Project Gardener implements the automated management and operation of Kubernetes clusters as a service. Its main principle is to leverage Kubernetes concepts for all of its tasks. Recently, most of the vendor specific logic has been developed in-tree. However, the project has grown to a size where it is very hard to extend, maintain, and test. With GEP-1 we have proposed how the architecture can be changed in a way to support external controllers that contain their very own vendor specifics. This way, we can keep Gardener core clean and independent. An example for a ControllerRegistration resource that can be used to register this controller to Gardener can be found here.

Gardener implements the automated management and operation of Kubernetes clusters as a service and provides a fully validated extensibility framework that can be adjusted to any programmatic cloud or infrastructure provider. That means, Gardener gives you homogeneous clusters with exactly the same bill of material, configuration and behavior on all supported infrastructures, which you can see further down below in the section on our K8s Conformance Test Coverage. This made it possible to integrate managed services like GKE or Gardener. We would be more than happy, if the community would be interested, to contribute a Gardener control plane provider. Gardener's main principle is to leverage Kubernetes concepts for all of its tasks. In essence, Gardener is an extension API server that comes along with a bundle of custom controllers. It introduces new API objects in an existing Kubernetes cluster which is called garden cluster in order to use them for the management of end-user Kubernetes clusters which are called shoot clusters. These shoot clusters are described via declarative cluster specifications which are observed by the controllers. They will bring up the clusters, reconcile their state, perform automated updates and make sure they are always up and running. To accomplish these tasks reliably and to offer a high quality of service, Gardener controls the main components of a Kubernetes cluster etcd, API server, controller manager, scheduler. These so-called control plane components are hosted in Kubernetes clusters themselves which are called seed clusters. This is the main difference compared to many other OSS cluster provisioning tools: The shoot clusters do not have dedicated master VMs. Instead, the control plane is deployed as a native Kubernetes workload into the seeds the architecture is commonly referred to as kubeception or inception design. This does not only effectively reduce the total cost of ownership but also allows easier implementations for "day-2 operations" like cluster updates or robustness by relying on all the mature Kubernetes features and capabilities. Gardener reuses the identical Kubernetes design to span a scalable multi-cloud and multi-cluster landscape.

This controller operates on the OperatingSystemConfig resource in the extensions. Garden Linux OS configuration. Please find a concrete example in the example folder. MemoryOne on Garden Linux configuration spec. After reconciliation the resulting data will be stored in a secret within the same namespace as the config itself might contain confidential data.

Simply deploying over an existing landscape won't work with this release. The best idea is probably to remove the old cert-manager first before deploying the new one:. Note that this is will create new certificates for the dashboard ingress.
