Broken dockerization

[HerrNaN]

Running docker-compose up --build results in the following:

E: Some index files failed to download. They have been ignored, or old ones used instead.
ERROR: Service 'web' failed to build: The command '/bin/sh -c apt-get update && apt-get install -y net-tools nodejs' returned a non-zero code: 100

This seems to indicate that the docker file is deprecated and should probably be updated

@malmers @lindskogen @gurr1 any ideas?

docker-library/ruby@5d977ba
Remove Ruby 2.3 (EOL)

Maybe we can try to upgrade ruby version?
