Kubernetes controller-tools Project

The Kubernetes controller-tools Project is a set of go libraries for building Controllers.

Development

Clone this project, and iterate on changes by running ./test.sh.

Releasing and Versioning

See VERSIONING.md.

Compatibility

Every minor version of controller-tools (CT) has been tested with a specific minor version of client-go. A controller-tools 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-tools for each minor version of client-go and other k8s.io/* dependencies.

The minimum Go version of controller-tools 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 file.

	k8s.io/*, client-go	minimum Go version
CT v0.21	v0.36	1.26
CT v0.20	v0.35	1.25
CT v0.19	v0.34	1.24
