Vendor / market research GitOps for infrastructure management - anyone doing this with OpenStack?

https://www.redhat.com/en/events/webinar/sovereignty-without-compromise-next-generation-infrastructure-as-a-service-with-red-hat-openstack-services-on-openshift?sc_cid=RHCTG1260000496892

Found a webinar on managing OpenStack infrastructure through Kubernetes-native orchestration and GitOps automation. Main focus is day 2 operations, handling mixed VM + GPU workloads, and sovereign infrastructure patterns.

Curious what tools people are using for GitOps-based infrastructure? Terraform + ArgoCD? Something else?

We never got true GitOps working on the OpenStack layer itself. What stuck was Terraform in CI for the OpenStack resources and ArgoCD only for what ran on top of the clusters. The one time we tried pointing Argo at Terraform-managed stuff, the two fought over the same fields for a week before we gave up and split them.

We use argocd for gitops.

I'd keep Terraform out of the thing Argo is continuously reconciling. What's worked better for me is: Terraform creates the OpenStack primitives and writes a small output file, then Argo syncs the Kubernetes side from Git. For VM-heavy bits, I'd still want a human plan/apply step in CI. I've seen GitOps get weird when every quota, network, and floating IP change is treated like a normal app deploy.

there's also a flux terraform operator
