Description Attila Darazs 2016-02-04 12:52:40 UTC 
Description of problem:
We recently debugged a bug that was the result of non-working DNS resolution and made RabbitMQ fail during deployment without helpful errors, as the socket bindings got really slow without working DNS.

This highlighted the need for a DNS check during the network validation, maybe with a configurable host to resolve that will work even in environments where the resolution is limited to local names.

This idea came out of bug #1304423
Comment 2 Mike Burns 2016-04-07 21:07:13 UTC 
This bug did not make the OSP 8.0 release.  It is being deferred to OSP 10.
Comment 4 Jaromir Coufal 2016-09-30 07:36:59 UTC 
-> Validations
Comment 5 Ola Pavlenko 2016-11-23 15:41:04 UTC 
Could you please update the status of this RFE?
Comment 6 Tomas Sedovic 2016-11-24 11:31:49 UTC 
No update. We didn't have time to work on this (so it won't be in OSP 10).
Comment 7 Ola Pavlenko 2016-12-12 14:38:17 UTC 
Potential candidate for M-3
Comment 16 Udi Kalifon 2018-04-09 12:23:39 UTC 
Verified in: openstack-tripleo-validations-8.4.0-1.el7ost.noarch

This was implemented as a pre-deployment validation only, and will run on the undercloud. The user cannot run this on the overcloud during the deployment, before the services are configured, so deployments may still fail if DNS is misconfigured on the overcloud.

Atilla - consider opening a new bug to do a similar test during the deployment, and stop the deployment with a clear error message if DNS is not working. Or re-open this bug if you feel it's not properly completed.
Comment 17 Attila Darazs 2018-04-25 13:05:41 UTC 
Should be fine, clearing needinfo.
