You can configure operator deployed by OLM using Subscription Config. This will be handy for cluster administrators if there is a need to tweak the operator deployment based on cluster state. For example, you can update resource requests/limits of an OOMKilled
operator pod, add a nodeSelector
for operator, etc.
