GitLab CI Runner

This is GitLab CI Runner repository, this application run tests but it doesn't coordinate the testing. In the GitLab CI repo you can find the open-source continuous integration server that coordinates the testing.

Requirements

This project is designed for the Linux operating system.

We officially support (recent versions of) these Linux distributions:

• Ubuntu Linux
• Debian/GNU Linux

Mac OSX and other POSIX operating systems are not supported but will work with adaptations.

Under Windows the runner will only work under POSIX compliant environments like Cygwin.

To run GitLab CI we recommend using GitLab 6.0 or higher, for LDAP login this is required.

Install dependencies

Install operating system dependent dependencies:

a) Linux

sudo apt-get update -y
sudo apt-get install -y wget curl gcc libxml2-dev libxslt-dev libcurl4-openssl-dev libreadline6-dev libc6-dev libssl-dev make build-essential zlib1g-dev openssh-server git-core libyaml-dev postfix libpq-dev libicu-dev

b) MacOSX (make sure you have homebrew installed)

sudo brew install icu4c

Install Ruby from source:

a) Linux

mkdir /tmp/ruby && cd /tmp/ruby
curl --progress ftp://ftp.ruby-lang.org/pub/ruby/2.0/ruby-2.0.0-p353.tar.gz | tar xz
cd ruby-2.0.0-p353
./configure --disable-install-rdoc
make
sudo make install

b) Mac OS X (make sure you have the Xcode command line tools installed), UNTESTED

brew update
brew install rbenv
brew install ruby-build
brew install openssl
CC=gcc-4.7 RUBY_CONFIGURE_OPTS="--with-openssl-dir=`brew --prefix openssl` --with-readline-dir=`brew --prefix readline` --with-gcc=gcc-4.7 --enable-shared" rbenv install 2.0.0-p353
echo 'if which rbenv > /dev/null; then eval "$(rbenv init -)"; fi' >> ~/.profile
rbenv global 2.0.0-p353

Setup runners

Create the CI runner user and clone the gitlab-ci-runner repository:

sudo gem install bundler
sudo adduser --disabled-login --gecos 'GitLab CI Runner' gitlab_ci_runner
sudo su gitlab_ci_runner
cd ~/
git clone https://gitlab.com/gitlab-org/gitlab-ci-runner.git
cd gitlab-ci-runner

Install the gems for the runner:

bundle install --deployment

Setup the runner interactively:

bundle exec ./bin/setup

OR

Setup the runner non-interactively:

CI_SERVER_URL=https://ci.example.com REGISTRATION_TOKEN=replaceme bundle exec ./bin/setup

The registration token can be found at: http://gitlab-ci-domain.com/admin/runners, accessible through Header > Runners.

Create an Upstart job (Ubuntu, Centos 6)

exit;
cd /home/gitlab_ci_runner/gitlab-ci-runner
sudo cp ./lib/support/upstart/gitlab-ci-runner.conf /etc/init.d/

Set up an init.d script (other distributions)

exit;
cd /home/gitlab_ci_runner/gitlab-ci-runner
sudo cp ./lib/support/init.d/gitlab_ci_runner /etc/init.d/gitlab-ci-runner
sudo chmod +x /etc/init.d/gitlab-ci-runner
sudo update-rc.d gitlab-ci-runner defaults 21 

Run

Using the system service with Upstart/init.d script:

sudo service gitlab-ci-runner start

OR

Manually:

sudo su gitlab_ci_runner
cd /home/gitlab_ci_runner/gitlab-ci-runner
bundle exec ./bin/runner

Update

In order to update the runner to a new version just go to runner directory and do next:

sudo su gitlab_ci_runner
cd ~/gitlab-ci-runner
git fetch
git checkout VERSION_YOU_NEED # Ex. v4.0.0
bundle

And restart runner

Easily add Runners to existing GitLab CI

GitLab.com uses GitLab-CI to test our own builds. To quickly spin up some extra runners in time of need, we have setup a runner as described above, with all the relevant dependencies for our builds and have taken a snapshot of this runner.

To quickly add a runner, have the registration token at hand and:

• instantiate a new VPS with the snapshot gitlab-ci-runner-2gb-2gbswap
• bundle exec ./bin/setup
• sudo service gitlab-ci-runner start

Now the runner will start to pick up builds automatically. When you are done with it, you can destroy the VPS without worrying about anything. For testing GitLab itself, use of a runner with >= 2GB RAM is recommended.
