apiVersion of template is ignored

[toabi]

Describe the bug
I'm creating mongodb instances for percona mongodb operator. For the operator it looks like a v1 CRD and things fail because the rest of the setup is made for v1-4-0.

I'm not 100% sure if the fault lies with couchbase-sb or percona for having weird version names. (I never saw them with dashes).

Here's the code for their finding-out-the-version magic https://github.com/percona/percona-server-mongodb-operator/blob/d8c30cba10f33aea2d6a21b19a78deb8accdc420/pkg/apis/psmdb/v1/psmdb_types.go#L471

To Reproduce
It's a bit complex, but in general you install the psmdb operator and use this service-broker to create a cluster crd.

Expected behavior
CRD in version 1-4-0 is created.

Workaround
Used kubectl edit on the crd to set it to 1-4-0 and then things started to work again.

Environment (please complete the following information):

• Kubernetes Version: 1.17-EKS
• Service Broker Version: master

More info

That's the template configured in the service broker

Wow, that is magnificently crap 😸 In your template try:

metadata:
  annotations:
    kubectl.kubernetes.io/last-applied-configuration: '{"apiVersion":"psmdb.percona.com/v1-4-0"}' 

[spjmurray]

Obviously they are trying to tell you it can only be installed with kubectl apply...

[toabi]

Yep, that's really weird to handle CRD. The quickfix with the "behaves-like-kubectl"-annotation works 🥳 - so actually this isn't really a bug here and this can be closed.

If there is a bug, it's that percona should be using v1beta14 to do versioning, that would work.
