Since this should be a fairly basic operator, there probably won't be much in the CRD. The CRD is the thing that the Operator will watch and act upon.

I think the integreatly team have recently created an operator for their webapp, so it might be interesting to see what that has (it could be the thing that's most like this). See example: https://github.com/integr8ly/tutorial-web-app-operator/blob/master/deploy/crd.yaml
