intercom/nginx-proxy repository overview

The upstream image of jwilder/nginx-proxy⁠, but with the additional feature that the container will alias host.docker.internal⁠ to resolve to the host machine on Linux machines as well. It does this by first attempting to resolve the standard alias in an entrypoint script - if it can be resolved, it doesn't change anything. If we cannot resolve it, we're probably on a Linux host and proceed to use the default gateway as the host IP.
