Comment 2 for bug 1950171

containers-multinode job have correct HostnameMap in sync with DeployedServerPortMap:-

parameter_defaults:
  HostnameMap:
    overcloud-controller-0: node-0001753128

  DeployedServerPortMap:

In 1ctlr.yml[1] we are generating HostnameMap in an automated way:-

https://opendev.org/openstack/tripleo-quickstart/src/branch/master/config/nodes/1ctlr.yml#L6

~~~
    hostnamemap_override: "{{ hostvars[groups['overcloud'][0]].ansible_hostname }}"
~~~

1ctlr_1comp.yml have harcoded value, which seems to be the issue-

https://opendev.org/openstack/tripleo-quickstart/src/branch/master/config/nodes/1ctlr_1comp.yml#L7

~~~
    hostnamemap_override: overcloud-controller-foo-0
