krel is the new golang based tool for managing releases.
The purpose of krel is to provide a toolkit for managing the different steps needed to create Kubernetes Releases. This includes manually executed tasks like generating the Release Notes during the release cycle and performing automated tasks like pushing the Kubernetes release artifacts to Google Cloud Storage.
Either download the latest version of krel by using the hack/get-krel script:
./hack/get-krelOr compile krel by running the compile-release-tools script from the root of this repo:
./compile-release-tools krelOr run the following command in the terminal:
