How To Set Up Continuous Integration Pipelines with GitLab CI on Ubuntu 16.04

Continuous integration (CI) is an important part of modern software development, allowing developers to continuously test and deploy their code. GitLab CI is a popular tool for implementing CI pipelines, and in this tutorial, we will show you how to set up a GitLab CI pipeline on an Ubuntu 16.04 server.

Prerequisites

Before you begin, you will need the following:

  • An Ubuntu 16.04 server
  • A GitLab account
  • A Git repository with a codebase to test and deploy

Step 1: Install GitLab CI Runner

The first step in setting up a GitLab CI pipeline is to install the GitLab CI Runner on your Ubuntu 16.04 server. This can be done by following the steps outlined in the GitLab documentation.

Step 2: Configure GitLab CI Runner

Once the GitLab CI Runner is installed, you will need to configure it to work with your GitLab account. This can be done by following the steps outlined in the GitLab documentation.

Step 3: Create a .gitlab-ci.yml File

The next step is to create a .gitlab-ci.yml file in the root directory of your Git repository. This file will define the stages and jobs of your CI pipeline. For example:


stages:
  - build
  - test
  - deploy

build_job:
  stage: build
  script:
    - echo "Building..."
  artifacts:
    paths:
      - build/

test_job:
  stage: test
  script:
    - echo "Testing..."
  dependencies:
    - build_job

deploy_job:
  stage: deploy
  script:
    - echo "Deploying..."
  dependencies:
    - test_job

This YAML file defines three stages: build, test, and deploy. The build_job stage runs the "Building..." script, saves any artifacts to the "build/" directory, and passes the artifacts to the test_job stage. The test_job stage runs the "Testing..." script and depends on the build_job stage. Finally, the deploy_job stage runs the "Deploying..." script and depends on the test_job stage.

Step 4: Add GitLab CI Configuration to Your Git Repository

Once you have created the .gitlab-ci.yml file, you will need to add it to your Git repository and push it to GitLab. This can be done using the following commands:


$ git add .gitlab-ci.yml
$ git commit -m "Add GitLab CI configuration"
$ git push
