# this is a super hacky workaround for https://github.com/kubernetes/kubernetes/issues/91395
# which a result of fixing the validation on CRD objects. The validation ensures the fields that are list map keys, are either marked
# as required or have default values to ensure merging of list map items work as expected.
# With "containerPort" and "protocol" being considered as x-kubernetes-list-map-keys in the container ports, and "protocol" was not
# a required field, the CRD would fail validation with errors similar to the one reported in https://github.com/kubernetes/kubernetes/issues/91395.
# once controller-gen (above) is able to generate CRDs with `protocol` as a required field, this hack can be removed.
