New core.gardener.cloud/v1alpha1 APIs required to extract cloud-specific/OS-specific knowledge out of Gardener core

Table of Contents

Summary

In GEP-1 we have proposed how to (re-)design Gardener to allow providers maintaining their provider-specific knowledge out of the core tree. Meanwhile, we have progressed a lot and are about to remove the CloudBotanist interface entirely. The only missing aspect that will allow providers to really maintain their code out of the core is to design new APIs.

This proposal describes how the new Shoot, Seed etc. APIs will be re-designed to cope with the changes made with extensibility. We already have the new core.gardener.cloud/v1alpha1 API group that will be the new default soon.

Motivation

We want to allow providers to individually maintain their specific knowledge without the necessity to touch the Gardener core code. In order to achieve the same, we have to provide proper APIs.

Goals

  • Provide proper APIs to allow providers maintaining their code outside of the core codebase.
  • Do not complicate the APIs for end-users such that they can easily create, delete, and maintain shoot clusters.

Non-Goals

  • Let's try to not split everything up into too many different resources. Instead, let's try to keep all relevant information in the same resources when possible/appropriate.

Proposal

In GEP-1 we already have proposed a first version for new CloudProfile and Shoot resources. In order to deprecate the existing/old garden.sapcloud.io/v1beta1 API group (and remove it, eventually) we should move all existing resources to the new core.gardener.cloud/v1alpha1 API group.

# This is useful for environments that are of the same type (like openstack) but may have different "instances"/landscapes.

Project resource

Special note: The members and viewers field of the garden.sapcloud.io/v1beta1.Project resource will be merged together into one members field. Every member will have a role that is either admin or viewer. This will allow us to add new roles without changing the API.

  #
  # If you use your own domain (not the default domain of your landscape) then you have to add additional keys to this secret.
  # The reason is that the DNS management is not part of the Gardener core code base but externalized, hence, it might use other
  # key names than Gardener itself.
  # The actual values here depend on the DNS extension that is installed to your landscape.
  # For example, check out https://github.com/gardener/external-dns-management and find a lot of example secret manifests here:
