Crowdsec metabase setup error "unable to find 'groupadd' command"

I am trying to set up the metabase dashboard for crowdsec running inside a docker container. I have given it access to the docker socket, by bind mounting it, but it attempts to create the crowdsec group and fails, as the command is unavailable inside the docker container. So is this feature unsupported or broken for the docker version of crowdsec, or is there any workaround to still get it working?

Yes, we have explicit stated that running cscli dashboard inside a docker container is not supported as there too much stuff to get working (container layers) plus it will be deprecated in version 1.7.0.

The way to do it is to build a custom metabase image and use it within the compose:
