Cluster API driver for Magnum

Images

The images are built and published to an object storage bucket hosted at the VEXXHOST public cloud. These images are built and published for the latest stable release of Kubernetes.

Pre-built images

You can find the pre-built images for the latest stable release of Kubernetes at the following URL:

Building images

The Cluster API driver for Magnum provides a tool in order to build images, you can use it by installing the magnum-cluster-api package and running the the following command:

magnum-cluster-api-image-builder

Testing & Development

In order to be able to test and develop the magnum-cluster-api project, you will need to have an existing Magnum deployment. You can use the following steps to be able to test and develop the project.

  1. Start up a DevStack environment with all Cluster API dependencies

    ./hack/stack.sh

  2. Upload an image to use with Magnum and create cluster templates

    pushd /tmp
source /opt/stack/openrc
for version in v1.23.13 v1.24.7 v1.25.3; do \
   curl -LO https://object-storage.public.mtl1.vexxhost.net/swift/v1/a91f106f55e64246babde7402c21b87a/magnum-capi/ubuntu-2004-${version}.qcow2; \
   openstack image create ubuntu-2004-${version} --disk-format=qcow2 --container-format=bare --property os_distro=ubuntu-focal --file=ubuntu-2004-${version}.qcow2; \
   openstack coe cluster template create \
      --image $(openstack image show ubuntu-2004-${version} -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;
popd /tmp

  3. Spin up a new cluster using the Cluster API driver

    openstack coe cluster create \
  --cluster-template k8s-v1.25.3 \
  --master-count 3 \
  --node-count 2 \
  k8s-v1.25.3

  4. Once the cluster reaches CREATE_COMPLETE state, you can interact with it:

    eval $(openstack coe cluster config k8s-cluster)
