I haven't tried it yet with Docker, but I'm starting a networking service (pretty much SoftEther as a service) that might work on your case. The idea is that your Docker containers will connect to a central server (443/TCP outgoing traffic) and have a virtual private network among them through this "hub", so they've got full access to each other. This is a layer 2 network and in my offering I have DHCP running by default to simplify things (100.64.0.0/24... naughty, I know :)). The communications are encrypted, so effectively you've got a sort of Virtual Private Network between your containers. As I said, I haven't tried yet with Docker, but it's worth a shot. My service simplifies the process of getting up and running. https://wormhole.network https://wormhole.network
