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:

Access to Apache Nexus repository

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

  1. You log in with your Apache account.
  2. Confirm you have appropriate access by finding org.apache.flink under Staging Profiles.
  3. Navigate to your Profile (top right dropdown menu of the page).
  4. Choose User Token from the dropdown, then click Access User Token. Copy a snippet of the Maven XML configuration block.

  5. Insert this snippet twice into your global Maven settings.xml file, typically ${HOME}/.m2/settings.xml. The end result should look like this, where TOKEN_NAME and TOKEN_PASSWORDare your secret tokens:

    Code Block
    languagexml
    titlesettings.xml
    <settings>
   <servers>
     <server>
       <id>apache.releases.https</id>

Website development setup

Get ready for updating the Flink website by following the website development instructions.

Create a new version in JIRA

When contributors resolve an issue in JIRA, they are tagging it with a release that will contain their changes. With the release currently underway, new issues should be resolved against a subsequent future release. Therefore, you should create a release item for this subsequent release, as follows:

  1. In JIRA, navigate to the Flink > Administration > Versions.
  2. Add a new release: choose the next minor version number compared to the one currently underway, select today’s date as the Start Date, and choose Add.

Triage release-blocking issues in JIRA

There could be outstanding release-blocking issues, which should be triaged before proceeding to build a release candidate. We track them by assigning a specific Fix version field even before the issue resolved.

The list of release-blocking issues is available at the version status page. Triage each unresolved issue with one of the following resolutions:

  • If the issue has been resolved and JIRA was not updated, resolve it accordingly.
  • If the issue has not been resolved and it is acceptable to defer this until the next release, update the Fix Version field to the new version you just created. Please consider discussing this with stakeholders and the dev@ mailing list, as appropriate.
  • If the issue has not been resolved and it is not acceptable to release until it is fixed, the release cannot proceed. Instead, work with the Flink community to resolve the issue.

Review Release Notes in JIRA

JIRA automatically generates Release Notes based on the Fix Version field applied to issues. Release Notes are intended fo users (not Flink committers/contributors). You

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

...

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

We now need to do several things:


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 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

...

Code Block
languagebash
titlePush tag

Note: the official Dockerfiles fetch some artifacts of the target StateFun version from Maven central. After publishing the artifacts, the Maven central repository can take some hours to start serving the new artifacts, so you may want to wait to do this step until you are ready to continue with the "Promote the release" steps below.

Follow the instructions in the flink-statefun-docker repo to build the new Dockerfiles and send an updated manifest to Docker Hub so the new images are built and publishedin the flink-statefun-docker repo to build the new Dockerfiles and send an updated manifest to Docker Hub so the new images are built and published.

Create a new release-${SHORT_RELEASE_VERSION} branch in flink-statefun-playground by forking the dev branch.

Make sure that all statefun versions are updated to the new ${SHORT_RELEASE_VERSION} (grep for occurrences of the old version).
