We are getting same issue with Helm Installation also:

Steps:

1. git clone https://github.com/GoogleCloudPlatform/flink-on-k8s-operator.git
2. cd flink-on-k8s-operator
3. helm install -g  ./helm-chart/flink-operator/ --set operatorImage.name=gcr.io/flink-operator/flink-operator:latest

See: #311

Able to deploy the Operator by adding below as mentioned in #311

We added protocol as mentioned in the error.

                        required:
                          - containerPort
                          - protocol

File Path: helm-chart/flink-operator/templates/flink-cluster-crd.yaml

Note: Make sure you put this at right place.

Thank you @EnriqueL8 for pointing to the correct issue.
