11/15/2025, 2:06 PMOptions I’m considering:
1. Use embedded RKE2 cloud provider and install on top of it
2. Use OpenStack Cloud Provider + Harvester CSI + KubeVIP
3. Use Harvester Cloud Provider + KubeVIP + Octavia (which may end up in having two cloud providers with possible lconflicts)
Is running two cloud providers on one RKE2 cluster even supported?

11/15/2025, 7:43 PMYou should use the cloud provider for whatever hosts the nodes. Cloud provider is specifically for talking to whatever is hosting the nodes to discover node addresses, hardware type, and other metadata.

11/15/2025, 9:56 PMThank you @creamy-pencil-82913! That means Harvester Cloud Provider, then I'll install OpenStack LBaaS on top of that.
Octavia is a must, because I need public load balancers and it's not a trivial task to implement properly. Harvester which has its own LB allows you to configure it only on management network.

11/15/2025, 10:19 PMIt looks like to install OctaviaLB, you need to have full CPI with only LB section configured:

I've did a POC some time ago and it was working correctly, question how risky is it?

11/18/2025, 12:11 AMIf you only need octavia support, you could try the Openstack Cloud Controller Manager https://github.com/kubernetes/cloud-provider-openstack
