Description Gurenko Alex 2019-04-03 07:22:20 UTC

Description of problem: When trying to set public endpoints to serve over IPv6, stackrc creation fails due to missing logic for parsing IPv6 address for OS_AUTH_URL


Version-Release number of selected component (if applicable):
OSP13, puddle 2019-03-18.1


How reproducible: 100%


Steps to Reproduce:
1. Add undercloud_public_host = <IPv6 address>
2. run openstack undercloud install

Actual results:

Expected results:

Undercloud install complete

Additional info:
The issue is cause by link string OS_AUTH_URL=https://{{public_host}}:13000/ (for HTTPS) or OS_AUTH_URL=https://{{public_host}}:5000/ (for HTTP) in /usr/share/instack-undercloud/undercloud-install/os-apply-config/root/stackrc.

Manually modifying these url to include [] for IPv6 address fixes the issue.

Comment 4 Bob Fournier 2019-04-25 16:49:42 UTC

Looks like we need to add a public-host-wrapped env setting.  However note that IPv6 on the provisioning network isn't supported in OSP-13.  There are some fixes for it but its not planned until OSP-16 - https://bugzilla.redhat.com/show_bug.cgi?id=1459187.  Its likely that you'll encounter other problems once you got by this in OSP-13.

Note that OSP-16 doesn't use instack-undercloud so this fix probably isn't needed there.

Comment 5 Bob Fournier 2019-04-27 14:36:50 UTC

Alex - can this be retargeted to OSP-16 to match support for IPv6 on provisioning network - https://bugzilla.redhat.com/show_bug.cgi?id=1459187?

Comment 7 Bob Fournier 2019-04-28 14:34:08 UTC

Thanks Alex.  OK, its different if we don't need IPv6 provisioning network.  With this fix does it complete?  Agreed its an easy fix and we can get it in.

There are other pending BZs that prevents getting a smooth experience, but with all BZs worked around it does get deployed, yes.

Comment 16 Bob Fournier 2019-06-16 18:28:08 UTC

Hi Alex - if you are testing IPv6 with OSP-13 it would be great if you can also test one.  Thanks.

Comment 18 Gurenko Alex 2019-07-03 16:35:37 UTC

Verified on puddle 2019-06-28.1

[stack@undercloud-0 ~]$ rpm -q instack-undercloud
instack-undercloud-8.4.7-10.el7ost.noarch

stackrc file generated properly and works as expected.
