Now, add your Apache GPG key to the Flink’s KEYS file in the release repository at dist.apache.org. Follow the instructions listed at the top of these files. (Note: Only PMC members have write access to the release repository. If you end up getting 403 errors ask on the mailing list for assistance.)Configure git to use this key when signing code by giving it your key ID, as follows: PMC member can refer following scripts to add your Apache GPG key to the KEYS in the release repository.

Code Block
languagebash
git config --global user.signingkey 845E6689

You may drop the --global option if you’d prefer to use this key for the current repository only.

You may wish to start gpg-agent to unlock your GPG key only once using your passphrase. Otherwise, you may need to enter this passphrase hundreds of times. The setup for gpg-agent varies based on operating system, but may be something like this:

Code Block
languagebash
eval $(gpg-agent --daemon --no-grab --write-env-file $HOME/.gpg-agent-info)
export GPG_TTY=$(tty)
export GPG_AGENT_INFO

Access to Apache Nexus repository

Configure access to the Apache Nexus repository, which enables final deployment of releases to the Maven Central Repository.

svn co https://dist.apache.org/repos/dist/release/flink flink-dist-release-repo
cd flink-dist-release-repo
(gpg --list-sigs <YOUR_KEY_ID> && gpg --armor --export <YOUR_KEY_ID>) >> KEYS
svn ci -m "[flink] Add <YOUR_NAME>'s public key"

Configure git to use this key when signing code by giving it your key ID, as follows:

Verify that a Release Build Works

Run mvn -Papache-release,run-e2e-tests clean install to ensure that the build processes that are specific to that profile are in good shape.

...

Code Block
languagebash
RELEASE_VERSION="2.1.0"
SHORT_RELEASE_VERSION="2.1"
CURRENT_SNAPSHOT_VERSION="$SHORT_RELEASE_VERSION-SNAPSHOT"
NEXT_SNAPSHOT_VERSION="2.2-SNAPSHOT"
SHORT_NEXT_SNAPSHOT_VERSION="2.2"
SHORT_PREVIOUS_RELEASE_VERSION="2.0"

If you are doing a new major/minor release (e.g. 2.0.0, 2.1.0), check out the version of the codebase from which you start the release. This may be HEAD of the master branch branch.

Create a branch for the new version that we want to release before updating the master branch to the next development version:

Code Block
languagebash
$ git checkout master
$ PREVIOUS_RELEASE_VERSION=$SHORT_PREVIOUS_RELEASE_VERSION CURRENT_RELEASE_VERSION=$SHORT_RELEASE_VERSION tools/releasing/update_playground_links.sh
$ RELEASE_VERSION=$SHORT_RELEASE_VERSION tools/releasing/create_release_branch.sh
$ git checkout master
$ OLD_VERSION=$CURRENT_SNAPSHOT_VERSION NEW_VERSION=$NEXT_SNAPSHOT_VERSION tools/releasing/update_branch_version.sh
$ git checkout release-$SHORT_RELEASE_VERSION

...

Next, for major releases, some configuration for our documentation builds needs to be manually updated, in the docs/_config.ymltoml file:, as listed below.

Code Block
languagebash
version: $RELEASE_VERSION
version_title: $SHORT_RELEASE_VERSION
github_branch: release-$SHORT_RELEASE_VERSION
baseurl: //cibaseURL = '//nightlies.apache.org/projects/flink/flink-statefun-docs-release-$SHORT_RELEASE_VERSION
javadocs_baseurl: //ci.apache.org/projects/flink/flink-statefun-docs-release-'
IsStable = true
Version = "$RELEASE_VERSION"
VersionTitle = "$SHORT_RELEASE_VERSION
is_stable: true

After updating the docs configuration and pushing the new major release branch, as the last step you should also update the documentation build bot to also build the documentation for the new release branch. Check Managing Documentation on details on how to do that. You may also want to manually trigger a build to make the changes visible as soon as possible.

The rest of this guide assumes that commands are run in the root of a repository on the branch of the release version with the above environment variables set.

Build a release candidate

The core of the release process is the build-vote-fix cycle. Each cycle produces one release candidate. The Release Manager repeats this cycle until the community approves one release candidate, which is then finalized.

Build and stage Java and Python artifacts

Set up a few environment variables to simplify Maven commands that follow. This identifies the release candidate being built. Start with RC_NUM equal to 1 and increment it for each candidate.

Code Block
languagebash
RC_NUM="1"
TAG="release-${RELEASE_VERSION}-rc${RC_NUM}"

Now, create a candidate branch

Code Block
languagebash
RC_NUM="1"
TAG="release-${RELEASE_VERSION}-rc${RC_NUM}"

Now, create a candidate branch:

Code Block
languagebash
$ OLD_VERSION=$CURRENT_SNAPSHOT_VERSION NEW_VERSION=$RELEASE_VERSION RELEASE_CANDIDATE=$RC_NUM tools/releasing/create_release_branch.sh

Tag the release commit:

Code Block
git tag -s ${TAG} -m "${TAG}"

We now need to do several things:

  • Create the source release archive
  • Create the Python artifacts
  • Deploy jar artifacts to the Apache Nexus Repository, which is the staging area for deploying the jars to Maven Central

First, we build the source release:

Code Block
languagebash
$ RELEASE_VERSION=$RELEASE_VERSION tools/releasing/create_source_release.sh

Next, we build the Python artifacts:

Code Block
languagebash
$ RELEASE_VERSION=$RELEASE_VERSION tools/RELEASE_CANDIDATE=$RC_NUM tools/releasing/create_pythonrelease_sdk_release.sh

You will be able to find the built source and Python release artifacts under the "release/" folder created under the project root directory.

Finally, we stage the maven artifacts:

Code Block
languagebash
$branch.sh
OLD_VERSION=$CURRENT_SNAPSHOT_VERSION NEW_VERSION=$RELEASE_VERSION tools/releasing/deployupdate_stagingbranch_jarsversion.sh

Review all staged artifacts (https://repository.apache.org/). They should contain all relevant parts for each module, including pom.xml, jar, test jar, source, test source, javadoc, etc. Carefully review any new artifacts.

Close the staging repository on Apache Nexus. When prompted for a description, enter “Apache Flink Stateful Functions, version X, release candidate Y”.

Stage source and binary releases on dist.apache.org

Copy the source release to the dev repository of dist.apache.org.

...

Tag the release commit:

Code Block
git tag -s ${TAG} -m "${TAG}"
git tag -s "statefun-sdk-go/v${RELEASE_VERSION}-rc${RC_NUM}" -m "${TAG}"

We now need to do several things:

  • Create the source release archive
  • Create the Python artifacts
  • Deploy jar artifacts to the Apache Nexus Repository, which is the staging area for deploying the jars to Maven Central

First, we build the source release:

Code Block
languagebash

...

svn checkout https://dist.apache.org/repos/dist/dev/flink --depth=immediates
$ RELEASE_VERSION=$RELEASE_VERSION tools/releasing/create_source_release.sh

Next, we build the Python artifacts

...

:

Code Block
languagebash

...

$ RELEASE_VERSION

...

Copy all release distributions, hashes, and GPG signature:
Code Block
mv <flink-statefun-dir>/release/* flink/flink-statefun-${RELEASE_VERSION}-rc${RC_NUM}
=$RELEASE_VERSION tools/releasing/create_python_sdk_release.sh

You will be able to find the built source and Python release artifacts under the "release/" folder created under the project root directory.

Finally, we stage the maven artifacts:

...

Code Block
languagebash

...

cd flink 
svn add flink-statefun-${RELEASE_VERSION}-rc${RC_NUM}
svn commit -m "Apache Flink Stateful Functions, version ${RELEASE_VERSION}, release candidate ${RC_NUM}"

...

Verify that files are present

$ tools/releasing/deploy_staging_jars.sh

Review all staged artifacts (https://repository.apache.org/). They should contain all relevant parts for each module, including pom.xml, jar, test jar, source, test source, javadoc, etc. Carefully review any new artifacts.

Close the staging repository on Apache Nexus. When prompted for a description, enter “Apache Flink Stateful Functions, version X, release candidate Y”.

Stage source and binary releases on dist.apache.org

Copy the source release to the dev repository of dist.apache.org.

  1. If you have not already, check out the Flink section of the dev repository on dist.apache.org via Subversion. In a fresh directory:

    Code Block
    languagebash
    svn checkout https://dist.apache.org/repos/dist/dev/flink --depth=immediates


  2. Make a directory for the new release:

    Code Block
    languagebash
    mkdir flink/flink-statefun-${RELEASE_VERSION}-rc${RC_NUM}
    Copy all release distributions, hashes, and GPG signature:
    Code Block
    mv <flink-statefun-dir>/release/* flink/flink-statefun-${RELEASE_VERSION}-rc${RC_NUM}


  3. Add and commit all the files.

    Code Block
    languagebash
    cd flink 
    svn add flink-statefun-${RELEASE_VERSION}-rc${RC_NUM}
    svn commit -m "Apache Flink Stateful Functions, version ${RELEASE_VERSION}, release candidate ${RC_NUM}"


  4. Verify that files are present

(Push the release tag)

If you haven't pushed the release tag yet, here's the command:

Code Block
languagebash
titlePush tag
git push <remote> refs/tags/release-${RELEASE_VERSION}-rc${RC_NUM}
git push <remote> refs/tags/statefun-sdk-go/v${RELEASE_VERSION}-rc${RC_NUM}


Propose a pull request for website updates

The final step of building the candidate is to propose a website pull request.

Start by updating the variables for the latest released version in the top-level _config.yml, and list the new release in downloads.md, linking to the source code download and the Release Notes in JIRA. Also add a new blog entry announcing the release in _posts.

Finally, propose a pull request with these changes. (Don’t merge before finalizing the release.)

Checklist to proceed to the next step

  1. Maven artifacts deployed to the staging repository of repository.apache.org
  2. Source distribution deployed to the dev repository of dist.apache.org
  3. Website pull request proposed to list the release
  4. Check docs/config.toml to ensure that
    • the version constants refer to the new version
    • the baseurl does not point to flink-statefun-docs-master  but flink-statefun-docs-release-X.Y instead

You can (optionally) also do additional verification by:

  1. Check hashes (e.g. shasum -c *.sha512)
  2. Check signatures (e.g. gpg --verify flink-statefun-1.2.3-source-release.tar.gz.asc flink-statefun-1.2.3-source-release.tar.gz)
  3. grep for legal headers in each file.

For a new bugfix version remove all release files for previous bugfix releases in the same series, e.g., when releasing 1.7.1, remove the 1.7.0 release.

  1. If you have not already, check out the Flink section of the release repository on dist.apache.org via Subversion. In a fresh directory:

    Code Block
    languagebash
     svn checkout https://dist.apache.org/repos/dist/release/flink

Git tag

Create a new Git tag for the released version by copying the tag for the final release candidate, as follows:



Code Block
git tag -s "release-${RELEASE_VERSION}

...

" refs/tags/${TAG} -m "

...

Release Stateful Functions ${RELEASE_VERSION

...

}"

For the GoLang SDK we we also need to push another release tag

Code Block
git tag -s "statefun-sdk-go/v${RELEASE_VERSION}" refs/tags/${TAG} -m "Release Stateful Functions ${RELEASE_VERSION}"

Don't forget to push the tags via
Code Block
git push <remote> refs/tags/release-${RELEASE_VERSION}
git push <remote> refs/tags/statefun-sdk-go/v${RELEASE_VERSION}

Delete the RC tags on the remote repository

Code Block
git push --delete <remote> refs/tags/${TAG}
git push --delete <remote> refs/tags/statefun-sdk-go/v${RELEASE_VERSION}-rc${RC_NUM
