How to Install GitLab CI on NetBSD

In this tutorial, we will cover the step-by-step process of installing GitLab CI on NetBSD.

Prerequisites

Before we begin, make sure you have the following prerequisites:

• NetBSD server with root access
• Git installed on the server
• Docker installed on the server

Step 1: Install GitLab CI

1. SSH into your NetBSD server as root.

2. Install GitLab CI by running the following command:

# pkg_add gitlab-runner

It will install GitLab CI Runner on your NetBSD server.

Step 2: Register GitLab CI Runner

1. Navigate to your GitLab instance and create a new project.

2. Click on the "Settings" cog in the top right corner and select "CI/CD".

3. Under "Runners", click "Set up a specific Runner manually".

4. Copy the URL and registration token.

5. SSH back into your NetBSD server and run the following command to register your runner:

$ gitlab-runner register

6. Follow the prompts and paste the URL and registration token when prompted.

7. Choose a descriptive name for your runner and select the tags associated with it.

8. Once registered, the runner will be ready to use.

Step 3: Configure GitLab CI Runner

1. Navigate to your NetBSD server and open the GitLab Runner configuration file by running the following command:

$ vi /usr/pkg/etc/gitlab-runner/config.toml

2. Edit the file to match the following example configuration:

concurrent = 1
check_interval = 0

[[runners]]
  name = "netbsd-runner"
  url = "https://gitlab.example.com/"
  token = "xxxxxxxxxxxxxxxxxxxxx"
  executor = "docker"
  environment = ["DOCKER_TLS_CERTDIR=", "DOCKER_CERT_PATH="]
  [runners.docker]
    tls_verify = false
    image = "docker:stable"
    privileged = true
    disable_entrypoint_overwrite = false
    oom_kill_disable = false
    disable_cache = false
    volumes = ["/var/run/docker.sock:/var/run/docker.sock", "/cache"]
    extra_hosts = ["gitlab.example.com:192.168.1.1"]
    shm_size = 0

Note: Replace the name, url, and token values with your GitLab instance details.

3. Save the file and exit.

Step 4: Test GitLab CI Runner

1. Navigate to your GitLab project and create a simple .gitlab-ci.yml file with the following contents:

stages:
  - test
test:
  stage: test
  script:
    - echo "Hello, NetBSD!"

2. Commit the file to the project's master branch.

3. Navigate back to your NetBSD server and start the GitLab Runner by running the following command:

$ gitlab-runner start

4. Verify the runner successfully picks up the job by checking the GitLab CI/CD pipeline.

5. The pipeline should be successful and display the output Hello, NetBSD!.

Congratulations! You have successfully installed GitLab CI on NetBSD and used it to run a basic pipeline.
