In the procedure from the above link we give 2 examples for creating CRD and then we apply the examples. The thing is that we don't specify the filename to create in the examples and we expect the user to assume that we worked with what we apply.

The 2 examples I refer to are:

oc apply -f secretseedgenerator.yaml

oc apply -f seedgenerator.yaml
