  - deploy

  stage: build
    - echo "Building the project..."

  stage: test
    - echo "Running tests..."

  stage: deploy
    - echo "Deploying to production..."

Remember, the order of jobs and their respective stages will dictate the flow of your CI/CD pipeline. It’s crucial to structure them in a way that reflects the lifecycle of your application development.

As you become more familiar with GitLab CI/CD, you’ll expand on this basic template, adding complexity and functionality to suit your project’s needs. But for now, focus on getting a simple pipeline up and running to start reaping the benefits of continuous integration.

Defining Stages and Jobs

In the realm of GitLab CI/CD, stages are like milestones in your pipeline, each comprising one or more jobs that dictate the actual work to be done. Think of stages as the chapters of your CI story, with jobs as the paragraphs fleshing out the narrative. Jobs are the individual tasks or actions performed within each stage of the pipeline, such as compiling code or running tests.

Embracing pipelines means committing to automation and consistency in your development workflow. It’s about ensuring that every code commit is built, tested, and deployed systematically.

When crafting your .gitlab-ci.yml, it’s crucial to define the stages first, which will set the execution order for your jobs. Here’s a simple breakdown:

  • build: Prepare the code
  • test: Verify functionality
  • deploy: Release to production

Each job within these stages should have a clear purpose and be as atomic as possible. For instance, a job in the build stage might compile your code, while a test job could run unit tests. By structuring your pipeline in this way, you ensure a smooth and logical flow from code commit to deployment.

Utilizing Cache and Artifacts to Optimize Builds

In the continuous integration workflow, the efficient use of cache and artifacts is pivotal for optimizing build times and resource usage. Caching build artifacts can drastically reduce the time spent on recompiling unchanged code and downloading dependencies.
