Inject additional volumes on operator level

[stephan2012]

Please, answer some short questions which should help us to understand your problem / question better?

• Which image of the operator are you using? registry.opensource.zalan.do/acid/postgres-operator:v1.6.3
• Where do you run it - cloud or metal? Kubernetes or OpenShift? Bare Metal K8s
• Are you running Postgres Operator in production? yes
• Type of issue? [Bug report, question, feature request, etc.] Question/Feature Request

In case I did not overlook anything it is currently possible to add additional volumes through the additionalVolumes attribute in the postgresql cluster object but not globally. My use-case is to provide additional certificates to all clusters, and for that it would be helpful to configure additional volumes on the operator level similar to sidecars.

I’d appreciate a pointer to the docs if this feature exists already.

Just discovered another use-case: I need to mount a ConfigMap to a sidecar container that shall be present on all database clusters.

Edit: Sorry, didn't read enough documentation. My case should be possible with additionalVolumes.
