Description Sam Batschelet 2020-03-31 23:14:46 UTC
Description of problem: configmaps for the etcd-ca-bundle is populated with a default value. The result is CVO will rewrite the invalid config map data "stub" and cause other controllers in the operator to sync adding overhead to the cluster and in some cases could result in failed client calls to etcd by the operator. These calls could result in invalid event data. For example if a call to status failed we would consider the member unhealthy.

Version-Release number of selected component (if applicable):

How reproducible: always

Steps to Reproduce:

Actual results:

Expected results: CVO to create the configmap resource once and not overwrite it.
