Overview

The Continuous Integration and Continuous Deployment (CI/CD) workflow automates the process of software delivery and infrastructure changes. In the context of the gitlab-org/... project, the CI/CD workflow can be set up using GitLab CI/CD features to build, test, and deploy your code in a streamlined manner.

Checking for CI/CD Setup

Before diving into the CI/CD workflow, verify whether CI/CD is already set up in the project. You can do this by checking for the presence of a .gitlab-ci.yml file in the root directory of the repository. If it exists, proceed to the next section. If it does not exist, CI/CD is not yet set up.

Next Steps for CI/CD Setup

To set up CI/CD in the project, you need to create a .gitlab-ci.yml file. Below are the steps to create a simple CI/CD configuration:

1. Create a .gitlab-ci.yml file in the root of the repository.

2. Define the stages of your CI/CD pipeline. Common stages include build, test, and deploy. Here is a basic example:

   stages:
     - build
     - test
     - deploy
   

3. Configure jobs for each stage. Each job corresponds to a specific task within the stage. For example:

   build_job:
     stage: build
     script:
       - echo "Building the project..."
       - make build
   
   test_job:
     stage: test
     script:
       - echo "Running tests..."
       - make test
   
   deploy_job:
     stage: deploy
     script:
       - echo "Deploying application..."
       - make deploy
   

4. Commit the changes to your repository. The GitLab CI/CD runner will automatically detect the .gitlab-ci.yml file and start the pipeline on your next commit.

Example Pipeline

Here is a complete example of a .gitlab-ci.yml file:

stages:
  - build
  - test
  - deploy

build_job:
  stage: build
  script:
    - echo "Starting build process..."
    - mkdir build
    - cp -r src/* build/

test_job:
  stage: test
  script:
    - echo "Running unit tests..."
    - cd build
    - make test

deploy_job:
  stage: deploy
  script:
    - echo "Deploying to production server..."
    - scp -r build/* user@server:/path/to/deploy/

In this example, the pipeline consists of three stages: build, test, and deploy. Each job includes scripts that will execute specific commands within its defined stage.

Summary

If the project does not have CI/CD set up, creating a .gitlab-ci.yml file in the root directory and defining the necessary stages and jobs will enable the CI/CD workflow. Utilize the provided examples to kickstart the process. Ensure to customize the commands in the scripts according to the specific needs of your project.
