Bug 1674659

Patch posted at: https://github.com/gluster/gluster-ansible-features/pull/20

FQDN validation with dig failed, as there is check 'localhost' as hostname with dig command and this blocks the RHHI deployment

Error exactly goes like this:
<snip>
TASK [gluster.features/roles/gluster_hci : Check if valid FQDN is provided] ****
failed: [dhcp37-124.lab.eng.blr.redhat.com -> localhost] (item=localhost) => {"changed": true, "cmd": ["dig", "localhost", "+short"], "delta": "0:00:00.117666", "end": "2019-02-21 14:29:31.546174", "failed_when_result": true, "item": "localhost", "rc": 0, "start": "2019-02-21 14:29:31.428508", "stderr": "", "stderr_lines": [], "stdout": "", "stdout_lines": []}

sas, localhost will fail because it is not a valid FQDN. Can you provide the playbook that you used.
We should not have localhost in the playbook. This is the expected result.

The playbook has to fail if there an entry called localhost in the gluster_inventory.yml
Else you have to set: gluster_features_fqdn_check: false

Inventory file provided by sas had the lines:

local:
  hosts:
    localhost: null
  vars:
    ansible_ssh_common_args: '-o BatchMode=yes'

which caused the above error, and it is the expected behaviour to fail because localhost is not a valid FQDN.
To sidestep the error we should set the variable - gluster_features_fqdn_check: false

Yes, this is the inventory file generated by cockpit-ovirt-dashboard.
So its the bug in this construction of this inventory file.

I have reported a bug[1] on cockpit-ovirt-dashboard for the same
And this bug[1] blocks verification of this bug

[1] - https://bugzilla.redhat.com/show_bug.cgi?id=1679536

Verified with gluster-ansible-features-1.0.4-3 with the following tests

1. Using IPs for hostnames and the deployment failed
2. Use the non-resolvable hostnames and also the deployment fails
