Chapter 10. EgressRouter [network.operator.openshift.io/v1] Description EgressRouter is a feature allowing the user to define an egress router that acts as a bridge between pods and external systems. The egress router runs a service that redirects egress traffic originating from a pod or a group of pods to a remote external system or multiple destinations as per configuration. It is consumed by the cluster-network-operator. More specifically, given an EgressRouter CR with <name>, the CNO will create and manage: - A service called <name> - An egress pod called <name> - A NAD called <name> Compatibility level 1: Stable within a major release for a minimum of 12 months or 3 minor releases (whichever is longer). EgressRouter is a single egressrouter pod configuration object. Type object Required spec 10.1. 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#metadata spec object Specification of the desired egress router. status object Observed status of EgressRouter. 10.1.1. .spec Description Specification of the desired egress router. Type object Required addresses mode networkInterface Property Type Description addresses array List of IP addresses to configure on the pod's secondary interface. addresses[] object EgressRouterAddress contains a pair of IP CIDR and gateway to be configured on the router's interface mode string Mode depicts the mode that is used for the egress router. The default mode is "Redirect" and is the only supported mode currently. networkInterface object Specification of interface to create/use. The default is macvlan. Currently only macvlan is supported. redirect object Redirect represents the configuration parameters specific to redirect mode. 10.1.2. .spec.addresses Description List of IP addresses to configure on the pod's secondary interface. Type array 10.1.3. .spec.addresses[] Description EgressRouterAddress contains a pair of IP CIDR and gateway to be configured on the router's interface Type object Required ip Property Type Description gateway string IP address of the -hop gateway, if it cannot be automatically determined. Can be IPv4 or IPv6. ip string IP is the address to configure on the router's interface. Can be IPv4 or IPv6. 10.1.4. .spec.networkInterface Description Specification of interface to create/use. The default is macvlan. Currently only macvlan is supported. Type object Property Type Description macvlan object Arguments specific to the interfaceType macvlan 10.1.5. .spec.networkInterface.macvlan Description Arguments specific to the interfaceType macvlan Type object Required mode Property Type Description master string Name of the master interface. Need not be specified if it can be inferred from the IP address. mode string Mode depicts the mode that is used for the macvlan interface; one of Bridge|Private|VEPA|Passthru. The default mode is "Bridge". 10.1.6. .spec.redirect Description Redirect represents the configuration parameters specific to redirect mode. Type object Property Type Description fallbackIP string FallbackIP specifies the remote destination's IP address. Can be IPv4 or IPv6. If no redirect rules are specified, all traffic from the router are redirected to this IP. If redirect rules are specified, then any connections on any other port (undefined in the rules) on the router will be redirected to this IP. If redirect rules are specified and no fallback IP is provided, connections on other ports will simply be rejected. redirectRules array List of L4RedirectRules that define the DNAT redirection from the pod to the destination in redirect mode. redirectRules[] object L4RedirectRule defines a DNAT redirection from a given port to a destination IP and port. 10.1.7. .spec.redirect.redirectRules Description List of L4RedirectRules that define the DNAT redirection from the pod to the destination in redirect mode. Type array 10.1.8. .spec.redirect.redirectRules[] Description L4RedirectRule defines a DNAT redirection from a given port to a destination IP and port. Type object Required destinationIP port protocol Property Type Description destinationIP string IP specifies the remote destination's IP address. Can be IPv4 or IPv6. port integer Port is the port number to which clients should send traffic to be redirected. protocol string Protocol can be TCP, SCTP or UDP. targetPort integer TargetPort allows specifying the port number on the remote destination to which the traffic gets redirected to. If unspecified, the value from "Port" is used. 10.1.9. .status Description Observed status of EgressRouter. Type object Required conditions Property Type Description conditions array Observed status of the egress router conditions[] object EgressRouterStatusCondition represents the state of the egress router's managed and monitored components. 10.1.10. .status.conditions Description Observed status of the egress router Type array 10.1.11. .status.conditions[] Description EgressRouterStatusCondition represents the state of the egress router's managed and monitored components. Type object Required status type Property Type Description lastTransitionTime `` LastTransitionTime is the time of the last update to the current status property. message string Message provides additional information about the current condition. This is only to be consumed by humans. It may contain Line Feed characters (U+000A), which should be rendered as new lines. reason string Reason is the CamelCase reason for the condition's current status. status string Status of the condition, one of True, False, Unknown. type string Type specifies the aspect reported by this condition; one of Available, Progressing, Degraded 10.2.
