## Preparations
Specify the release version.
```
VERSION=2.11.0
```
Add your signing key to your Git configuration file, if not already there.
```
vim $HOME/.gitconfig
[user]
email = michael.friedrich@icinga.com
name = Michael Friedrich
signingkey = D14A1F16
```
### Issues
Check issues at https://github.com/Icinga/icinga2
### 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
Update the [.mailmap](.mailmap) and [AUTHORS](AUTHORS) files:
```
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
```
#### Raspbian Packages
```
git clone git@git.icinga.com:icinga/raspbian-icinga2.git && cd raspbian-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.
```yaml
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 2.11.0-1
- Update to 2.11.0
```
#### DEB and Raspbian Release Preparations
Update file `debian/changelog` and add at the beginning:
```
icinga2 (2.11.0-1) icinga; urgency=medium
* Release 2.11.0
-- Michael Friedrich 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](https://git.icinga.com/packaging/rpm-icinga2)
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](https://packages.icinga.com)
tag the release commit and push it.
```
git tag -s 2.11.0-1
git push origin 2.11.0-1
```
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!
## Build Infrastructure
https://git.icinga.com/packaging/rpm-icinga2/pipelines
https://git.icinga.com/packaging/deb-icinga2/pipelines
https://git.icinga.com/packaging/windows-icinga2/pipelines
https://git.icinga.com/packaging/raspbian-icinga2/pipelines
* 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](https://packages.icinga.com/windows/) inside a Windows VM.
* Start a new docker container and install/run icinga2.
### CentOS
```
docker run -ti centos:latest bash
yum -y install https://packages.icinga.com/epel/icinga-rpm-release-7-latest.noarch.rpm
yum -y install epel-release
yum -y install icinga2
icinga2 daemon -C
```
### Ubuntu
```
docker run -ti ubuntu:bionic bash
apt-get update
apt-get -y install apt-transport-https wget gnupg
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" >> \
/etc/apt/sources.list.d/${DIST}-icinga.list
apt-get update
apt-get -y install icinga2

```
## GitHub Release
Create a new release for the newly created Git tag: https://github.com/Icinga/icinga2/releases
> Hint: Choose [tags](https://github.com/Icinga/icinga2/tags), pick one to edit and
> make this a release. You can also create a draft release.
The release body should contain a short changelog, with links
into the roadmap, changelog and blogpost.
## Chocolatey
Navigate to the git repository on your Windows box which
already has chocolatey installed. Pull/checkout the release.
Create the nupkg package (or use the one generated on https://packages.icinga.com/windows):
```
cpack
```
Fetch the API key from https://chocolatey.org/account and use the `choco push`
command line.
```
choco apikey --key xxx --source https://push.chocolatey.org/
choco push Icinga2-v2.11.0.nupkg --source https://push.chocolatey.org/
```
