[Starlingx-discuss] User questions
Hi StarlingX Community, I got the below questions about StarlingX, and need a little help with finding the answers: 1. Can a subcloud-group be rehomed (can see that a subcloud can, but what about a subcloud-group)? 2. Can a subcloud belong to multiple subcloud groups for administrative and monitoring/reporting purposes? - For example, having all subclouds in a given region with the same update/version policies, and at the same time having all instances running a particular application to have specific settings for that application regardless of region setting? 3. Is it possible to provision a specific application to an entire subcloud-group in a single action? 4. Last one - is it possible to run OpenStack in subclouds? Most of the documentation only seems to mention K8s. Thank you for your help in advance. Best Regards, Ildikó ——— Ildikó Váncsa Director of Community Open Infrastructure Foundation
Hi Ildiko, I might be able to help with the last question:
4. Is it possible to run OpenStack in subclouds? Most of the documentation only seems to mention K8s.
I am pretty sure this is not being tested recently, so we should definitely revisit it and re-test if the community finds it important. What I know from the past is that the stx-openstack application SHOULD BE supported on subclouds and SHOULD NOT BE supported on central (system controller) clouds. If we feel like revisiting this deployment, we can arrange it as part of stx.10 maybe? Hoping it helps you :) Thales ________________________________ From: Ildiko Vancsa <ildiko@openinfra.dev> Sent: Tuesday, August 8, 2023 7:15 PM To: StarlingX ML <starlingx-discuss@lists.starlingx.io> Subject: [Starlingx-discuss] User questions CAUTION: This email comes from a non Wind River email account!

[Ildiko] This reads a little confusing to me. What does it mean that stx-openstack should not be supported on central clouds? Does that mean that the central cloud is not expected to run workloads? As OpenStack is a cloud platform that powers large data centers, I can see how it might not be implemented to run in sub-clouds, but rather in the central data center. +1 for more targeted testing in this area.
If we feel like revisiting this deployment, we can arrange it as part of stx.10 maybe?
Do you mean the central cloud or the sub-cloud deployment?

Hi Ildiko, Unfortunately, I am not the best person to talk about a Distributed Cloud deployment, don't have much experience with such installation. I will add this to my list to directly ping Greg once he is back from his vacation and we can elaborate on this topic for you and for the community. How does it sound?

Hi Thales, No worries, thank you for looking into it and offering to give a heads up to Greg as well when he’s back from vacation. Are there others with experience with Distributed Cloud setup to chime in? Best Regards, Ildikó ——— Ildikó Váncsa Director of Community Open Infrastructure Foundation

Agree with Thales in that openstack testing in DC Environment has been limited lately. In previous releases of STX, openstack has been tested on DC Subclouds. openstack is NOT supported on the central cloud (SystemController) ... believe there really just hasn't been a requirement for this, so not tested or supported.

Hi StarlingX Community, I got the below questions about StarlingX, and need a little help with finding the answers: 1.

Can a subcloud belong to multiple subcloud groups for administrative and monitoring/reporting purposes? - For example, having all subclouds in a given region with the same update/version policies, and at the same time having all instances running a particular application to have specific settings for that application regardless of region setting?

There isn't a means to establish a relation between subcloud group and custom applications otherwise. 3.

One would need to write a small script for this custom provisioning. 4. Last one - is it possible to run OpenStack in subclouds? Most of the documentation only seems to mention K8s. [TN] As OpenStack can run in a StarlingX standalone system, it should run in a subcloud as well. However, there were some issues with OpenStack on StarlingX since the switch to Debian which only got resolved since June this year. There is no support of OpenStack in the system controller. The system controller was designed to monitor and manage the subclouds. It's not meant to run custom apps/workloads that are not for these purposes. Keep in mind that StarlingX subcloud can be a simplex or multi-node with many workers and storage. Thank you for your help in advance.
