# Kubernetes controller-runtime Project

The Kubernetes controller-runtime Project is a set of go libraries for building

Controllers. It is leveraged by [Kubebuilder](https://book.kubebuilder.io/) and

[Operator SDK](https://github.com/operator-framework/operator-sdk). Both are

a great place to start for new projects. See

[Kubebuilder's Quick Start](https://book.kubebuilder.io/quick-start.html) to

see how it can be used.

Documentation:

- [Package overview](https://pkg.go.dev/sigs.k8s.io/controller-runtime/pkg)

- [Basic controller using builder](https://pkg.go.dev/sigs.k8s.io/controller-runtime/pkg/builder#example-Builder)

- [Creating a manager](https://pkg.go.dev/sigs.k8s.io/controller-runtime/pkg/manager#example-New)

- [Creating a controller](https://pkg.go.dev/sigs.k8s.io/controller-runtime/pkg/controller#example-New)

# Versioning, Maintenance, and Compatibility

The full documentation can be found at [VERSIONING.md](VERSIONING.md), but TL;DR:

Users:

- We follow [Semantic Versioning (semver)](https://semver.org)

- Use releases with your dependency management to ensure that you get compatible code

- The main branch contains all the latest code, some of which may break compatibility (so "normal" `go get` is not recommended)

Contributors:

- All code PR must be labeled with :bug: (patch fixes), :sparkles: (backwards-compatible features), or :warning: (breaking changes)

- Breaking changes will find their way into the next major release, other changes will go into an semi-immediate patch or minor release

- For a quick PR template suggesting the right information, use one of these PR templates:

  * [Breaking Changes/Features](/.github/PULL_REQUEST_TEMPLATE/breaking_change.md)

  * [Backwards-Compatible Features](/.github/PULL_REQUEST_TEMPLATE/compat_feature.md)

  * [Bug fixes](/.github/PULL_REQUEST_TEMPLATE/bug_fix.md)

  * [Documentation Changes](/.github/PULL_REQUEST_TEMPLATE/docs.md)

  * [Test/Build/Other Changes](/.github/PULL_REQUEST_TEMPLATE/other.md)

## Compatibility

Every minor version of controller-runtime has been tested with a specific minor version of client-go. A controller-runtime minor version *may* be compatible with

other client-go minor versions, but this is by chance and neither supported nor tested. In general, we create one minor version of controller-runtime

for each minor version of client-go and other k8s.io/* dependencies.

The minimum Go version of controller-runtime is the highest minimum Go version of our Go dependencies. Usually, this will

be identical to the minimum Go version of the corresponding k8s.io/* dependencies.

Compatible k8s.io/*, client-go and minimum Go versions can be looked up in our [go.mod](go.mod) file.

|          | k8s.io/*, client-go | minimum Go version |
