Bug 1596321

Description of problem:

When running the ansible playbook to setup the registry the following error
is encountered.

TASK [openshift_hosted : set openshift_hosted facts] ****************************************************************************************************************
fatal: [l12886.example.com]: FAILED! => {}

MSG:

The task includes an option with an undefined variable. The error was: 'dict object' has no attribute 'openshift'

The error appears to have been in '/home/user/tst/openshift-ansible/roles/openshift_hosted/tasks/registry.yml': line 39, column 3, but may
be elsewhere in the file depending on the exact syntax problem.

The offending line appears to be:


- name: set openshift_hosted facts
  ^ here

exception type: <class 'ansible.errors.AnsibleUndefinedVariable'>
exception: 'dict object' has no attribute 'openshift'

        to retry, use: --limit @/home/user/.ansible-retry/deploy_registry.retry

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

CNS 3.10 pre release

How reproducible:

Steps to Reproduce:
1. Attempt to deploy registry with CNS configured for arbiter support
2.
3.

Actual results:

as above

Expected results:

installation succeeds

Additional info:

Workarounds were applied to get the installation to succeed.
1. Add glusterfs_ip to each of the nodes in the inventory
2. Take out the default `hostvars[node].openshift.common.ip`

This allows the installation to succeed.
