## Preparations <a id="preparations"></a>

Specify the release version.

```
VERSION=1.0.0
```

Add your signing key to your Git configuration file, if not already there.

```
vim $HOME/.gitconfig

[user]
        email = noah.hilverling@icinga.com
        name = Noah Hilverling
        signingKey = "CE23E835630F89D9"
```

### Issues <a id="issues"></a>

Check issues at https://github.com/icinga/icingadb

### Backport Commits <a id="backport-commits"></a>

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

### Authors <a id="authors"></a>

Update the [.mailmap](.mailmap) and [AUTHORS](AUTHORS) files:

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

## Version <a id="version"></a>

Update the version in `version.go`

## Changelog <a id="changelog"></a>

Edit `CHANGELOG.md`, 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  <a id="git-tag"></a>

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

Create a signed tag (tags/v<VERSION>) 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 origin tags/v$VERSION
```

**For major releases:** Create a new `support` branch:

```
git checkout master
git push

git checkout -b support/1.0
git push -u origin support/1.0
```


## Package Builds  <a id="package-builds"></a>

```
mkdir $HOME/projects/icinga/packaging
cd $HOME/projects/icinga/packaging
```

### RPM Packages  <a id="rpm-packages"></a>

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

### DEB Packages <a id="deb-packages"></a>

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


### Branch Workflow

Checkout `master` and create a new branch.

* For releases use x.x as branch name (e.g. 1.0)
* For releases with revision use x.x.x-n (e.g. 1.0.0-1)


### 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" icingadb.spec

vim icingadb.spec

%changelog
* Fri Mar 13 2020 Noah Hilverling <noah.hilverling@icinga.com> 1.0.0-1
- Release 1.0.1
```

#### DEB and Raspbian Release Preparations

Update file `debian/changelog` and add at the beginning:

```
icingadb (1.0.0-1) icinga; urgency=medium

  * Release 1.0.0

 -- Noah Hilverling <noah.hilverling@icinga.com>  Fri, 13 Mar 2020 10:50:31 +0100
```


### Release Commit

Commit the changes and push the branch.

```
git commit -av -m "Release $VERSION-1"
git push origin 1.0
```

GitLab will now build snapshot packages based on the tag `v1.0.0` of Icinga DB.

### 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-icingadb)
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.

RPM/DEB:

```
git tag -s $VERSION-1 -m "Release v$VERSION-1"
git push origin $VERSION-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 <a id="build-infrastructure"></a>

https://git.icinga.com/packaging/rpm-icingadb/pipelines
https://git.icinga.com/packaging/deb-icingadb/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


## GitHub Release  <a id="github-release"></a>

Create a new release for the newly created Git tag: https://github.com/icinga/icingadb/releases

> Hint: Choose [tags](https://github.com/icinga/icingadb/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.


## Post Release  <a id="post-release"></a>

### Online Documentation  <a id="online-documentation"></a>

> Only required for major releases.

Navigate to `puppet-customer/icinga.git` and do the following steps:

#### Testing

```
git checkout testing && git pull
vim files/var/www/docs/config/icingadb-latest.yml

git commit -av -m "icinga-web: Update docs for Icinga DB"

git push
```

SSH into the webserver and do a manual Puppet dry run with the testing environment.

```
puppet agent -t --environment testing --noop
```

Once succeeded, continue with production deployment.

#### Production

```
git checkout master && git pull
git merge testing
git push
```

SSH into the webserver and do a manual Puppet run from the production environment (default).

```
puppet agent -t
```

#### Manual Generation

SSH into the webserver or ask @bobapple.

```
cd /usr/local/icinga-docs-tools && ./build-docs.rb -c /var/www/docs/config/icingadb-latest.yml
```
