The downside with choosing the "first address" is that in the case of a docker network overlay, the first ip will likely be the wrong one. It would be better if it would bind to all ip's on a given interface, if you don't want it to bind to all of them then the ip should be specified. Perhaps something like: --bind eth0 to bind to all ip's on a given interface --bind eth0;10.0.0.0/16 bind to any ip on a given interface that matches the given cidr. --bind eth0;10.0.0.5 bind to a specific ip on a given interface --bind 10.0.0.5 bind to a specific ip regardless of interface --bind 10.0.0.0/16 bind to a given ip that matches a cidr regardless of interface
