It turns out that the latest flink:latest docker image is 5 days old, and thus bug was fixed 4 days ago in the flink-docker github.
The problem is that the docker-entrypoint.sh script chains to jobmanager.sh by saying "start-foreground cluster" where the "cluster" argument is obsolete as of Flink 1.5. I patched it with a sed command in the Kubernetes manifest, until the updated docker image makes it way to the world. -- Sent from: http://apache-flink-user-mailing-list-archive.2336050.n4.nabble.com/
