Apache Ignite 3 Release Procedure

This document describes the current procedure for preparing an Ignite 3 release.

Prerequisites

  1. Create a GPG key, upload it to a keyserver, and locate its ID. More details here: https://infra.apache.org/openpgp.html
  2. Checkout Apache distribution directories: 
    svn checkout https://dist.apache.org/repos/dist/dev/ignite dist-dev
svn checkout https://dist.apache.org/repos/dist/release/ignite dist-release
  3. Provide your Apache credentials to Maven (required for uploading to Apache Nexus): 
    <settings xmlns="http://maven.apache.org/SETTINGS/1.0.0"
          xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
          xsi:schemaLocation="http://maven.apache.org/SETTINGS/1.0.0 https://maven.apache.org/xsd/settings-1.0.0.xsd">
  <servers>
    <server>
      <id>apache.staging</id>
      <username>USERNAME</username>
      <password>PASSWORD</password>
    </server>
  </servers>
</settings>

For all the commands going forward:

  • Replace {version} with the version number being released.
  • Replace {rc} with the current sequential number of the release candidate.
  • Replace {gpg} with your GPG key ID.
  • Replace {dist.dev} with the local path to the development distribution directory.
  • Replace {dist.release} with the local path to the release distribution directory.

Preparing the Release

  1. Go to the project home folder.
  2. Create a Git tag: 
    git tag -a {version}-rc{rc} -m "{version}-rc{rc}"
git push --tags
  3. Build the project, sign the artifact and create a staging repository: 
    mvn clean verify gpg:sign deploy:deploy -Dgpg.keyname={gpg} [-DskipTests]
  4. Login to the Apache Nexus and close the new repository: https://repository.apache.org/#stagingRepositories
  5. Create an empty folder under the development distribution directory: 
    rm -rf {dist.dev}/{version}-rc{rc}
mkdir {dist.dev}/{version}-rc{rc}
  6. Create a source code package: 
    git archive --prefix=apache-ignite-{version}-src/ -o target/apache-ignite-{version}-src.zip HEAD
  7. Switch to the target folder: 
    cd target
  8. Create checksums and sign ZIP packages: 
    gpg -a -u {gpg} -b apache-ignite-{version}-src.zip
gpg -a -u {gpg} -b apache-ignite-{version}.zip
gpg --print-md SHA512 apache-ignite-{version}-src.zip > apache-ignite-{version}-src.zip.sha512
gpg --print-md SHA512 apache-ignite-{version}.zip > apache-ignite-{version}.zip.sha512
  9. Copy ZIP packages along with checksums and signatures to the development distribution directory: 
    cp apache-ignite-{version}-src.zip apache-ignite-{version}-src.zip.asc apache-ignite-{version}-src.zip.sha512 \
   apache-ignite-{version}.zip apache-ignite-{version}.zip.asc apache-ignite-{version}.zip.sha512  \
   /Users/vkulichenko/GridGain/dist-dev/{version}-rc{rc}
  10. Commit ZIP packages:
cd {dist.dev}
svn add {version}-rc{rc}
svn commit -m “Apache Ignite {version} RC{rc}”
  1. Put the release on a vote on the developers mailing list.

Finalizing the Release

Perform the following actions ONLY after the vote is successful and closed.

  1. Login to the Apache Nexus and release the staging repository: https://repository.apache.org/#stagingRepositories
  2. Create an empty folder under the release distribution directory: 
    rm -rf {dist.release}/{version}
mkdir {dist.release}/{version}
  3. Copy ZIP packages along with checksums and signatures to the release distribution directory: 
    cp {dist.dev}/{version}-rc{rc}/* {dist.release}/{version}
  4. Commit ZIP packages: 
    cd {dist.release}
svn add {version}
svn commit -m “Apache Ignite {version}”
