OCPBUGS-2793: deployment - remove unsolicited containers #188

Closed alebedev87 closed 1 year ago

alebedev87 commented 1 year ago

Previous PR for the same ticket introduced a new bug: unsolicited containers from the previous states of ExternalDNS CR are kept. The bug was caught by @lihongan and has this visible consequence when the zone ID (ExternalDNS.spec.zones) of an existing instance of ExternalDNS is changed.

Bad case scenario:

Impact:

Solution: At first the idea was to discard the containers from the previous state judging by their name (external-dns-<hash>). However the idea of being stricter until a real use case comes up dominated. So all the unsolicited containers are now removed from the managed deployment.

e2e-infoblox-operator failed because the cluster had no worker nodes. In the machine-api-controllers pod logs, I see the following being logged repeatedly:

E1208 21:51:02.230090       1 controller.go:297] ci-op-4zky13qb-74059-5q55r-worker-a-w6tkj: failed to check if machine exists: ci-op-4zky13qb-74059-5q55r-worker-a-w6tkj: failed to create scope for machine: error getting credentials secret "gcp-cloud-credentials" in namespace "openshift-machine-api": Secret "gcp-cloud-credentials" not found

In credentialsrequests.json, I found the following:

                        "message": "failed to grant creds: error syncing creds in mint-mode: error creating custom role: rpc error: code = ResourceExhausted desc = Maximum number of roles reached. Maximum is: 300\nerror details: retry in 24h0m1s",

e2e-gcp-operator failed, evidently for the same reason—I see the same error in credentialsrequests.json for e2e-gcp-operator as well.
