Many people don't realize this, but Docker has a pretty good, and very simple JSON API.<p>Not only can you connect from anywhere with the docker client, but you can also use any other HTTP(s) speaking tool including curl or even your browser directly.<p>TLS certificate authentication is supported by the docker daemon by default (it's a flag away), and using that is a lot more secure than using an unauthenticated web UI like this, which is dangerously close to giving root access to your server to anyone who can route to your port.
