Overcloud deployment fails with "InvalidConfigException: Address JSON objects require 'ip_netmask' to be configured"

Solution Verified - Updated -

Issue

  • Management network doesn't get ip_netmask from the allocation pool due to which the deployment fails. This can be noticed in /etc/os-net-config/config.json.

    [stack@undercloud-0 ~]$ cat /etc/os-net-config/config.json | python -m json.tool
    .
    .
       "addresses": [
                   {
                          "ip_netmask": ""
                   }
            ],
    .
    .
