Hi Ankush:

Yes . Stx has ansible variant  cluster_pod_subnet to config the subnet of k8s cluster .

please check [1] for it.

Subject: [Starlingx-discuss] How to change docker default subnet?

Is there any Ansible configuration or CLI to redefine the docker subnet ? 

This default subnet 172.17. 0.0/16 is clashing with LAB network and I am not able to access the StarlingX cluster from LAB network.

Is it feasible to use "bip" option in "/etc/docker/daemon.json" ?

Thanks,
Ankush
