Interesting. I suggest you pass the MONGOID_AUTH_MECH
environment variable to the forum container. You can do this by defining a custom docker-compose.override.yml
file:
$ cat "$(tutor config printroot)/env/local/docker-compose.override.yml"
version: "3.7"
services:
forum:
environment:
- "MONGOID_AUTH_MECH=:scram"
