Allow setting UID/GID of user about ansible-role-omero-web

[manics]

What changes are required that can't be handled by docker run --user UID?

[joshmoore]

That doesn't change the UID/GID of the files owned by that user, right? The goal in that thread is to be able to access the source file to develop on omero-web. The docker cp workflow there would need this change. Other ideas welcome.

A host directory is being mounted on /opt/omero/web, which means the permissions and UID should be entirely determined by the host system.

[joshmoore]

I don't follow. The goal of using docker cp was to have a simple way to get the valid values out for editing. However, docker cp transforms permissions even when using -a. Another option would be to have all of /opt/omero/web in a volume, but that's not currently the case. The downstream dockerfile that I added on that forum post does the trick, but it's suboptimal.

If the primary goal is development I'd have though it'd be easier to download OMERO.py on the host, mount that on /opt/omero/web/OMERO.web, run the docker container with your local UID, and make changes on your host, bypassing the need to copy files back and forth.

edit: what would be even nicer is if you could git clone https://github.com/openmicroscopy/openmicroscopy locally and mount a subdir of that on /opt/omero/web/OMERO.web

The difference between docker cp and wget OMERO.py is probably negligible, so whatever works.

More critical is going to be getting the UIDs/GIDs correct which is what this card is about. I tried several things (all on that thread) with only the last working and it would be simplified by being able to change the UID in the build without needing to chown. If you have another working blurb that doesn't require it, 👍

Not exactly the same, but at least for the OMERO.server image there's now https://github.com/openmicroscopy/openmicroscopy/pull/5656/files#diff-3254677a7917c6c01f55212f86c57fbf
