How to change the default IP address of docker bridge adapter

Question

Hi Guys,

I am new in docker. Whenever I launched a container it gets ip from bridge adapter and the default gateway is 172.17.0.1/16. But I want to change the default gateway address. How can I do that?

Hi@akhtar,

You can reconfigure the default bridge network by providing the bip option along with the desired subnet in the daemon.json (default location at /etc/docker/daemon.json ) file as follows.

$ vim /etc/docker/daemon.json
{
  "bip": "172.200.0.1/16"
}

Then restart the docker daemon as root.

$ systemctl restart docker

Hope this will help.
