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}}
