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.

Start up a DevStack environment with all Cluster API dependencies

./hack/stack.sh

Upload an image to use with Magnum and create cluster templates

pushd /tmp
source /opt/stack/openrc
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;
popd

Spin up a new cluster using the Cluster API driver

openstack coe cluster create \
  --cluster-template k8s-v1.25.12 \
  --master-count 3 \
  --node-count 2 \
  k8s-v1.25.12

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

eval $(openstack coe cluster config k8s-v1.25.12)
