dockerproxy usage best practice?

[akabyshev]

I have a suggestion about a sample docker-compose shown at /configs/docker/#using-docker-socket-proxy:

  ports:
    - 127.0.0.1:2375:2375

Since two containers are isolated within a dedicated network, this particular port mapping is not necessary for inter-container communications to function. There is a concern that an inexperienced or inattentive user could inadvertently expose port 2375 on the host if the "127.0.0.1:" segment is lost at some point.

And we all know that kind of errors happen. For example, Portainer does not preserve the "127.0.0.1" portion of the binding when using the "Duplicate/Edit" feature.

Thanks!

Whoops, it seems I was under the impression that that compose.yml declares a network for those 2 containers

It seems I'm that inattentive user right now
