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.
Example extension resource:
apiVersion: extensions.gardener.cloud/v1alpha1
kind: Extension
metadata:
name: "extension-dns-service"
namespace: shoot--project--abc
spec:
type: shoot-dns-serviceYou can run the controller locally on your machine by executing make start. Please make sure to have the kubeconfig to the cluster you want to connect to ready in the ./dev/kubeconfig file.
Static code checks and tests can be executed by running make verify. We are using Go modules for Golang package dependency management and Ginkgo/Gomega for testing.
Feedback and contributions are always welcome. Please report bugs or suggestions as GitHub issues or join our Slack channel #gardener (please invite yourself to the Kubernetes workspace here).
