Currently failing with:

        location = self._get_python_dir() / "omeroweb"                                                                                  web_1     | OSError: [Errno 13] Permission denied: '/opt/omero/web/venv/lib/python2.7/site-packages/omeroweb/static'

Does setting omero.web.static_root/STATIC_ROOT fix this?
https://github.com/ome/omero-web/blob/d176ac3a833dbec2d55afa3eece6a810820c6922/omeroweb/settings.py#L423-L430

[joshmoore]

What do we want the new value to be? Keep it in lib/python? Under var/? Calculate from OMERODIR?

[joshmoore]

Note: STATIC_ROOT (from docker-compose) does not work but omero.web.static_root does.

[manics]

var sounds good, is the whole /var directory being moved to a read-write location?

[joshmoore]

Eventually, I'd think so.

Haven't tested yet, but proposing to push this:

    Place static files under var/static

This will need work with Simon's post-omego world.
