Description of problem:

The code in tripleo-ipa assumes that all of these entries contain a domain and that forward and reverse dns entries should be added. This is true until the user specifies something unrelated in ExtraHostFileEntries.


Version-Release number of selected component (if applicable):

OSP 16.1

How reproducible:

This was reproduced in infrared

Steps to Reproduce:

The issue occured in infrared with the following configuration: 

  ExtraHostFileEntries:
  - '1.2.3.4 stillhavemythumb'

Actual results:

The deployment fails with:

TASK [tripleo_ipa_dns : set forward dns record values] *************************
Thursday 23 July 2020  15:13:02 +0000 (0:00:00.693)       0:22:05.757 *********
fatal: [undercloud]: FAILED! => {"msg": "The task includes an option with an undefined variable. The error was: list object has no element 1\n\nThe error appears to be in '/usr/share/ansible/roles/tripleo_ipa_dns/tasks/dns.yaml': line 18, column 3, but may\nbe elsewhere in the file depending on the exact syntax problem.\n\nThe offending line appears to be:\n\n\n- name: set forward dns record values\n  ^ here\n"}

Expected results:

DNS entries are added, deployment succeeds.

Additional info:

A lachupad bug was reported to gather feedback. The proposal is to only add hosts with cloud domains, all other hosts will be ignored, which will resolve the issue.
