Hi Vladimir, This is something that I’ve been looking at lately, I’ve recently started to build the following service operator for OpenStack: https://github.com/vexxhost/openstack-service-operator It supports endpoints and services right now, I want to try and see what it looks like to replace the keystone jobs by this and do users next. There’s also other things like for example the image uploads being managed as Kubernetes jobs. I’d love it to be in a world where a db-sync is the only job we have. The goal of the service operator is to be a bit more generic, I’m thinking even the Cluster API could take advantage of something like this similar to how Azure takes advantage of their Azure Service Operator for machines.

Learn why this is important<https://aka.ms/LearnAboutSenderIdentification> Hi Mohammed, Thanks a lot for reporting the bug. IMO at this point it is much easier to fix the db-init script and make it compatible with SQLAlchemy 2.0. I'll take care of this. It is interesting that a couple days ago there was a small discussion in the #openstack-helm Slack chat about utilizing CRs when bootstrapping the deployments (specifically we discussed creating Keystone users). My first impression about this was that it is kinda a layer violation when you try to create such entities not directly but via K8s API. But it looks like there are cases when having this kind of simple operator for managing databases/users/keyrings could bring convenience. One of our users mentioned the Keystone federation case when some customization is necessary and using CRs is much easier than modifying the Keystone init script in the helm-tooking chart. We also had a similar case when we switched to Rook managed Ceph clusters by default. We introduced the ceph-adapter-rook chart that creates Ceph keyrings/configs, but probably the operator would be more convenient here. So, taking into account that this is not the first time this topic (OSH operator) has come up recently we could try to go this way. Let's maybe implement a POC for the start and then gather opinions.
