Garden Linux is a Debian Linux derivative specifically designed for Gardener managed Kubernetes clusters. Garden Linux versions share their names with the upstream Debian versions. The most current Garden Linux version is bullseye (Debian 11 - Testing). Garden Linux leverages Debian’s security tracker and its large community of package maintainers.
Unlike Debian, Garden Linux is not a general purpose Linux! We have carefully selected every single package to include only those that are needed on a Gardener Kubernetes node. We follow the immutable infrastructure paradigm. Therefore parts of the filesystem are read only, resulting in immutable, more secure Linux servers. If you need more packages than those that are included in the Garden Linux images you cannot install them during runtime. All software that should run on the server has to be deployed via Kubernetes.
Garden Linux comes in different flavors, optimized for deployment in different environments.
Garden Linux build scripts and manifests are shared with the public via GitHub. You need a Debian machine to build the Garden Linux Debian distribution. Garden Linux images in different Flavors can be downloaded from this website.
