If I want to use a static IP for my container I must declare my own network and start the container with --net mynet0 --ip 172.16.0.2.

Why is it not possible to use a static IP address within the docker deafult bridge? Why so cumbersome making me create a new network?

  • It's a bit confusing. You have IP assigned to the bridge and you expect, that the same IP could be used in the container too? – Jaroslav Kucera Dec 12 '17 at 17:46
  • Yeah ok, sorry for that: I want to have a static IPs in the default Bridge and that's not possible. But I can only use static IPs within an user-defined network. A static IP within the default Bridge, that's what I want. – chevallier Dec 12 '17 at 20:22

you can set a default bridge ip by either editing /etc/docker/daemon.json or starting the daemon with flag --bip=<ip>/<cidr>

  • Sorry man I'm not talking about a default bridge IP, I'm talking about a static IP for a container in the default bridge. – chevallier Dec 16 '17 at 13:47
