Does the Helm files work?

[borah-hemanga]

Hey Guys,
Do the helm files distributed with the package work?

I installed the operator with the helm files described here: https://github.com/spotify/flink-on-k8s-operator/tree/master/helm-chart/flink-operator.

And then I try to create a Flink cluster to create a Beam application using this command as described in the user guide:
kubectl apply -f config/samples/flinkoperator_v1beta1_flinksessioncluster.yaml

I see the following error:

I also noticed that there is a difference between the contents of the helm folder in the zip file and the yaml file in the distributions here:

https://github.com/spotify/flink-on-k8s-operator/releases/tag/v0.4.0-beta.7

For example,

• the certs and webhooks are created using scripts in config for the zip files, but are direct configurations for the flink-operator.yaml file.
• there is a job defined for the certificates for the zip files, which does not exist for the yaml
• there is a discrepancy in the crd definition as well

Hello @borah-hemanga!

To be honest we don't use really rely on the helm-charts and they do need some work/refactor! Open to accept contributions 😄
