Remove docker0 bridge

Question

I'm using docker via

# service docker start

This creates a docker0 bridge. However using

# service docker stop

doesn't remove this bridge.

How do I get rid of it? I'm not sure if I missed something here.

Just delete it:

ip link del docker0

(The old way, specific to bridges: brctl delbr docker0)

That was step one, but the `NetworkManager` still had the bridge. So calling `nmcli connection delete docker0` resolved the issue completely. – tynn Nov 03 '15 at 12:11
Thanks for the note @tynn, definitely useful when developing from a system with a GUI. – dragon788 Apr 02 '16 at 00:17

Will this solution prevent Docker from starting correctly after doing `service docker start` or will docker create the bridge again? – AlikElzin-kilaka May 14 '17 at 12:05
This is not an old way, you still need brctl package to do any bridges process. – Mohammed Noureldin Jul 15 '17 at 02:00

No you don't. iproute2 is perfectly capable of doing the same. – u1686_grawity Jul 15 '17 at 07:46

@AlikElzin-kilaka the bridge is created again when you start docker – Fabian Schmengler Oct 19 '18 at 06:21

For the googlers: Check command `docker network ls` and `docker network rm `. The ID is the same as in the br- or bridge name! – uav Jan 09 '20 at 18:54
