There are a lot of problems to solve here, and when the recent motion in Docker networking / plugins model settles down a bit and a solution gets merged into Docker proper, it will make inter-container communication across hosts easier. > Will Machine handle configuring firewalls, SSL, SSH keys and all that jazz across hosts so containers can reach each other? I've automated a lot of this myself but would love something that does it for you We definitely want to make the lives of operators a lot easier. It's still early days for figuring out the scope other than "let's make a tool to get a lot of Docker daemons, in a very straightforward way", so we'd really love to have you get involved and give your feedback! It handles some SSH key / TLS cert management right now, but there's a huge surface area of things we need to consider carefully.
