Gardener

Deliver fully-managed clusters at scale everywhere with your own Gardener installation

A Managed Kubernetes Service Done Right

Cloud-Native at Heart

As a standard Kubernetes extension, Gardener adheres to the same principles for resiliency, manageability, observability and high automation by design.

Open Community Effort

The Gardener project is committed to fostering an open community of collaborators and adopters. We aim to deliver a standard solution that meets the needs of our entire community and ecosystem.

Solving Authentic Problems

Gardener was born as a solution for actual and common problems such as controlling the Kubernetes stack, minimizing TCO, and operating in restricted environments, at massive scale.

Kubeception

By running Kubernetes on Kubernetes, Gardener provides high availability and resource usage efficiency

Cluster Fleet Hub

A single seed cluster can scale to register and manage thousands of shoot clusters as long as a gardenlet is deployed, regardless of their location.

Kubernetes Native

Gardener manages clusters very much like pods are orchestrated in Kubernetes. Cluster workloads are scheduled and Gardenlets, similar to Kubelets, take over to manage them in particular environments in a loosely coupled, controller pattern.

Fully Managed

Gardenlets manage control planes, worker nodes (full lifecycle, self-healing and updates) and cluster components, such as the overlay network, DNS and certificates, control plane monitoring and logging stack, to provide automation, resilience and observability.

Scalable by Design

A single Kubernetes cluster can host an enormous amount of control planes. Gardener can scale-out massively by more control plane clusters and letting the Gardenlets do the heavy lifting. In fact, those clusters can also be managed by Gardener for maximum efficiency.

Get The Kubernetes You Really Want

Gardener provisions flexible clusters without the need to set them up yourself

Configurable

Gardener control planes allow you to control a wide range of features gates and configurations.

The updates you want, when you want them

No more unexpected updates! Gardener allows you to update Kubernetes to the version you want, when you want it, rather than when your cloud provider decides. It even allows you to update your Host OS when desired.

100% Kubernetes compliant

Gardener is Kubernetes native and is not shy to be completely transparent on its compliance, proudly holding the 100% badge with public evidence for that.

The one you already know

Gardener delivers the same Kubernetes you know from kubernetes.io and are certified for. The same binaries, the same tools; you are already trained to use it.

However You Want It

Extend And Contribute To Gardener

Extensible By Design

Gardener is a modular system of managed extensions around a robust core, fully adaptable in multiple dimensions. Extend the existing extension set or add completely new pieces. And while you are at it, why not contribute them back to the community and benefit from the contributions of others?

Managed Extensions

Gardener watches over and manages extensions, automatically reconciling their actual and desired state as designed.

Control the Stack

You are in control of the setup for the cluster that will be delivered by Gardener. Choose the components you actually need.
