I just got this working with a web_only container, a data container, and nginx-proxy in front, all on the same user-defined network.
With the web_only template, the network needs to be specified in the user args on the command line because at least one of the lines that runs the base docker image does not include $docker_args, while that line does include $user_args.
Like: ./launcher rebuild web_only --docker-args '--network nginx-proxy'
I also had that set in docker_args: in web_only.yml:
docker_args:
- '--network nginx-proxy'
I know this is an old topic, but google brought me here, and google knows all.
@mpalmer would it be not good to include $docker_args on L640?
