Releases¶

Versioning¶

Releases follow Gardener. A tag like v1.155.1-0 is the first release for Gardener 1.155.1. The suffixes -1, -2 and so on are fixes to this repository for the same Gardener version.

A new release is published automatically for every new Gardener version. The release notes list the Gardener changes first, then the changes in this repository.

What is tested¶

Each release is tested with its Gardener version, and that means the Gardener installation only: management cluster, garden cluster, Gardener Operator, extensions and the managed seed. Shoots and everything else you run on top are outside the test scope.

Using a release¶

Pin a release with git checkout <tag>. Then run the playbook as described in Installation.

To run another Gardener version, set gardener_operator_version in your group_vars/all.yml. This works, but it is not tested.

Minimum Gardener version¶

The minimum Gardener version is 1.142.0. Since that version, nginx-ingress is no longer deployed and all Gardener endpoints are served through the Istio ingress gateway. Older versions are not supported.

Upgrading¶

How to upgrade Gardener, the provider extensions, the garden cluster and the management cluster step by step is described in Operations.
