------------------------------------
Summary: Setting the TTL for discarding task pods on Kubernetes.
Key: FLINK-16288
URL: https://issues.apache.org/jira/browse/FLINK-16288
Project: Flink
Issue Type: Improvement
Components: Deployment / Kubernetes
Affects Versions: 1.10.0
Reporter: Niels Basjes
I'm experimenting with running Flink 1.10.0 on native Kubernetes (version 1.17).
After a job ends the task pods that were used to run it are discarded quite
quickly.
I found that if my job goes wrong I have too little time to look at all of the
logs.
I propose having a new config setting that allows me to run Flink on k8s where
I can set the minimum time before an idle task pod is discarded.
That way I can start Flink with a pod ttl of an hour (or something like that)
so I have enough time to go through the logs and figure out what I did wrong.
