:rotating_light: Significant Changes :rotating_light:

Envtest Refactor & Support for 1.20+ Clusters (#1486)

This adds support for newer Kubernetes clusters, particularly those that require the use of authentication & the secure port, as well as some refactors & deprecation.

By and large, these changes should be transparent for most users.

As a result of the removal of the insecure port in newer k8s versions, authentication & authorization are now on by default in envtest (and the secure port is used by default). The built-in REST config now returns an admin account, meaning perceived impact should be minimal in most cases -- if you're using the built-in Environment.Config, things should just work.

However, if you manually construct new REST configs from raw URLs, things will break. You'll need to migrate to using Environment.AddUser instead.

Additionally, a number of options on ControlPlane & APIServer around the secure & insecure ports are deprecated -- see the docs for more details.

Envtest Setup Tool (#1488)

A new tool has been introduced for setting up envtest binaries at sigs.k8s.io/controller-runtime/tools/setup-envtest. This replaces the existing hack/setup-envtest.sh script, so if you were depending on that, you should switch. See the docs for more information.

Kubernetes Dependencies

Now at v1.21.1.

:warning: Breaking Changes

• Update Kubernetes v1.21 dependencies and use Go 1.16 (#1389) moderate impact: if you're on an old Go version, it's time to upgrade :wink:
• Envtest should modify CRDs appropriately when using webhooks (#1525) minimal impact: one of the methods on WebhookInstallOptions had a signature change. Mostly internal, expected that this method is unlikely to be called directly.
• Allow setting NewClientFunc w/o implementing an interface (#1473) moderate impact: If you're constructing a custom client, this'll change how you do so, but should make it easier in the long run.
• Support global controller options in component config (#1371) minimal impact: adds new method to Manager interface, generally only implemented by CR)
• Fix race in the delegating logger (#1361) minimal impact: exposed piece of internals was changed)
• Fakeclient: Handle Finalizers (#869) moderate impact: Finalizers in the fakeclient now behave similiar to the kube api, i.E. an object with a finalizer will not actually be deleted upon Delete and Updating an object with a DeletionTimestamp to remove the finalizer will result in deletion

:sparkles: New Features

• Structured args in Testing (#1541) -- the use of templated args (Environment.KubeAPIServerFlags) is now deprecated -- use GetAPIServer().Configure() instead.
• Clean up pkg/internal/testing (#1540)
• Cleanup Webhook server setup (#1504)
• EnvTest Binaries Setup Tool (#1488)
• Add SelectorsByObject option to cache (#1435)
• Simple helper for unmanaged webhook server (#1429)
• pkg/log/zap: clarify zap level vs. logr verbosity (#1485)
• Add ClientWithWatch for use in CLIs (#1460)
• Add client.StrategicMergeFrom (#1406)
