How to change the default IP address of docker bridge

Question: what is the proper procedure to reconfigure the docker interface to use an address range (e.g., > 172.200) for the virtual interfaces it uses?

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:

# vi /etc/docker/daemon.json
{
  "bip": "172.200.0.1/16"
}

Then restart the docker daemon as root.

On CentOS/RHEL 6 use the service command to restart the docker service:

# service docker restart

On CentOS/RHEL 7, use the systemctl command to restart the docker service.

# systemctl restart docker
