Mind having a look, please, @egarriga ? You can look at the "Build" section in the docker/README.md file for an example how to build it. That should produce a local image that you can test with something like docker run --rm -ti kinow/autosubmit:4.1.9-bullseye-slim /bin/bash (replacing kinow by your OS $USER).
Once we merge this, I will then build it again using master, and upload it to DockerHub. And at some point will update the PostgreSQL merge request to rebase and fix conflicts (i.e. this merge request will simplify the postgres merge request too).
Cheers
