Hostname for taskmanagers when running in docker

[Nikola Hrusov]

Hello,

After upgrading the docker image for flink to 1.11.1 from 1.9 the hostname
of the taskmanagers reported to our metrics show as IPs (e.g. 10.0.23.101)
instead of hostnames.

In the docker compose file we specify the hostname as such:


*hostname: "taskmanager-{{ '{{' }}.Node.Hostname{{ '}}' }}"*

Is there another way of achieving this?

Regards
