OpenStack Neutron on Kubernetes in Digital Ocean VPC

Question

I'm been trying to get OpenStack Neutron working properly on top of a Kubernetes cluster in Digital Ocean.

My Setup:

• OpenStack is installed using OpenStack-Helm and runs on top of a Kubernetes cluster.
• Each K8s node serves as both a compute and networking node for OpenStack.
• Neutron and Open vSwitch (OVS) are installed and running on every node.

The Kubernetes cluster itself runs inside a DigitalOcean VPC, and all pods inside it successfully use the VPC networking.

My Goal:

• I want to expose OpenStack VMs to the same DigitalOcean VPC that Kubernetes is using.

• Once OpenStack VMs have native connectivity in the VPC, I plan to set up DigitalOcean LoadBalancers to expose select VMs to the broader internet.

The Challenge:

Even though I have extensive OpenStack experience on bare metal, I’ve really struggled with this particular setup. Networking in this hybrid Kubernetes + OpenStack environment has been a major roadblock, even though:

• OpenStack services are running
• Compute is launching VMs
• Ceph storage is fully operational
