Feature Description
By default, Docker uses the subnet range, 172.17.0.0/16 for container networking. If the same subnet range or an IP address from the range is already being used by some other resource in the same cluster environment, it might lead to a conflict.
This feature enables the user to configure and override the default value for the Docker subnet used by the SMI Cluster Manager (CM) or Inception VM. For the CM, this configuration is set by using the CM Ops-Center, whereas the Inception VM uses the deploy.yaml file to achieve the same configuration.
The deploy.yaml is enhanced to contain additional parameter, configuration with a sub-parameter, docker-address-pools. This YAML file contains a base for the CIDR range to use and a size for the size of the subnet to reserve for the new network.
