift.io/cluster resource. Note that when using the Old, Intermediate, and Modern profile types, the effective profile configuration is subject to change between releases. For example, given a specification to use the Intermediate profile deployed on release X.Y.Z, an upgrade to release X.Y.Z+1 may cause a new profile configuration to be applied to the ingress controller, resulting in a rollout. Type object Property Type Description custom `` custom is a user-defined TLS security profile. Be extremely careful using a custom profile as invalid configurations can be catastrophic. An example custom profile looks like this: ciphers: - ECDHE-ECDSA-CHACHA20-POLY1305 - ECDHE-RSA-CHACHA20-POLY1305 - ECDHE-RSA-AES128-GCM-SHA256 - ECDHE-ECDSA-AES128-GCM-SHA256 minTLSVersion: TLSv1.1 intermediate `` intermediate is a TLS security profile based on: https://wiki.mozilla.org/Security/Server_Side_TLS#Intermediate_compatibility_.28recommended.29 and looks like this (yaml): ciphers: - TLS_AES_128_GCM_SHA256 - TLS_AES_256_GCM_SHA384 - TLS_CHACHA20_POLY1305_SHA256 - ECDHE-ECDSA-AES128-GCM-SHA256 - ECDHE-RSA-AES128-GCM-SHA256 - ECDHE-ECDSA-AES256-GCM-SHA384 - ECDHE-RSA-AES256-GCM-SHA384 - ECDHE-ECDSA-CHACHA20-POLY1305 - ECDHE-RSA-CHACHA20-POLY1305 - DHE-RSA-AES128-GCM-SHA256 - DHE-RSA-AES256-GCM-SHA384 minTLSVersion: TLSv1.2 modern `` modern is a TLS security profile based on: https://wiki.mozilla.org/Security/Server_Side_TLS#Modern_compatibility and looks like this (yaml): ciphers: - TLS_AES_128_GCM_SHA256 - TLS_AES_256_GCM_SHA384 - TLS_CHACHA20_POLY1305_SHA256 minTLSVersion: TLSv1.3 NOTE: Currently unsupported. old `` old is a TLS security profile based on: https://wiki.mozilla.org/Security/Server_Side_TLS#Old_backward_compatibility and looks like this (yaml): ciphers: - TLS_AES_128_GCM_SHA256 - TLS_AES_256_GCM_SHA384 - TLS_CHACHA20_POLY1305_SHA256 - ECDHE-ECDSA-AES128-GCM-SHA256 - ECDHE-RSA-AES128-GCM-SHA256 - ECDHE-ECDSA-AES256-GCM-SHA384 - ECDHE-RSA-AES256-GCM-SHA384 - ECDHE-ECDSA-CHACHA20-POLY1305 - ECDHE-RSA-CHACHA20-POLY1305 - DHE-RSA-AES128-GCM-SHA256 - DHE-RSA-AES256-GCM-SHA384 - DHE-RSA-CHACHA20-POLY1305 - ECDHE-ECDSA-AES128-SHA256 - ECDHE-RSA-AES128-SHA256 - ECDHE-ECDSA-AES128-SHA - ECDHE-RSA-AES128-SHA - ECDHE-ECDSA-AES256-SHA384 - ECDHE-RSA-AES256-SHA384 - ECDHE-ECDSA-AES256-SHA - ECDHE-RSA-AES256-SHA - DHE-RSA-AES128-SHA256 - DHE-RSA-AES256-SHA256 - AES128-GCM-SHA256 - AES256-GCM-SHA384 - AES128-SHA256 - AES256-SHA256 - AES128-SHA - AES256-SHA - DES-CBC3-SHA minTLSVersion: TLSv1.0 type string type is one of Old, Intermediate, Modern or Custom. Custom provides the ability to specify individual TLS security profile parameters. Old, Intermediate and Modern are TLS security profiles based on: https://wiki.mozilla.org/Security/Server_Side_TLS#Recommended_configurations The profiles are intent based, so they may change over time as new ciphers are developed and existing ciphers are found to be insecure. Depending on precisely which ciphers are available to a process, the list may be reduced. Note that the Modern profile is currently not supported because it is not yet well adopted by common software libraries. 15.1.40. .spec.tuningOptions Description tuningOptions defines parameters for adjusting the performance of ingress controller pods. All fields are optional and will use their respective defaults if not set. See specific tuningOptions fields for more details. Setting fields within tuningOptions is generally not recommended. The default values are suitable for most configurations. Type object Property Type Description clientFinTimeout string clientFinTimeout defines how long a connection will be held open while waiting for the client response to the server/backend closing the connection. If unset, the default timeout is 1s clientTimeout string clientTimeout defines how long a connection will be held open while waiting for a client response. If unset, the default timeout is 30s headerBufferBytes integer headerBufferBytes describes how much memory should be reserved (in bytes) for IngressController connection sessions. Note that this value must be at least 16384 if HTTP/2 is enabled for the IngressController ( https://tools.ietf.org/html/rfc7540 ). If this field is empty, the IngressController will use a default value of 32768 bytes. Setting this field is generally not recommended as headerBufferBytes values that are too small may break the IngressController and headerBufferBytes values that are too large could cause the IngressController to use significantly more memory than necessary. headerBufferMaxRewriteBytes integer headerBufferMaxRewriteBytes describes how much memory should be reserved (in bytes) from headerBufferBytes for HTTP header rewriting and appending for IngressController connection sessions. Note that incoming HTTP requests will be limited to (headerBufferBytes - headerBufferMaxRewriteBytes) bytes, meaning headerBufferBytes must be greater than headerBufferMaxRewriteBytes. If this field is empty, the IngressController will use a default value of 8192 bytes. Setting this field is generally not recommended as headerBufferMaxRewriteBytes values that are too small may break the IngressController and headerBufferMaxRewriteBytes values that are too large could cause the IngressController to use significantly more memory than necessary. healthCheckInterval string healthCheckInterval defines how long the router waits between two consecutive health checks on its configured backends. This value is applied globally as a default for all routes, but may be overridden per-route by the route annotation "router.openshift.io/haproxy.health.check.interval". Expects an unsigned duration string of decimal numbers, each with optional fraction and a unit suffix, eg "300ms", "1.5h" or "2h45m". Valid time units are "ns", "us" (or "ms" U+00B5 or "ms" U+03BC), "ms", "s", "m", "h". Setting this to less than 5s can cause excess traffic due to too frequent TCP health checks and accompanying SYN packet storms. Alternatively, setting this too high can result in increased latency, due to backend servers that are no longer available, but haven't yet been detected as such. An empty or zero healthCheckInterval means no opinion and IngressController chooses a default, which is subject to change over time. Currently the default healthCheckInterval value is 5s. Currently the minimum allowed value is 1s and the maximum allowed value is 2147483647ms (24.85 days). Both are subject to change over time. maxConnections integer maxConnections defines the maximum number of simultaneous connections that can be established per HAProxy process. Increasing this value allows each ingress controller pod to handle more connections but at the cost of additional system resources being consumed. Permitted values are: empty, 0, -1, and the range 2000-2000000. If this field is empty or 0, the IngressController will use the default value of 50000, but the default is subject to change in future releases. If the value is -1 then HAProxy will dynamically compute a maximum value based on the available ulimits in the running container. Selecting -1 (i.e., auto) will result in a large value being computed (~520000 on OpenShift >=4.10 clusters) and therefore each HAProxy process will incur significant memory usage compared to the current default of 50000. Setting a value that is greater than the current operating system limit will prevent the HAProxy process from starting. If you choose a discrete value (e.g., 750000) and the router pod is migrated to a new node, there's no guarantee that that new node has identical ulimits configured. In such a scenario the pod would fail to start. If you have nodes with different ulimits configured (e.g., different tuned profiles) and you choose a discrete value then the guidance is to use -1 and let the value be computed dynamically at runtime. You can monitor memory usage for router containers with the following metric: 'container_memory_working_set_bytes{container="router",namespace="openshift-ingress"}'. You can monitor memory usage of individual HAProxy processes in router containers with the following metric: 'container_memory_working_set_bytes{container="router",namespace="openshift-ingress"}/container_processes{container="router",namespace="openshift-ingress"}'. reloadInterval string reloadInterval defines the minimum interval at which the router is allowed to reload to accept new changes. Increasing this value can prevent the accumulation of HAProxy processes, depending on the scenario. Increasing this interval can also lessen load imbalance on a backend's servers when using the roundrobin balancing algorithm. Alternatively, decreasing this value may decrease latency since updates to HAProxy's configuration can take effect more quickly. The value must be a time duration value; see https://pkg.go.dev/time#ParseDuration . Currently, the minimum value allowed is 1s, and the maximum allowed value is 120s. Minimum and maximum allowed values may change in future versions of OpenShift. Note that if a duration outside of these bounds is provided, the value of reloadInterval will be capped/floored and not rejected (e.g. a duration of over 120s will be capped to 120s; the IngressController will not reject and replace this disallowed value with the default). A zero value for reloadInterval tells the IngressController to choose the default, which is currently 5s and subject to change without notice. This field expects an unsigned duration string of decimal numbers, each with optional fraction and a unit suffix, e.g. "300ms", "1.5h" or "2h45m". Valid time units are "ns", "us" (or "ms" U+00B5 or "ms" U+03BC), "ms", "s", "m", "h". Note: Setting a value significantly larger than the default of 5s can cause latency in observing updates to routes and their endpoints. HAProxy's configuration will be reloaded less frequently, and newly created routes will not be served until the subsequent reload. serverFinTimeout string serverFinTimeout defines how long a connection will be held open while waiting for the server/backend response to the client closing the connection. If unset, the default timeout is 1s serverTimeout string serverTimeout defines how long a connection will be held open while waiting for a server/backend response. If unset, the default timeout is 30s threadCount integer threadCount defines the number of threads created per HAProxy process. Creating more threads allows each ingress controller pod to handle more connections, at the cost of more system resources being used. HAProxy currently supports up to 64 threads. If this field is empty, the IngressController will use the default value. The current default is 4 threads, but this may change in future releases. Setting this field is generally not recommended. Increasing the number of HAProxy threads allows ingress controller pods to utilize more CPU time under load, potentially starving other pods if set too high. Reducing the number of threads may cause the ingress controller to perform poorly. tlsInspectDelay string tlsInspectDelay defines how long the router can hold data to find a matching route. Setting this too short can cause the router to fall back to the default certificate for edge-terminated or reencrypt routes even when a better matching certificate could be used. If unset, the default inspect delay is 5s tunnelTimeout string tunnelTimeout defines how long a tunnel connection (including websockets) will be held open while the tunnel is idle. If unset, the default timeout is 1h 15.1.41. .status Description status is the most recently observed status of the IngressController. Type object Property Type Description availableReplicas integer availableReplicas is number of observed available replicas according to the ingress controller deployment. conditions array conditions is a list of conditions and their status. Available means the ingress controller deployment is available and servicing route and ingress resources (i.e, .status.availableReplicas equals .spec.replicas) There are additional conditions which indicate the status of other ingress controller features and capabilities. * LoadBalancerManaged - True if the following conditions are met: * The endpoint publishing strategy requires a service load balancer. - False if any of those conditions are unsatisfied. * LoadBalancerReady - True if the following conditions are met: * A load balancer is managed. * The load balancer is ready. - False if any of those conditions are unsatisfied. * DNSManaged - True if the following conditions are met: * The endpoint publishing strategy and platform support DNS. * The ingress controller domain is set. * dns.config.openshift.io/cluster configures DNS zones. - False if any of those conditions are unsatisfied. * DNSReady - True if the following conditions are met: * DNS is managed. * DNS records have been successfully created. - False if any of those conditions are unsatisfied. conditions[] object OperatorCondition is just the standard condition fields. domain string domain is the actual domain in use. endpointPublishingStrategy object endpointPublishingStrategy is the actual strategy in use. namespaceSelector object namespaceSelector is the actual namespaceSelector in use. observedGeneration integer observedGeneration is the most recent generation observed. routeSelector object routeSelector is the actual routeSelector in use. selector string selector is a label selector, in string format, for ingress controller pods corresponding to the IngressController. The number of matching pods should equal the value of availableReplicas. tlsProfile object tlsProfile is the TLS connection configuration that is in effect. 15.1.42. .status.conditions Description conditions is a list of conditions and their status. Available means the ingress controller deployment is available and servicing route and ingress resources (i.e, .status.availableReplicas equals .spec.replicas) There are additional conditions which indicate the status of other ingress controller features and capabilities. * LoadBalancerManaged - True if the following conditions are met: * The endpoint publishing strategy requires a service load balancer. - False if any of those conditions are unsatisfied. * LoadBalancerReady - True if the following conditions are met: * A load balancer is managed. * The load balancer is ready. - False if any of those conditions are unsatisfied. * DNSManaged - True if the following conditions are met: * The endpoint publishing strategy and platform support DNS. * The ingress controller domain is set. * dns.config.openshift.io/cluster configures DNS zones. - False if any of those conditions are unsatisfied. * DNSReady - True if the following conditions are met: * DNS is managed. * DNS records have been successfully created. - False if any of those conditions are unsatisfied. Type array 15.1.43. .status.conditions[] Description OperatorCondition is just the standard condition fields. Type object Property Type Description lastTransitionTime string message string reason string status string type string 15.1.44. .status.endpointPublishingStrategy Description endpointPublishingStrategy is the actual strategy in use. Type object Required type Property Type Description hostNetwork object hostNetwork holds parameters for the HostNetwork endpoint publishing strategy. Present only if type is HostNetwork. loadBalancer object loadBalancer holds parameters for the load balancer. Present only if type is LoadBalancerService. nodePort object nodePort holds parameters for the NodePortService endpoint publishing strategy. Present only if type is NodePortService. private object private holds parameters for the Private endpoint publishing strategy. Present only if type is Private. type string type is the publishing strategy to use. Valid values are: * LoadBalancerService Publishes the ingress controller using a Kubernetes LoadBalancer Service. In this configuration, the ingress controller deployment uses container networking. A LoadBalancer Service is created to publish the deployment. See: https://kubernetes.io/docs/concepts/services-networking/service/#loadbalancer If domain is set, a wildcard DNS record will be managed to point at the LoadBalancer Service's external name. DNS records are managed only in DNS zones defined by dns.config.openshift.io/cluster .spec.publicZone and .spec.privateZone. Wildcard DNS management is currently supported only on the AWS, Azure, and GCP platforms. * HostNetwork Publishes the ingress controller on node ports where the ingress controller is deployed. In this configuration, the ingress controller deployment uses host networking, bound to node ports 80 and 443. The user is responsible for configuring an external load balancer to publish the ingress controller via the node ports. * Private Does not publish the ingress controller. In this configuration, the ingress controller deployment uses container networking, and is not explicitly published. The user must manually publish the ingress controller. * NodePortService Publishes the ingress controller using a Kubernetes NodePort Service. In this configuration, the ingress controller deployment uses container networking. A NodePort Service is created to publish the deployment. The specific node ports are dynamically allocated by OpenShift; however, to support static port allocations, user changes to the node port field of the managed NodePort Service will preserved. 15.1.45. .status.endpointPublishingStrategy.hostNetwork Description hostNetwork holds parameters for the HostNetwork endpoint publishing strategy. Present only if type is HostNetwork. Type object Property Type Description httpPort integer httpPort is the port on the host which should be used to listen for HTTP requests. This field should be set when port 80 is already in use. The value should not coincide with the NodePort range of the cluster. When the value is 0 or is not specified it defaults to 80. httpsPort integer httpsPort is the port on the host which should be used to listen for HTTPS requests. This field should be set when port 443 is already in use. The value should not coincide with the NodePort range of the cluster. When the value is 0 or is not specified it defaults to 443. protocol string protocol specifies whether the IngressController expects incoming connections to use plain TCP or whether the IngressController expects PROXY protocol. PROXY protocol can be used with load balancers that support it to communicate the source addresses of client connections when forwarding those connections to the IngressController. Using PROXY protocol enables the IngressController to report those source addresses instead of reporting the load balancer's address in HTTP headers and logs. Note that enabling PROXY protocol on the IngressController will cause connections to fail if you are not using a load balancer that uses PROXY protocol to forward connections to the IngressController. See http://www.haproxy.org/download/2.2/doc/proxy-protocol.txt for information about PROXY protocol. The following values are valid for this field: * The empty string. * "TCP". * "PROXY". The empty string specifies the default, which is TCP without PROXY protocol. Note that the default is subject to change. statsPort integer statsPort is the port on the host where the stats from the router are published. The value should not coincide with the NodePort range of the cluster. If an external load balancer is configured to forward connections to this IngressController, the load balancer should use this port for health checks. The load balancer can send HTTP probes on this port on a given node, with the path /healthz/ready to determine if the ingress controller is ready to receive traffic on the node. For proper operation the load balancer must not forward traffic to a node until the health check reports ready. The load balancer should also stop forwarding requests within a maximum of 45 seconds after /healthz/ready starts reporting not-ready. Probing every 5 to 10 seconds, with a 5-second timeout and with a threshold of two successful or failed requests to become healthy or unhealthy respectively, are well-tested values. When the value is 0 or is not specified it defaults to 1936. 15.1.46. .status.endpointPublishingStrategy.loadBalancer Description loadBalancer holds parameters for the load balancer. Present only if type is LoadBalancerService. Type object Required dnsManagementPolicy scope Property Type Description allowedSourceRanges `` allowedSourceRanges specifies an allowlist of IP address ranges to which access to the load balancer should be restricted. Each range must be specified using CIDR notation (e.g. "10.0.0.0/8" or "fd00::/8"). If no range is specified, "0.0.0.0/0" for IPv4 and "::/0" for IPv6 are used by default, which allows all source addresses. To facilitate migration from earlier versions of OpenShift that did not have the allowedSourceRanges field, you may set the service.beta.kubernetes.io/load-balancer-source-ranges annotation on the "router-<ingresscontroller name>" service in the "openshift-ingress" namespace, and this annotation will take effect if allowedSourceRanges is empty on OpenShift 4.12. dnsManagementPolicy string dnsManagementPolicy indicates if the lifecycle of the wildcard DNS record associated with the load balancer service will be managed by the ingress operator. It defaults to Managed. Valid values are: Managed and Unmanaged. providerParameters object providerParameters holds desired load balancer information specific to the underlying infrastructure provider. If empty, defaults will be applied. See specific providerParameters fields for details about their defaults. scope string scope indicates the scope at which the load balancer is exposed. Possible values are "External" and "Internal". 15.1.47. .status.endpointPublishingStrategy.loadBalancer.providerParameters Description providerParameters holds desired load balancer information specific to the underlying infrastructure provider.

If empty, defaults will be applied. See specific aws fields for details about their defaults. Type object Required type Property Type Description classicLoadBalancer object classicLoadBalancerParameters holds configuration parameters for an AWS classic load balancer. Present only if type is Classic. networkLoadBalancer object networkLoadBalancerParameters holds configuration parameters for an AWS network load balancer. Present only if type is NLB. type string type is the type of AWS load balancer to instantiate for an ingresscontroller. Valid values are: * "Classic": A Classic Load Balancer that makes routing decisions at either the transport layer (TCP/SSL) or the application layer (HTTP/HTTPS). See the following for additional details: https://docs.aws.amazon.com/AmazonECS/latest/developerguide/load-balancer-types.html#clb * "NLB": A Network Load Balancer that makes routing decisions at the transport layer (TCP/SSL). See the following for additional details: https://docs.aws.amazon.com/AmazonECS/latest/developerguide/load-balancer-types.html#nlb 15.1.49. .status.endpointPublishingStrategy.loadBalancer.providerParameters.aws.classicLoadBalancer Description classicLoadBalancerParameters holds configuration parameters for an AWS classic load balancer. Present only if type is Classic. Type object Property Type Description connectionIdleTimeout string connectionIdleTimeout specifies the maximum time period that a connection may be idle before the load balancer closes the connection. The value must be parseable as a time duration value; see https://pkg.go.dev/time#ParseDuration . A nil or zero value means no opinion, in which case a default value is used. The default value for this field is 60s. This default is subject to change. 15.1.50. .status.endpointPublishingStrategy.loadBalancer.providerParameters.aws.networkLoadBalancer Description networkLoadBalancerParameters holds configuration parameters for an AWS network load balancer. Present only if type is NLB. Type object 15.1.51. .status.endpointPublishingStrategy.loadBalancer.providerParameters.gcp Description gcp provides configuration settings that are specific to GCP load balancers. If empty, defaults will be applied. See specific gcp fields for details about their defaults. Type object Property Type Description clientAccess string clientAccess describes how client access is restricted for internal load balancers. Valid values are: * "Global": Specifying an internal load balancer with Global client access allows clients from any region within the VPC to communicate with the load balancer. https://cloud.google.com/kubernetes-engine/docs/how-to/internal-load-balancing#global_access * "Local": Specifying an internal load balancer with Local client access means only clients within the same region (and VPC) as the GCP load balancer can communicate with the load balancer. Note that this is the default behavior. https://cloud.google.com/load-balancing/docs/internal#client_access 15.1.52. .status.endpointPublishingStrategy.loadBalancer.providerParameters.ibm Description ibm provides configuration settings that are specific to IBM Cloud load balancers. If empty, defaults will be applied. See specific ibm fields for details about their defaults. Type object Property Type Description protocol string protocol specifies whether the load balancer uses PROXY protocol to forward connections to the IngressController. See "service.kubernetes.io/ibm-load-balancer-cloud-provider-enable-features: "proxy-protocol"" at https://cloud.ibm.com/docs/containers?topic=containers-vpc-lbaas PROXY protocol can be used with load balancers that support it to communicate the source addresses of client connections when forwarding those connections to the IngressController. Using PROXY protocol enables the IngressController to report those source addresses instead of reporting the load balancer's address in HTTP headers and logs. Note that enabling PROXY protocol on the IngressController will cause connections to fail if you are not using a load balancer that uses PROXY protocol to forward connections to the IngressController. See http://www.haproxy.org/download/2.2/doc/proxy-protocol.txt for information about PROXY protocol. Valid values for protocol are TCP, PROXY and omitted. When omitted, this means no opinion and the platform is left to choose a reasonable default, which is subject to change over time. The current default is TCP, without the proxy protocol enabled. 15.1.53. .status.endpointPublishingStrategy.nodePort Description nodePort holds parameters for the NodePortService endpoint publishing strategy. Present only if type is NodePortService. Type object Property Type Description protocol string protocol specifies whether the IngressController expects incoming connections to use plain TCP or whether the IngressController expects PROXY protocol. PROXY protocol can be used with load balancers that support it to communicate the source addresses of client connections when forwarding those connections to the IngressController. Using PROXY protocol enables the IngressController to report those source addresses instead of reporting the load balancer's address in HTTP headers and logs. Note that enabling PROXY protocol on the IngressController will cause connections to fail if you are not using a load balancer that uses PROXY protocol to forward connections to the IngressController. See http://www.haproxy.org/download/2.2/doc/proxy-protocol.txt for information about PROXY protocol. The following values are valid for this field: * The empty string. * "TCP". * "PROXY". The empty string specifies the default, which is TCP without PROXY protocol. Note that the default is subject to change. 15.1.54. .status.endpointPublishingStrategy.private Description private holds parameters for the Private endpoint publishing strategy. Present only if type is Private. Type object Property Type Description protocol string protocol specifies whether the IngressController expects incoming connections to use plain TCP or whether the IngressController expects PROXY protocol. PROXY protocol can be used with load balancers that support it to communicate the source addresses of client connections when forwarding those connections to the IngressController. Using PROXY protocol enables the IngressController to report those source addresses instead of reporting the load balancer's address in HTTP headers and logs. Note that enabling PROXY protocol on the IngressController will cause connections to fail if you are not using a load balancer that uses PROXY protocol to forward connections to the IngressController. See http://www.haproxy.org/download/2.2/doc/proxy-protocol.txt for information about PROXY protocol. The following values are valid for this field: * The empty string. * "TCP". * "PROXY". The empty string specifies the default, which is TCP without PROXY protocol. Note that the default is subject to change. 15.1.55. .status.namespaceSelector Description namespaceSelector is the actual namespaceSelector in use. Type object Property Type Description matchExpressions array matchExpressions is a list of label selector requirements. The requirements are ANDed. matchExpressions[] object A label selector requirement is a selector that contains values, a key, and an operator that relates the key and values. matchLabels object (string) matchLabels is a map of {key,value} pairs. A single {key,value} in the matchLabels map is equivalent to an element of matchExpressions, whose key field is "key", the operator is "In", and the values array contains only "value". The requirements are ANDed. 15.1.56. .status.namespaceSelector.matchExpressions Description matchExpressions is a list of label selector requirements. The requirements are ANDed. Type array 15.1.57. .status.namespaceSelector.matchExpressions[] Description A label selector requirement is a selector that contains values, a key, and an operator that relates the key and values. Type object Required key operator Property Type Description key string key is the label key that the selector applies to. operator string operator represents a key's relationship to a set of values. Valid operators are In, NotIn, Exists and DoesNotExist. values array (string) values is an array of string values. If the operator is In or NotIn, the values array must be non-empty. If the operator is Exists or DoesNotExist, the values array must be empty. This array is replaced during a strategic merge patch. 15.1.58. .status.routeSelector Description routeSelector is the actual routeSelector in use. Type object Property Type Description matchExpressions array matchExpressions is a list of label selector requirements. The requirements are ANDed. matchExpressions[] object A label selector requirement is a selector that contains values, a key, and an operator that relates the key and values. matchLabels object (string) matchLabels is a map of {key,value} pairs.

Type array 15.1.60. .status.routeSelector.matchExpressions[] Description A label selector requirement is a selector that contains values, a key, and an operator that relates the key and values. Type object Required key operator Property Type Description key string key is the label key that the selector applies to. operator string operator represents a key's relationship to a set of values. Valid operators are In, NotIn, Exists and DoesNotExist. values array (string) values is an array of string values. If the operator is In or NotIn, the values array must be non-empty. If the operator is Exists or DoesNotExist, the values array must be empty. This array is replaced during a strategic merge patch. 15.1.61. .status.tlsProfile Description tlsProfile is the TLS connection configuration that is in effect. Type object Property Type Description ciphers array (string) ciphers is used to specify the cipher algorithms that are negotiated during the TLS handshake. Operators may remove entries their operands do not support. For example, to use DES-CBC3-SHA (yaml): ciphers: - DES-CBC3-SHA minTLSVersion string minTLSVersion is used to specify the minimal version of the TLS protocol that is negotiated during the TLS handshake. For example, to use TLS versions 1.1, 1.2 and 1.3 (yaml): minTLSVersion: TLSv1.1 NOTE: currently the highest minTLSVersion allowed is VersionTLS12 15.2. API endpoints The following API endpoints are available: /apis/operator.openshift.io/v1/ingresscontrollers GET : list objects of kind IngressController /apis/operator.openshift.io/v1/namespaces/{namespace}/ingresscontrollers DELETE : delete collection of IngressController GET : list objects of kind IngressController POST : create an IngressController /apis/operator.openshift.io/v1/namespaces/{namespace}/ingresscontrollers/{name} DELETE : delete an IngressController GET : read the specified IngressController PATCH : partially update the specified IngressController PUT : replace the specified IngressController /apis/operator.openshift.io/v1/namespaces/{namespace}/ingresscontrollers/{name}/scale GET : read scale of the specified IngressController PATCH : partially update scale of the specified IngressController PUT : replace scale of the specified IngressController /apis/operator.openshift.io/v1/namespaces/{namespace}/ingresscontrollers/{name}/status GET : read status of the specified IngressController PATCH : partially update status of the specified IngressController PUT : replace status of the specified IngressController 15.2.1. /apis/operator.openshift.io/v1/ingresscontrollers Table 15.1. Global query parameters Parameter Type Description allowWatchBookmarks boolean allowWatchBookmarks requests watch events with type "BOOKMARK". Servers that do not implement bookmarks may ignore this flag and bookmarks are sent at the server's discretion. Clients should not assume bookmarks are returned at any specific interval, nor may they assume the server will send any BOOKMARK event during a session. If this is not a watch, this field is ignored. continue string The continue option should be set when retrieving more results from the server. Since this value is server defined, clients may only use the continue value from a query result with identical query parameters (except for the value of continue) and the server may reject a continue value it does not recognize. If the specified continue value is no longer valid whether due to expiration (generally five to fifteen minutes) or a configuration change on the server, the server will respond with a 410 ResourceExpired error together with a continue token. If the client needs a consistent list, it must restart their list without the continue field. Otherwise, the client may send another list request with the token received with the 410 error, the server will respond with a list starting from the key, but from the latest snapshot, which is inconsistent from the list results - objects that are created, modified, or deleted after the first list request will be included in the response, as long as their keys are after the " key". This field is not supported when watch is true. Clients may start a watch from the last resourceVersion value returned by the server and not miss any modifications. fieldSelector string A selector to restrict the list of returned objects by their fields. Defaults to everything. labelSelector string A selector to restrict the list of returned objects by their labels. Defaults to everything. limit integer limit is a maximum number of responses to return for a list call. If more items exist, the server will set the continue field on the list metadata to a value that can be used with the same initial query to retrieve the set of results. Setting a limit may return fewer than the requested amount of items (up to zero items) in the event all requested objects are filtered out and clients should only use the presence of the continue field to determine whether more results are available. Servers may choose not to support the limit argument and will return all of the available results. If limit is specified and the continue field is empty, clients may assume that no more results are available. This field is not supported if watch is true. The server guarantees that the objects returned when using continue will be identical to issuing a single list call without a limit - that is, no objects created, modified, or deleted after the first request is issued will be included in any subsequent continued requests. This is sometimes referred to as a consistent snapshot, and ensures that a client that is using limit to receive smaller chunks of a very large result can ensure they see all possible objects. If objects are updated during a chunked list the version of the object that was present at the time the first list result was calculated is returned. pretty string If 'true', then the output is pretty printed. resourceVersion string resourceVersion sets a constraint on what resource versions a request may be served from. See https://kubernetes.io/docs/reference/using-api/api-concepts/#resource-versions for details. Defaults to unset resourceVersionMatch string resourceVersionMatch determines how resourceVersion is applied to list calls. It is highly recommended that resourceVersionMatch be set for list calls where resourceVersion is set See https://kubernetes.io/docs/reference/using-api/api-concepts/#resource-versions for details. Defaults to unset timeoutSeconds integer Timeout for the list/watch call. This limits the duration of the call, regardless of any activity or inactivity. watch boolean Watch for changes to the described resources and return them as a stream of add, update, and remove notifications.
