How to do a Kata Containers Release

Hi if you are reading this document you may also want to create a kata Containers Release.

The Kata Containers Release Process is defined in the follwoing documents.

https://github.com/kata-containers/documentation/blob/master/Releases.md

To simply the process of read each release we have created a checklist for it.

https://github.com/kata-containers/documentation/blob/master/Release-Checklist.md

In order to simplify the process of do the Release Checklist we have semi-automated most of the process.

So lets get started.

Requeriments

• Go (https://golang.org/doc/install#)

• hub (https://github.com/github/hub) If you are using github 2FA, configure hub manually creating a file ~/.config/hub

  github.com:
  - user: YOUR_USER
  oauth_token: TOKEN
  protocol: https

  • OBS account with permissions on /home:katacontainers (https://build.opensuse.org/project/subprojects/home:katacontainers)

  • Github permissions to push tags an creates Releases in Kata repositories.

  • GPG configured to sign git tags. https://help.github.com/articles/generating-a-new-gpg-key/

  • Your github should be configured to use your ssh keys (to push to branches). See https://help.github.com/articles/adding-a-new-ssh-key-to-your-github-account/.

    • As alternative you can configure hub to do push and forks with https, git config --global hub.protocol https (Not tested yet) *

Get packaging kata repository.

go get -d github.com/kata-containers/packaging

Start release process

cd ${GOPATH}/src/github.com/kata-containers/packaging
#make sure you are up-to-date.
git pull

1. Bump repositories

cd ${GOPATH}/src/github.com/kata-containers/packaging/release
export NEW_VERSION=X.Y.Z
export BRANCH="master"
./update-repository-version.sh -p ksm-throttler "$NEW_VERSION" "$BRANCH"
./update-repository-version.sh -p proxy "$NEW_VERSION" "$BRANCH"
./update-repository-version.sh -p shim "$NEW_VERSION" "$BRANCH"
./update-repository-version.sh -p runtime "$NEW_VERSION" "$BRANCH"
./update-repository-version.sh -p osbuilder "$NEW_VERSION" "$BRANCH"
./update-repository-version.sh -p agent "$NEW_VERSION" "$BRANCH"

The commands from above will create a github pull request in the Kata projects. Work with the Kata approvers to verify that the CI works and the PR are merged.

2. Create Github tags

After all the PRs from the previous step were done, its time to create github tags.

cd ${GOPATH}/src/github.com/kata-containers/packaging/release
 ./tag_repos.sh -p -b "$BRANCH" tag

This wil create tags for all the Kata Repos.

4. Create Kata Containers Image and upload to Github.

cd ${GOPATH}/src/github.com/kata-containers/packaging/release
./publish-kata-image.sh -p ${NEW_VERSION}

5. Create Kata static binaries tarball and upload to github.

cd ${GOPATH}/src/github.com/kata-containers/packaging/release

./kata-deploy-binaries.sh -p ${NEW_VERSION}

6. Create Kata packages.

cd ${GOPATH}/src/github.com/kata-containers/packaging/obs-packaging
#./create-pkg-branch.sh ${BRANCH}
./gen_versions_txt.sh ${BRANCH}
PUSH=1 OBS_SUBPROJECT="releases:$(uname -m):${BRANCH}" ./build_from_docker.sh ${NEW_VERSION}

7. Create release notes.

cd ${GOPATH}/src/github.com/kata-containers/packaging/release
./runtime-release-notes.sh 1.2.0 1.2.1 > notes.md

Add release notes in github runtime.

9. Announce release.

Publish in Slack and ML that new release is ready.
