Chapter 12. 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.

| When present, indicates that modifications should not be persisted. An invalid or unrecognized dryRun directive will result in an error response and no further processing of the request. Valid values are: - All: all dry run stages will be processed |
|
| fieldValidation instructs the server on how to handle objects in the request (POST/PUT/PATCH) containing unknown or duplicate fields. Valid values are: - Ignore: This will ignore any unknown fields that are silently dropped from the object, and will ignore all but the last duplicate field that the decoder encounters. This is the default behavior prior to v1.23. - Warn: This will send a warning via the standard warning response header for each unknown field that is dropped from the object, and for each duplicate field that is encountered. The request will still succeed if there are no other errors, and will only persist the last of any duplicate fields. This is the default in v1.23+ - Strict: This will fail the request with a BadRequest error if any unknown fields would be dropped from the object, or if any duplicate fields are present. The error returned from the server will contain all unknown and duplicate fields encountered. |
