How to Install GitLab CI on OpenBSD

GitLab CI is a continuous integration tool that allows you to automate testing and deployment of your code. In this tutorial, we will explain how to install GitLab CI on OpenBSD.

Prerequisites

Before starting the installation process, make sure that you have the following prerequisites:

• OpenBSD 6.7 or higher
• Root access to your server
• Basic knowledge of the command line

Step 1: Install GitLab Runner

GitLab Runner is the tool that executes CI/CD pipelines. To install GitLab Runner on OpenBSD, follow these steps:

1. Open the terminal and run the following command to download the package source:

$ ftp https://openbsd.cs.toronto.edu/pub/OpenBSD/$(uname -r)/packages/$(uname -m)/gitlab-runner-<version>.tgz

2. Extract the package to the /usr/local/bin directory:

$ tar zxvf gitlab-runner-<version>.tgz -C /usr/local/bin/

3. Create a symlink to the GitLab Runner binary:

$ ln -s /usr/local/bin/gitlab-runner-<version>/gitlab-runner /usr/local/bin/gitlab-runner

Step 2: Install GitLab CI

To install GitLab CI on OpenBSD, follow these steps:

1. Install the Git package:

$ pkg_add git

2. Install the Ruby package:

$ pkg_add ruby

3. Install the Ruby Gems package:

$ pkg_add ruby-gems

4. Install the bundler gem:

$ gem install bundler

5. Create a new GitLab CI directory:

$ mkdir -p /usr/local/gitlab-ci

6. Change to the new directory:

$ cd /usr/local/gitlab-ci

7. Clone the GitLab CI repository:

$ git clone https://gitlab.com/gitlab-org/gitlab-ci.git

8. Change to the gitlab-ci directory:

$ cd gitlab-ci

9. Install the required dependencies:

$ bundle install --deployment --without development test postgres mysql sqlite

Step 3: Configure GitLab CI

To configure GitLab CI on OpenBSD, follow these steps:

1. Copy the example configuration file:

$ cp config/application.yml.example config/application.yml

2. Edit the application.yml file and modify the following settings:

gitlab:
  url: "https://gitlab.example.com"
  app_id: "<APP_ID>"
  app_secret: "<APP_SECRET>"
  # ...

Replace gitlab.example.com with the URL of your GitLab instance. To get the app_id and app_secret, you need to create a GitLab application in the GitLab UI.

3. Create a new GitLab Runner configuration file:

$ cp config/config.toml.example config/config.toml

4. Edit the config.toml file and modify the following settings:

concurrent = 1
check_interval = 0

[[runners]]
  name = "OpenBSD Runner"
  url = "https://gitlab.example.com/"
  token = "<RUNNER_TOKEN>"
  executor = "shell"
  shell = "/bin/ksh"

Replace gitlab.example.com with the URL of your GitLab instance. To get the RUNNER_TOKEN, you need to register a new GitLab Runner in the GitLab UI.

Step 4: Start GitLab CI

To start GitLab CI on OpenBSD, follow these steps:

1. Change to the gitlab-ci directory:

$ cd /usr/local/gitlab-ci/gitlab-ci

2. Start the GitLab CI service:

$ bundle exec rake gitlab:setup RAILS_ENV=production

3. Start the GitLab Runner service:

$ gitlab-runner install --user=gitlab-runner --working-directory=/usr/local/gitlab-ci/gitlab-ci --config=config/config.toml

4. Start the GitLab Runner service:

$ gitlab-runner run --user=gitlab-runner --working-directory=/usr/local/gitlab-ci/gitlab-ci --config=config/config.toml

Congratulations, you have now installed and configured GitLab CI on OpenBSD! You can now use GitLab CI to automate your testing and deployment pipelines.

If you want to self-host in an easy, hands free way, need an external IP address, or simply want your data in your own hands, give IPv6.rs a try!

Alternatively, for the best virtual desktop, try Shells!
