Aha, inside the docker I can see

[root@26afd7f0f17d linux]# cd /var/spool/cron/
[root@26afd7f0f17d cron]#

which seems to be a result of your changes (cron job)

today's java version is

[root@26afd7f0f17d cron]# java --version

I am still confused about: Whilst being inside the docker, how do I activate the omero-server venv to be able to run cmds like omero admin diagnostics ?

[jburel]

in the docker container, you will see under /home/omero/workspace/OMERO-server a virtual environment .venv3, activate that virtual environment then you can access the omero commands
