Expected Behavior

Vault configurer is up and running, accepting vault_cr labeled config maps and kv v2 at platform/secrets is eventually created.

Actual Behavior

No vault configurer is deployed, nothing listens for config maps and no errors or warnings are reported anywhere.

Steps To Reproduce

Start any cluster
Deploy operator (SA is customized to vault-root), namespace - security-vault
kubectl apply provided yaml (note missing externalConfig field!)

Logs

None. And that is an issue in itself.

Additional Information

This check is frustratingly difficult to figure out and debug. It is poorly documented and is very questionable why such behavior even exists.

Motivation: by default one would expect that not providing any externalConfig in vault CR would leave one with working vault instance that can be further customized in a decoupled way via config maps. But that assumption is incorrect and it is not documented (whole vault_cr stuff is really can be figured out through digging through examples, but that is another issue entirely) anywhere.
