[jira] [Created] (FLINK-22262) Flink on Kubernetes ConfigMaps are created without OwnerReference

Andrea Peruffo created FLINK-22262:
--------------------------------------

             Summary: Flink on Kubernetes ConfigMaps are created without OwnerReference
                 Key: FLINK-22262
                 URL: https://issues.apache.org/jira/browse/FLINK-22262
             Project: Flink
          Issue Type: Bug
    Affects Versions: 1.13.0
            Reporter: Andrea Peruffo


According to the documentation:
[https://ci.apache.org/projects/flink/flink-docs-master/docs/deployment/resource-providers/native_kubernetes/#manual-resource-cleanup]

The ConfigMaps created along with the Flink deployment is supposed to have an OwnerReference pointing to the Deployment itself, unfortunately, this doesn't happen and causes all sorts of issues when the classpath and the jars of the job are updated.
i.e.:
Without manually removing the ConfigMap of the Job I cannot update the Jars of the Job.

Can you please give guidance if there are additional caveats on manually removing the ConfigMap? Any other workaround that can be used?

Thanks in advance.

Example ConfigMap:

{{apiVersion: v1}}
{{data:}}
{{ address: akka.tcp://flink@10.0.2.13:6123/user/rpc/jobmanager_2}}
