Changing Docker IP Ranges on the Operations Manager

Operations Manager devices includes Docker.

By default Docker and NetOps utilize the 172.17.0.0/16 subnet. This has the potential to cause collisions inside some networks.

To avoid subnet collision, follow the instructions below.

Login to the Operations Manager shell CLI as root. If you are already logged in as admin user become root with "sudo -i". Use vi to edit /etc/docker/daemon.json and change 172.17.0.1/16 to 10.1.0.1/24 or your preferred IP address. This is the line you need to change.

"bip": "172.16.0.1/16"

Once that’s done, restart docker networking.

systemctl restart docker

If you are not familiar with vi editor, run the following commands which achieves the same results.

sed -i 's/172.17.0.1\/16/10.1.0.1\/24/' /etc/docker/daemon.json

systemctl restart docker
