Chapter 17. Network [config.openshift.io/v1] Description Network holds cluster-wide information about Network. The canonical name is cluster . It is used to configure the desired network configuration, such as: IP address pools for services/pod IPs, network plugin, etc. Please view network.spec for an explanation on what applies when configuring this resource. Compatibility level 1: Stable within a major release for a minimum of 12 months or 3 minor releases (whichever is longer). Type object Required spec 17.1. 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 holds user settable values for configuration. As a general rule, this SHOULD NOT be read directly. Instead, you should consume the NetworkStatus, as it indicates the currently deployed configuration. Currently, most spec fields are immutable after installation. Please view the individual ones for further details on each. status object status holds observed values from the cluster. They may not be overridden. 17.1.1. .spec Description spec holds user settable values for configuration. As a general rule, this SHOULD NOT be read directly. Instead, you should consume the NetworkStatus, as it indicates the currently deployed configuration. Currently, most spec fields are immutable after installation. Please view the individual ones for further details on each. Type object Property Type Description clusterNetwork array IP address pool to use for pod IPs. This field is immutable after installation. clusterNetwork[] object ClusterNetworkEntry is a contiguous block of IP addresses from which pod IPs are allocated. externalIP object externalIP defines configuration for controllers that affect Service.ExternalIP. If nil, then ExternalIP is not allowed to be set. networkDiagnostics object networkDiagnostics defines network diagnostics configuration. Takes precedence over spec.disableNetworkDiagnostics in network.operator.openshift.io. If networkDiagnostics is not specified or is empty, and the spec.disableNetworkDiagnostics flag in network.operator.openshift.io is set to true, the network diagnostics feature will be disabled. networkType string NetworkType is the plugin that is to be deployed (e.g. OpenShiftSDN). This should match a value that the cluster-network-operator understands, or else no networking will be installed. Currently supported values are: - OpenShiftSDN This field is immutable after installation. serviceNetwork array (string) IP address pool for services. Currently, we only support a single entry here. This field is immutable after installation. serviceNodePortRange string The port range allowed for Services of type NodePort. If not specified, the default of 30000-32767 will be used. Such Services without a NodePort specified will have one automatically allocated from this range. This parameter can be updated after the cluster is installed. 17.1.2. .spec.clusterNetwork Description IP address pool to use for pod IPs. This field is immutable after installation. Type array 17.1.3. .spec.clusterNetwork[] Description ClusterNetworkEntry is a contiguous block of IP addresses from which pod IPs are allocated. Type object Property Type Description cidr string The complete block for pod IPs. hostPrefix integer The size (prefix) of block to allocate to each node. If this field is not used by the plugin, it can be left unset. 17.1.4. .spec.externalIP Description externalIP defines configuration for controllers that affect Service.ExternalIP. If nil, then ExternalIP is not allowed to be set. Type object Property Type Description autoAssignCIDRs array (string) autoAssignCIDRs is a list of CIDRs from which to automatically assign Service.ExternalIP. These are assigned when the service is of type LoadBalancer. In general, this is only useful for bare-metal clusters. In Openshift 3.x, this was misleadingly called "IngressIPs". Automatically assigned External IPs are not affected by any ExternalIPPolicy rules. Currently, only one entry may be provided. policy object policy is a set of restrictions applied to the ExternalIP field. If nil or empty, then ExternalIP is not allowed to be set. 17.1.5. .spec.externalIP.policy Description policy is a set of restrictions applied to the ExternalIP field. If nil or empty, then ExternalIP is not allowed to be set. Type object Property Type Description allowedCIDRs array (string) allowedCIDRs is the list of allowed CIDRs. rejectedCIDRs array (string) rejectedCIDRs is the list of disallowed CIDRs. These take precedence over allowedCIDRs. 17.1.6. .spec.networkDiagnostics Description networkDiagnostics defines network diagnostics configuration. Takes precedence over spec.disableNetworkDiagnostics in network.operator.openshift.io. If networkDiagnostics is not specified or is empty, and the spec.disableNetworkDiagnostics flag in network.operator.openshift.io is set to true, the network diagnostics feature will be disabled. Type object Property Type Description mode string mode controls the network diagnostics mode When omitted, this means the user has no opinion and the platform is left to choose reasonable defaults. These defaults are subject to change over time. The current default is All. sourcePlacement object sourcePlacement controls the scheduling of network diagnostics source deployment See NetworkDiagnosticsSourcePlacement for more details about default values. targetPlacement object targetPlacement controls the scheduling of network diagnostics target daemonset See NetworkDiagnosticsTargetPlacement for more details about default values. 17.1.7. .spec.networkDiagnostics.sourcePlacement Description sourcePlacement controls the scheduling of network diagnostics source deployment See NetworkDiagnosticsSourcePlacement for more details about default values. Type object Property Type Description nodeSelector object (string) nodeSelector is the node selector applied to network diagnostics components When omitted, this means the user has no opinion and the platform is left to choose reasonable defaults. These defaults are subject to change over time. The current default is kubernetes.io/os: linux . tolerations array tolerations is a list of tolerations applied to network diagnostics components When omitted, this means the user has no opinion and the platform is left to choose reasonable defaults. These defaults are subject to change over time. The current default is an empty list. tolerations[] object The pod this Toleration is attached to tolerates any taint that matches the triple <key,value,effect> using the matching operator <operator>. 17.1.8. .spec.networkDiagnostics.sourcePlacement.tolerations Description tolerations is a list of tolerations applied to network diagnostics components When omitted, this means the user has no opinion and the platform is left to choose reasonable defaults. These defaults are subject to change over time. The current default is an empty list. Type array 17.1.9. .spec.networkDiagnostics.sourcePlacement.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. 17.1.10. .spec.networkDiagnostics.targetPlacement Description targetPlacement controls the scheduling of network diagnostics target daemonset See NetworkDiagnosticsTargetPlacement for more details about default values. Type object Property Type Description nodeSelector object (string) nodeSelector is the node selector applied to network diagnostics components When omitted, this means the user has no opinion and the platform is left to choose reasonable defaults. These defaults are subject to change over time. The current default is kubernetes.io/os: linux . tolerations array tolerations is a list of tolerations applied to network diagnostics components When omitted, this means the user has no opinion and the platform is left to choose reasonable defaults. These defaults are subject to change over time. The current default is - operator: "Exists" which means that all taints are tolerated. tolerations[] object The pod this Toleration is attached to tolerates any taint that matches the triple <key,value,effect> using the matching operator <operator>. 17.1.11. .spec.networkDiagnostics.targetPlacement.tolerations Description tolerations is a list of tolerations applied to network diagnostics components When omitted, this means the user has no opinion and the platform is left to choose reasonable defaults. These defaults are subject to change over time. The current default is - operator: "Exists" which means that all taints are tolerated.

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. 17.1.13. .status Description status holds observed values from the cluster. They may not be overridden. Type object Property Type Description clusterNetwork array IP address pool to use for pod IPs. clusterNetwork[] object ClusterNetworkEntry is a contiguous block of IP addresses from which pod IPs are allocated. clusterNetworkMTU integer ClusterNetworkMTU is the MTU for inter-pod networking. conditions array conditions represents the observations of a network.config current state. Known .status.conditions.type are: "NetworkTypeMigrationInProgress", "NetworkTypeMigrationMTUReady", "NetworkTypeMigrationTargetCNIAvailable", "NetworkTypeMigrationTargetCNIInUse", "NetworkTypeMigrationOriginalCNIPurged" and "NetworkDiagnosticsAvailable" conditions[] object Condition contains details for one aspect of the current state of this API Resource. --- This struct is intended for direct use as an array at the field path .status.conditions. For example, type FooStatus struct{ // Represents the observations of a foo's current state. // Known .status.conditions.type are: "Available", "Progressing", and "Degraded" // +patchMergeKey=type // +patchStrategy=merge // +listType=map // +listMapKey=type Conditions []metav1.Condition json:"conditions,omitempty" patchStrategy:"merge" patchMergeKey:"type" protobuf:"bytes,1,rep,name=conditions" // other fields } migration object Migration contains the cluster network migration configuration. networkType string NetworkType is the plugin that is deployed (e.g. OpenShiftSDN). serviceNetwork array (string) IP address pool for services. Currently, we only support a single entry here. 17.1.14. .status.clusterNetwork Description IP address pool to use for pod IPs. Type array 17.1.15. .status.clusterNetwork[] Description ClusterNetworkEntry is a contiguous block of IP addresses from which pod IPs are allocated. Type object Property Type Description cidr string The complete block for pod IPs. hostPrefix integer The size (prefix) of block to allocate to each node. If this field is not used by the plugin, it can be left unset. 17.1.16. .status.conditions Description conditions represents the observations of a network.config current state. Known .status.conditions.type are: "NetworkTypeMigrationInProgress", "NetworkTypeMigrationMTUReady", "NetworkTypeMigrationTargetCNIAvailable", "NetworkTypeMigrationTargetCNIInUse", "NetworkTypeMigrationOriginalCNIPurged" and "NetworkDiagnosticsAvailable" Type array 17.1.17. .status.conditions[] Description Condition contains details for one aspect of the current state of this API Resource. --- This struct is intended for direct use as an array at the field path .status.conditions.

This should be when the underlying condition changed. If that is not known, then using the time when the API field changed is acceptable. message string message is a human readable message indicating details about the transition. This may be an empty string. observedGeneration integer observedGeneration represents the .metadata.generation that the condition was set based upon. For instance, if .metadata.generation is currently 12, but the .status.conditions[x].observedGeneration is 9, the condition is out of date with respect to the current state of the instance. reason string reason contains a programmatic identifier indicating the reason for the condition's last transition. Producers of specific condition types may define expected values and meanings for this field, and whether the values are considered a guaranteed API. The value should be a CamelCase string. This field may not be empty. status string status of the condition, one of True, False, Unknown. type string type of condition in CamelCase or in foo.example.com/CamelCase. --- Many .condition.type values are consistent across resources like Available, but because arbitrary conditions can be useful (see .node.status.conditions), the ability to deconflict is important. The regex it matches is (dns1123SubdomainFmt/)?(qualifiedNameFmt) 17.1.18. .status.migration Description Migration contains the cluster network migration configuration.
