Backport Commits

For minor versions you need to manually backports any and all commits from the master branch which should be part of this release.

Authors

git checkout master
git log --use-mailmap | grep '^Author:' | cut -f2- -d' ' | sort | uniq > AUTHORS

Version

Update the version:

sed -i "s/Version: .*/Version: $VERSION/g" VERSION

Changelog

Choose the most important issues and summarize them in multiple groups/paragraphs. Provide links to the mentioned issues/PRs. At the start include a link to the milestone's closed issues.

Git Tag

git commit -v -a -m "Release version $VERSION"

Create a signed tag (tags/v) on the master branch (for major releases) or the support branch (for minor releases).

git tag -s -m "Version $VERSION" v$VERSION

Push the tag:

git push --tags

For major releases: Create a new support branch:

git checkout master
git push

git checkout -b support/2.12
git push -u origin support/2.12

Package Builds

mkdir $HOME/dev/icinga/packaging
cd $HOME/dev/icinga/packaging

RPM Packages

git clone git@git.icinga.com:icinga/rpm-icinga2.git && cd rpm-icinga2

DEB Packages

git clone git@git.icinga.com:packaging/deb-icinga2.git && cd deb-icinga2

Windows Packages

git clone git@git.icinga.com:icinga/windows-icinga2.git && cd windows-icinga2

Branch Workflow

Checkout master and create a new branch.

• For releases use x.x[.x] as branch name (e.g. 2.11 or 2.11.1)
• For releases with revision use x.x.x-n (e.g. 2.11.0-2)

Switch Build Type

Edit file .gitlab-ci.yml and comment variable ICINGA_BUILD_TYPE out.

variables:
  ...
  #ICINGA_BUILD_TYPE: snapshot
  ...

Commit the change.

git commit -av -m "Switch build type for $VERSION-1"

RPM Release Preparations

Set the Version, revision and %changelog inside the spec file:

sed -i "s/Version:.*/Version:        $VERSION/g" icinga2.spec

vim icinga2.spec

%changelog
* Thu Sep 19 2019 Michael Friedrich <michael.friedrich@icinga.com> 2.11.0-1
- Update to 2.11.0

DEB and Raspbian Release Preparations

Update file debian/changelog and add at the beginning:

  * Release 2.11.0

 -- Michael Friedrich <michael.friedrich@icinga.com>  Thu, 19 Sep 2019 10:50:31 +0200

Release Commit

Commit the changes and push the branch.

git commit -av -m "Release $VERSION-1"
git push origin 2.11

GitLab will now build snapshot packages based on the tag v2.11.0 of Icinga 2.

Package Tests

In order to test the created packages you can download a job's artifacts:

Visit git.icinga.com and navigate to the respective pipeline under CI / CD -> Pipelines.

There click on the job you want to download packages from.

The job's output appears. On the right-hand sidebar you can browse its artifacts.

Once there, navigate to build/RPMS/noarch where you'll find the packages.

Release Packages

To build release packages and upload them to packages.icinga.com tag the release commit and push it.

RPM/DEB/Raspbian:

git tag -s $VERSION-1 -m "Release v$VERSION-1"
git push origin $VERSION-1

Windows:

git tag -s $VERSION -m "Release v$VERSION"
git push origin $VERSION

Now cherry pick the release commit to master so that the changes are transferred back to it.

Attention: Only the release commit. NOT the one switching the build type!

• Verify package build changes for this version.
• Test the snapshot packages for all distributions beforehand.

Once the release repository tags are pushed, release builds are triggered and automatically published to packages.icinga.com

Release Tests

• Test DB IDO with MySQL and PostgreSQL.
• Provision the vagrant boxes and test the release packages.
• Test the setup wizard inside a Windows VM.
• Start a new docker container and install/run icinga2.

wget -O - https://packages.icinga.com/icinga.key | apt-key add -

. /etc/os-release; if [ ! -z ${UBUNTU_CODENAME+x} ]; then DIST="${UBUNTU_CODENAME}"; else DIST="$(lsb_release -c| awk '{print $2}')"; fi; \
 echo "deb https://packages.icinga.com/ubuntu icinga-${DIST} main" > \
 /etc/apt/sources.list.d/${DIST}-icinga.list
 echo "deb-src https://packages.icinga.com/ubuntu icinga-${DIST} main" >> \
