[Starlingx-discuss] Stx-Openstack Install

[Andrew Bays]

Greetings,

I hope you all are well.  I have two virtualized Starling-X distributed
cloud deployments (both which consist of 2 VMs for AIO HA central cloud and
2 VMs for AIO HA subcloud).  One is version 3.0 and the other is 4.0.  Both
were created/installed following the official documentation:

-
https://docs.starlingx.io/deploy_install_guides/r3_release/distributed_cloud/index.html
-
https://docs.starlingx.io/deploy_install_guides/r3_release/openstack/install.html
-
https://docs.starlingx.io/deploy_install_guides/r4_release/distributed_cloud/index.html
-
https://docs.starlingx.io/deploy_install_guides/r4_release/openstack/install.html

My 3.0 deployment has both k8s and Openstack running on the central and
subcloud clouds.  I didn't have any luck with stx-openstack version 1.0-9
"latest" stable at first, so I tried "versioned"
<http://mirror.starlingx.cengn.ca/mirror/starlingx/release/3.0.0/centos/outputs/helm-charts/stx-openstack-1.0-19-centos-stable-versioned.tgz>,
which ended up working for me.  However, once I set my subcloud to
"managed" in the central cloud with dcmanager, I never saw the Openstack
identity sync status reach "in-sync", even after waiting a long time:

[sysadmin at controller-0 ~(keystone_admin)]$ dcmanager subcloud show subcloud2

Could anyone provide guidance on where to look in terms of pods, services,
logs, etc, such that I might find a clue as to what the problem might be?
Am I possibly missing configuration or some other required step to enable
the sync (beyond just setting the subcloud to "managed")?

For my 4.0 distributed cloud, I can't even get stx-openstack 1-0.49 (
"latest"
<http://mirror.starlingx.cengn.ca/mirror/starlingx/release/4.0.1/centos/flock/outputs/helm-charts/stx-openstack-1.0-49-centos-stable-latest.tgz>
or "versioned"
<http://mirror.starlingx.cengn.ca/mirror/starlingx/release/4.0.1/centos/flock/outputs/helm-charts/stx-openstack-1.0-49-centos-stable-versioned.tgz>)
to install.  The keystone-api-proxy pod fails with the following error in
its logs:

Has anyone else encountered this issue or know how to fix/work-around it?
It seems like some dependency is missing from the container image, but I'm
not sure.

Any insights/feedback on these two issues would be greatly appreciated.
Thank you!

Regards,
Andrew
