Comment 14 for bug 1880579

We set the ansible_ssh_user to "stack" but now we run to another known issue

TASK [Write octavia inventory] ***************************************************************************************************************************************************************
Thursday 04 June 2020 12:30:18 +0000 (0:00:00.512) 0:00:04.344 *********
fatal: [undercloud]: FAILED! =>
  msg: |-
    The task includes an option with an undefined variable. The error was: 'dict object' has no attribute 'ansible_hostname'

    The error appears to be in '/home/stack/config-download/overcloud/external_deploy_steps_tasks.yaml': line 381, column 5, but may
    be elsewhere in the file depending on the exact syntax problem.

    The offending line appears to be:

        name: Write group_vars file
