+++ This bug was initially created as a clone of Bug #1798135 +++ Description of problem: In a long-running cluster, I noticed that newly deployed CatalogSource objects were not being reconciled at all. After some digging, I found the following in the catalog-operator pod logs: $ oc logs catalog-operator-754858b4d7-gphgx -n openshift-operator-lifecycle-manager time="2020-01-20T17:43:28Z" level=info msg="log level info" time="2020-01-20T17:43:28Z" level=info msg="TLS keys set, using https for metrics" time="2020-01-20T17:43:28Z" level=info msg="Using in-cluster kube client config" time="2020-01-20T17:43:28Z" level=info msg="Using in-cluster kube client config" time="2020-01-20T17:43:28Z" level=info msg="Using in-cluster kube client config" time="2020-01-20T17:43:28Z" level=info msg="operator not ready: communicating with server failed: Get https://172.30.0.1:443/version?timeout=32s: dial tcp 172.30.0.1:443: connect: connection refused" Version-Release number of selected component (if applicable): Observed on a 4.2.14 cluster How reproducible: This only happens if there's an issue contacting the Kubernetes api servers when the catalog operator pod boots. If there is an issue, the error handling logic in the pod has a gap today where the pod still reports as healthy, the pod continues to run, but it never retries contacting the kubernetes api server nor does it ever start reconciling OLM objects. Something around https://github.com/operator-framework/operator-lifecycle-manager/blob/7d6665d6585a733356c2fbc0919a047de244f59b/pkg/lib/queueinformer/queueinformer_operator.go#L193 is where the logic is letting things get in this hung state. Steps to Reproduce: I'm not sure how easy it will be to reproduce this on-demand. An error contacting the K8s api server needs to happen when the pod boots. An integration or unit test in the code of the catalog operator should be able to reproduce this at all, but that's not quite the same as reproducing it in a live cluster. Actual results: The catalog operator pod stays running but does not do its job. Once it gets in this state, no OLM objects managed by this operator get reconciled and thus new CatalogSources and such do not work. Expected results: The catalog operator pod should be able to recover from a failure contacting the kuberntes api server. Additional info:
