Kubernetes Release Tooling

This repo contains the tooling and infrastructure configurations for creating Kubernetes releases from the kubernetes/kubernetes main repository.

There are several scripts and helpers in this repository a Release Manager will find useful when managing all kinds of releases (alpha, beta, official, rc) across branches.

Golang-based tools can be built via the compile-release-tools script. Individual tools can be installed via go install k8s.io/release/cmd/$TOOL@latest.

Release Creation

If you create a new release for this repository, then the goreleaser GitHub action will attach all available binary artifacts to it automatically. To publish those artifacts to our k8s-artifacts-sig-release GCS bucket, run the following kpromo command for the new $TAG:

kpromo gh \
    --org kubernetes \
    --repo release \
    --bucket k8s-artifacts-sig-release \
    --tags $TAG

The release notes can be generated by using the release-notes tool from this repository, which is also available as binary artifact:

release-notes \
    --org kubernetes \
    --repo release \
    --required-author "" \
    --start-rev $PREVIOUS_TAG \
    --end-rev $TAG \
    --output release-notes.md
