Generate OpenGPG Key
You should get a signing key, keep it in a safe place, upload the public key to apache, and build a web of trust.

Subject: Preparing Ambari X.Y.Z branch
Hi developers and PMCs,
I am proposing cutting a new branch branch-X.Y for Ambari X.Y.Z on __________ as per the outlined tasks in the Ambari Feature + Roadmap page (https://cwiki.apache.org/confluence/pages/viewpage.action?pageId=30755705).
After making the branch, we (i.e., development community) should only accept blocker or critical bug fixes into the branch and harden it until it meets a high enough quality bar.
If you have a bug fix, it should first be committed to trunk, and after ensuring that it does not break any tests (including smoke tests), then it should be integrated to the Ambari branch-X.Y
If you have any doubts whether a fix should be committed into branch-X.Y, please email me for input at ____________
Stay tuned for updates on the release process.
Thanks |
Create the release branch
Create a branch for a release using branch-X.Y (ex: branch-2.1) as the name of the branch.
Note: Going forward, we should be creating branch-{majorVersion}.{minorVersion), so that the same branch can be used for maintenance releases.
Checkout the release branch
Code Block |
---|
|
git checkout branch-X.Y |
Update Ambari REST API docs
Starting with Ambari's {{trunk
}} branch as of Ambari 2.8, the release manager should generate documentation from existing source code. The documentation should be checked back into the branch before performing the release.

# Generate the following artifacts:
# - Configuration markdown at docs/configuration/index.md
# - swagger.json and index.html at docs/api/generated/
cd ambari-server/
mvn clean compile exec:java@configuration-markdown test -Drat.skip -Dcheckstyle.skip -DskipTests -Dgenerate.swagger.resources
# Review and Commit the changes to branch-X.Y
git commit |
Update release version
Make sure once Once the branch is has been created, the release version is set as appropriate. Make sure that all versions are updated. Commit the changes to the release branch.must be set and committed. The changes should be committed to the release branch.
Ambari 2.8+
Starting with Ambari 2.8, the build process relies on Maven 3.5+ which allows the use of the ${revision}
tag. This means that the release version can be defined once in the root pom.xml
and then inherited by all submodules. In order to build Ambari with a specific build number, there are two methods:
mvn -Drevision=2.8.0.0.0 ...
- Editing the root
pom.xml
to include the new build number
To be consistent with prior releases, the pom.xml
should be updated in order to contain the new version.

Ambari 2.7 and Earlier Releases (Deprecated)
Older Ambari branches still required that you update every pom.xml

If this is the first time you have taken release management responsibilities, make sure to update the KEYS file and commit the updated KEYS in both the ambari trunk branch and the release branch. Also in addition to updating the KEYS file in the tree, you also need to push the KEYS file to https://dist.apache.org/repos/dist/release/ambari/
Code Block |

title | Update the KEYS File |

#update the KEYS file

gpg2 --armor --export jluniya@apache.org >> KEYS
# commit the changes to both trunk and new release branch
git commit
# push the updated KEYS file to https://dist.apache.org/repos/dist/release/ambari/.
# Only PMCs members can do this 'svn' step.
svn co https://dist.apache.org/repos/dist/release/ambari ambari_svn
