```
### Release Commit (For RPM and DEB)

Commit the changes and push the branch.

```
git commit -av -m "Release $VERSION-1"
git push
git push origin 2.7
```

Gitlab will now build snapshot packages based on the tag `v2.7.0` of Icinga Web 2.

**Note for major releases**: Update release branch to latest.
### Package Tests

```
git checkout release && git pull && git merge master && git push
```
In order to test the created packages you can download a job's artifacts:

**Note for minor releases**: Cherry-pick the release commit into master.
Visit [git.icinga.com](https://git.icinga.com/packaging/rpm-icingaweb2)
and navigate to the respective pipeline under `CI / CD -> Pipelines`.

```
git checkout master && git pull && git cherry-pick release && git push
```
There click on the job you want to download packages from:

![Pipeline Jobs](doc/res/gitlab-rpm-package-pipeline-jobs.png "Pipeline Jobs")

#### DEB with dch on macOS
The job's output appears. On the right-hand sidebar you can browse its artifacts:

```
docker run -v `pwd`:/mnt/packaging -ti ubuntu:bionic bash
![Job Artifacts](doc/res/gitlab-job-artifacts.png "Job Artifacts")

apt-get update && apt-get install git ubuntu-dev-tools vim -y
cd /mnt/packaging
Once there, navigate to `build/RPMS/noarch` where you'll find the packages.

git config --global user.name "Eric Lippmann"
git config --global user.email "eric.lippmann@icinga.com"
### Release Packages

VERSION=2.6.3
To build release packages and upload them to [packages.icinga.com](https://packages.icinga.com)
tag the release commit and push it.

./dch $VERSION-1 "Update to $VERSION"
```
git tag -s 2.7.0-1
git push origin 2.7.0-1
```
