The last time I tried to use that it failed when coupling containers. Ie that nginx requires, my web app, which requires the database. Every process but the database failed because they all depended on each other. I ended up using shell scripts which used an arbitrary wait of 2 seconds after each process. that fixed the problem so that the containers came up after a reboot. Did docker fix that yet?
I think the implementation of links between containers did change significantly in the past year and a half.
But that "links break when containers restart or are replaced" aspect was a deal-breaker for me when I started using docker "near production". I just use --net=host ... so I don't use docker network-related functionality at all. For my purposes server-level firewall settings are fine.
