prefix docker containers names

User Story

I cookiecut two instances and I want to run them both depending on which project I am working on.

Current result

The second docker-compose up will fail (containers already exist). This containers will need to be removed and recreated for the second project, because the ./scripts/setup will get denied in the DB (wrong credentials).

Expected result

I understand the services should be independent, but I don't want to have to change defaults of rabbit/redis/db/es for each instance. However, if the containers names(?) are prefixed with e.g. instance name this would not happen. The second docker-compose up would not fail and both could co-exist.

Possible drawback

End up with 20k services running, but is up to each one of us to control that I guess.

You want them both running at the same time? Would you just get port conflicts?

True on the ports, but then if stopped, when creating the new ones, the name would still collide no?
