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

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

This project uses Go modules to manage its dependencies, so feel free to work from outside of your GOPATH. However, if you'd like to continue to work from within your GOPATH, please export GO111MODULE=on.

See VERSIONING.md.

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.
