+++ This bug was initially created as a clone of Bug #1883461 +++ k8s.io/klog moved to v2 in client-go and frieds. The operator does not use v2 yet and hence, we lose one half of the logging output (v2). --- Additional comment from Stefan Schimanski on 2020-09-29 11:09:06 UTC --- I did some tests using openshift-apiserver that uses kube component-base to add klog command line flags: $ ./openshift-apiserver start --config asfd --v=4 I0929 13:04:18.354425 53628 cmd.go:57] v1 klog I0929 13:04:18.354506 53628 cmd.go:58] v2 klog I0929 13:04:18.354512 53628 cmd.go:61] v2 V(2) klog I0929 13:04:18.354515 53628 cmd.go:64] v2 V(4) klog So this means that we DO NOT set verbosity for v1 klog, and hence lose all the klogv1.V(2).Infof output.
Affects both openshift-controller-manager and cluster-openshift-controller-manager-operator
Now ocm-o and ocm are using v2 klog, so verified it.
