Integration with existent Magnum installation

[edesalve]

Hi all. I have installed all openstack services manually (RHEL 9.4, 2025.1 Epoxy, relevant docs). In the docs:

The heat driver described here is deprecated in favor of the k8s_capi_helm or k8s_cluster_api driver and will be removed in a future Magnum version.

So I imagine that k8s_cluster_api driver should be supported. Unfortunately following the getting started guide:

export OS_DISTRO=ubuntu # you can change this to "flatcar" if you want to use Flatcar
for version in v1.24.16 v1.25.12 v1.26.7 v1.27.4; do \
  [[ "${OS_DISTRO}" == "ubuntu" ]] && IMAGE_NAME="ubuntu-2204-kube-${version}" || IMAGE_NAME="flatcar-kube-${version}"; \
  curl -LO https://object-storage.public.mtl1.vexxhost.net/swift/v1/a91f106f55e64246babde7402c21b87a/magnum-capi/${IMAGE_NAME}.qcow2; \
  openstack image create ${IMAGE_NAME} --disk-format=qcow2 --container-format=bare --property os_distro=${OS_DISTRO} --file=${IMAGE_NAME}.qcow2; \
  openstack coe cluster template create \
      --image $(openstack image show ${IMAGE_NAME} -c id -f value) \
      --external-network public \
      --dns-nameserver 8.8.8.8 \
      --master-lb-enabled \
      --master-flavor m1.medium \
      --flavor m1.medium \
      --network-driver calico \
      --docker-storage-driver overlay2 \
      --coe kubernetes \
      --label kube_tag=${version} \
      k8s-${version};
done;

I get:

Cluster type (vm, ubuntu, kubernetes) not supported (HTTP 400)

It seems drivers are not present:

ls /usr/lib/python3*/site-packages/magnum/drivers
common  heat  __init__.py  k8s_fedora_coreos_v1  __pycache__

Is there a way to integrate magnum-cluster-api with my current deployment? What am I missing?

Thank you!

How did you deploy your OpenStack cloud?

[edesalve]

I have a manually installed OpenStack deployment on RHEL 9.4 (Epoxy 2025.1). I deployed the following services: Keystone, Glance, Nova, Neutron, Cinder, Heat, Barbican, Octavia and Magnum. It’s an all-in-one setup for testing. I followed the official documentation.

Magnum and Heat APIs are reachable, I can deploy VM workloads and was able to launch a basic Kubernetes cluster via Magnum CLI.

I need to run some VM with GPU support so it would be very ergonomic to have ubuntu as os instead of fcos.

You'll need to pip install the magnum-cluster-api package in this case to enable the functionality.

[edesalve]

Yes, magnum-cluster-api is indeed installed.
