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 //cdn.thegeekdiary.com/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
