[FB] The recommended java container should be Tomcat. If you are going to
work on PR the best approach would be you start from the current repo
geoserver-docker

[FB] I've the impression here that an optimal solution would be to keep
separate dev and prod setup which means we might create an unique repo for
the prod one where GeoNode is managed as a library (relying on stable pip
versions) so we can address also geonode-project under the Ariel's vision
and keep a docker-compose for dev on the geonode repo as it is now.

- See if there's a way to run the integration tests on the docker-compose

[FB] This should be very important imho and at least should cover minimal
use cases like the basic functionalities you mentioned above

[FB] If working on a PR my general suggestion would be to accommodate your
work as much as possible with that already in place under the *-docker
repos on the Geonode github organization
