Hi Frank:

As synced with Tingjie, this is my understanding for Rook manage the configuration instead of sysinv.

1, Remove ceph config and status query from sysinv
[BR] So this would be done in new reviews, current code posted is still coupled with sysinv ?
2, create another tool, like rook-client to launch and provision ceph cluster
[BR] Wouldn't this just be chart overrides ? Why is a tool required ?
3, one helm plugin like rbd-provision, which depends on newly created tool

BR!

Martin:

Thanks for posting your reviews and the update on the current status for this feature.

I was unable to attend the containerization meeting this week so wasn't able to have Tingjie or you give an update on the open actions for the feature.  From the Jan 14 minutes [1] one of the actions is to determine "how can you have Rook do all the configuration and not have sysinv involved"

For now I suggest you add an additional item to your Tasks to do list to identify a design that does not require sysinv for the configuration and instead has Rook manage the configuration.  I would like to ask that we discuss further at the next containerization meeting and if possible review a proposal from yourself and Austin for this item.

Subject: [Starlingx-discuss] ceph containerization patch review

Hi folks

I enabled containerized ceph cluster with simplex. You can begin to review my patch. I propose to build an image and deploy a simplex system with these patch to check.

https://review.opendev.org/#/c/681457/
https://review.opendev.org/#/c/687340/
https://review.opendev.org/#/c/706256/
https://review.opendev.org/#/c/699557/
https://review.opendev.org/#/c/699556/

And I know there is other story, like remove ceph as default backend storage, maybe some conflict, we can discuss together.


Tash Done:
1, disable native ceph cluster in ceph.pp
2, disable ceph daemon monitoring in service manager
3, add rook-ceph helm chart to launch ceph cluster
4, add override in stx-config to generate override with starlingx system config
5, sysinv add label in provision stage, to make containerized ceph mon and ceph mgr on designed host
6, add rook-ceph-provisioner helm chart to generate storage class, secret, config and pool for stx-application
7, enabled stx-openstack with containerized ceph
8, update ceph wrapper in stx-config to set or get containerized ceph cluster

All these tasks done is enabled with simplex only.

Task to do:
1,  enable add osd runtime, after system provisioned
2, fix know issue, if system reboot, ceph cluster launch fail
3, enable bluestore and filestore, currently there is only bluestore
4, enable multi-node and duplex
5, enable swift with containerized ceph
6, enable fm alarm for containerized ceph
7, check backup and restore for containerized ceph
8, check system upgrade or how to transit from native ceph cluster to containerized ceph cluster
9, code cleanup
10, update unit test in stx-config

BR!
