Possibility to set UID and GID of omero-server user

[tstoeter]

Is there a possibility for the omero server container to set the UID and GID of the omero-server user, i.e. to respect the user setting from the docker-compose.yml?

  ...
  omeroserver:
    # This container uses the tag for the latest server release of OMERO 5
    # To upgrade to the next major release, increment the major version number
    image: "openmicroscopy/omero-server:5"
    user: 1234:2468
    environment:
      CONFIG_omero_db_host: database
      CONFIG_omero_db_user: omero
    ...

This would facilitate managing permissions of bind mounts for data storage on the host, e.g. having /OMERO on the host file system.

Currently, the omero-server user has 1000:992 as fixed UID:GID.

It's possible, but may require some coordination with assumptions in the upstream repositories.

https://github.com/search?q=repo%3Aome%2Fomero-server-docker%201000&type=code for example says that you also need to tell the ansible playbook which UID to use.

https://github.com/ome/omero-test-infra/blob/cda3ec65052d6933052c8683d080677c6c33dc73/docker#L267 looks to have a hard-coding as well, but that's less critical.
