Kubernetes Release

Kubernetes Release

This repo contains the tooling and infrastructure to create Kubernetes releases from the kubernetes/kubernetes main repository.

Intro

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.

Tools

Most tools in this repo run by default in mock mode to allow for ease in development and testing.

Tools	Description
`gcbmgr`	Google Cloud Builder Manager: This is the main entry point for release managers for producing releases. All release types can be staged and later released using this method.
`anago`	Release Tool: The main driver for creating staged builds and releases. This is what runs inside GCB after a job is submitted using `gcbmgr`.
`branchff`	Fast-forward branching helper: A tool used to pull new patches onto the release branch.
`find_green_build`	Asks Jenkins for a good build to use.
`release-notes`	Scrape GitHub for release notes. See Release Notes Gathering for more information.
`prin`	To show release tags of a particular PR or commit.
`changelog-update`	Updates CHANGELOG.md version entries by rescanning github for text and label changes.
`push-build.sh`	Pushes a developer build or CI Jenkins build up to GCS.
`script-template`	Generates a script template in the kubernetes/release ecosystem.
`testgridshot`	Screenshots failing testgrid dashboards and creates a markdown stub that can be copied and pasted into a GitHub issue comment. This makes it easier to create comments like this as part of the release process.

For information on how to use gcbmgr, anago and branchff, see the Branch Manager Handbook

Building Linux Packages

For Debian

You can build the deb packages in a Docker container like this:

docker build --tag=debian-packager debian
docker run --volume="$(pwd)/debian:/src" debian-packager

The build runs for a while, after it's done you will find the output in debian/bin.

For Fedora, CentOS, Red Hat Enterprise Linux

You can build the rpm packages in a Docker container with:

cd rpm
./docker-build.sh

Resulting rpms, and a pre-generated yum repository will be generated in rpm/output/x86_64.
