Auto build ubuntu kubernetes images for Openstack Magnum Service with a docker.
Ubuntu 24.04 + k8s 1.30+ as base image, tested with Magnum Capi driver.
- https://github.com/vexxhost/magnum-cluster-api - new Magnum driver supporting ClusterApi.
- https://github.com/vexxhost/capo-image-elements - project to build Kubernetes images.
- Fixed build error where systemctl enable containerd/kubelet would throw exception - service does not exist. Fixed by adding element-deps.
- Make sure the /etc/kubernetes/manifests directory exists for static pods (reduce logs on worker nodes).
- Added initialization of KUBECONFIG environment variable.
- cloud-init uses default Openstack datasources (Openstack, ConfigDrive)
- qemu-ga - added qemu guest agent to image.
- allow-root - allow root user and ssh root access with a key to kubernetes nodes.
- block-device-efi - make sure image works under Legacy and Uefi Bios (secure boot is not supported).
- prepull-images - pre pull openstack/cni container images.
