Gardener Extension for Azure provider
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.
This controller implements Gardener's extension contract for the Azure provider.
An example for a ControllerRegistration resource that can be used to register this controller to Gardener can be found here.
Please find more information regarding the extensibility concepts and a detailed proposal here.
Supported Kubernetes versions
This extension controller supports the following Kubernetes versions:
| Version | Support | Conformance test results |
|---|---|---|
| Kubernetes 1.27 | 1.27.0+ | N/A |
| Kubernetes 1.26 | 1.26.0+ | |
| Kubernetes 1.25 | 1.25.0+ | |
| Kubernetes 1.24 | 1.24.0+ | |
| Kubernetes 1.23 | 1.23.0+ | |
| Kubernetes 1.22 | 1.22.0+ |
Please take a look here to see which versions are supported by Gardener in general.
How to start using or developing this extension controller locally
You can run the controller locally on your machine by executing make start.
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 Support
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).
