Deliver fully-managed clusters at scale everywhere with your own Kubernetes-as-a-Service
  • Upcoming Community Call - Cilium / Isovalent Presentation October 6, 2022


    This community call will be led by Raymond de Jong.


    This meeting will explore the uses of Cilium, an open source software used to secure the network connectivity between application services deployed using Kubernetes, and Hubble, the networking and security observability platform built on top of it.

    Viewers will be shown how to check for connectivity and how to carry out basic troubleshooting. Later on in the meeting, an overview will be given of the network policy and the procedure for switching from Calico will be demonstrated.

    Q&A is planned after the main part to look at any issues you might have encountered. Come join us!

    You can join this meeting on Zoom (Meeting ID: 996 5655 0236, Passcode: 165357).

  • Community Call - Gardener Extension Development June 17, 2022


    This community call was led by Jens Schneider and Lothar Gesslein.


    Starting the development of a new Gardener extension can be challenging, when you are not an expert in the Gardener ecosystem yet. Therefore, the first half of this community call led by Jens Schneider aims to provide a “getting started tutorial” at a beginner level. 23Technologies have developed a minimal working example for Gardener extensions, gardener-extension-mwe, hosted in a Github repository. Jens is following the Getting started with Gardener extension development tutorial, which

    In the second part of the community call, Lothar Gesslein introduces the gardener-extension-shoot-flux, which allows for the automated installation of arbitrary Kubernetes resources into shoot clusters. As this extension relies on Flux, an overview of Flux’s capabilities is also provided.

    If you are left with any questions regarding the content, you might find the answers at the Q&A session and discussion held at the end.

  • Community Call - Deploying and Developing Gardener Locally March 25, 2022


    This community call was led by Tim Ebert and Rafael Franzke.


    So far, deploying Gardener locally was not possible end-to-end. While you certainly could run the Gardener components in a minikube or kind cluster, creating shoot clusters always required to register seeds backed by cloud provider infrastructure like AWS, Azure, etc..

    Consequently, developing Gardener locally was similarly complicated, and the entry barrier for new contributors was way too high.

    In a previous community call (Hackathon “Hack The Metal”), we already presented a new approach for overcoming these hurdles and complexities.

    Now we would like to present the Local Provider Extension for Gardener and show how it can be used to deploy Gardener locally, allowing you to quickly get your feet wet with the project.

    In this session, Tim Ebert goes through the process of setting up a local Gardener cluster. After his demonstration, Rafael Franzke showcases a different approach to building your clusters locally, which, while more complicated, offers a much faster build time.

Make It All About Kubernetes Again

Gardener abstracts environment specifics to deliver the same homogeneous Kubernetes-native DevOps experience everywhere
Cluster Fleet Hub
A single Gardener can scale to register and manage thousands of clusters, regardless of their location - public/private clouds, DC bare metal, regulated environments... anywhere a Gardenlet is deployed.
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 efficency.

Get The Kubernetes You Really Want

The clusters Gardener provisions are as flexible as DIY clusters, except you don’t have to do them yourself

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 and are certified for. The same binaries, the same tools; you are already trained to use it.

Everywhere You Want It

The compute resources you need, wherever you want them.
  • Alibaba Cloud
  • Amazon Web Services
  • Microsoft Azure
  • Google Cloud Platform
  • Metal-Stack
  • OpenStack
  • Equinix Metal
  • VMware vSphere

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 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.
