Images intended for use with Kubernetes CAPI providers. More details on https://image-builder.sigs.k8s.io/capi/capi.html.
The images are built with the Image Builder, a collection of cross-provider Kubernetes virtual machine image building utilities.
When a Kubernetes series changes to EOL status, the corresponding builds are deactivated here and only the last version of this series will remain available as an image in the future.
The following images contain the latest stable releases,
which are updated as required. This means that the image for version 1.27
contains, for example, version 1.27.3.
| Series | Current Version | Image URL | End of Active Support | End of Maintenance Support |
|---|---|---|---|---|
| v1.34 | v1.34.3 | ubuntu-2404-kube-v1.34.qcow2 | 2026-12-28 | 2027-04-28 |
| v1.33 | v1.33.7 | ubuntu-2404-kube-v1.33.qcow2 | 2026-04-28 | 2026-06-28 |
| v1.32 | v1.32.10 | ubuntu-2204-kube-v1.32.qcow2 | 2025-12-28 | 2026-02-28 |
For each Kubernetes series, a last-X file is published to the object storage during the
CI build process. These files contain the build date and the path to the latest image
for that series.
The files are available at:
https://nbg1.your-objectstorage.com/osism/openstack-k8s-capi-images/last-1.32
https://nbg1.your-objectstorage.com/osism/openstack-k8s-capi-images/last-1.33
https://nbg1.your-objectstorage.com/osism/openstack-k8s-capi-images/last-1.34
Each file contains a single line in the format:
YYYY-MM-DD ubuntu-XXXX-kube-vX.XX/ubuntu-XXXX-kube-vX.XX.X.qcow2
For example, last-1.32 might contain:
2025-11-15 ubuntu-2204-kube-v1.32/ubuntu-2204-kube-v1.32.10.qcow2
This tells you that:
- The build was created on 2025-11-15
- The current version is v1.32.10
- The image uses Ubuntu 22.04
- The full download URL is:
https://nbg1.your-objectstorage.com/osism/openstack-k8s-capi-images/ubuntu-2204-kube-v1.32/ubuntu-2204-kube-v1.32.10.qcow2
To fetch the current version programmatically:
curl -s https://nbg1.your-objectstorage.com/osism/openstack-k8s-capi-images/last-1.32This section contains images for Kubernetes versions that have reached End of Life (EOL). These images are no longer updated but remain available for download. Only the final patch version of each EOL series is kept.
