Overview

Create comprehensive GitLab CI/CD pipelines that automate building, testing, and deployment using GitLab Runner infrastructure and container execution.

When to Use

GitLab repository CI/CD setup
Multi-stage build pipelines
Docker registry integration
Kubernetes deployment
Review app deployment
Cache optimization
Dependency management

Quick Start

Minimal working example:

# .gitlab-ci.yml
image: node:18-alpine

variables:
  DOCKER_DRIVER: overlay2
  FF_USE_FASTZIP: "true"

stages:
  - lint
  - test
  - build
  - security
  - deploy-review
  - deploy-prod

cache:
  key: ${CI_COMMIT_REF_SLUG}
  paths:
    - node_modules/
    - .npm/

lint:
  stage: lint
  script:
    - npm install
// ... (see reference guides for full implementation)

Best Practices

✅ DO

Use stages to organize pipeline flow
Implement caching for dependencies
Use artifacts for test reports
Set appropriate cache keys
Implement conditional execution with only and except
Use needs: for job dependencies
Clean up artifacts with expire_in
Use Docker for consistent environments
Implement security scanning stages
Set resource limits for jobs
Use merge request pipelines

❌ DON'T

Run tests serially when parallelizable
Cache everything unnecessarily
Leave large artifacts indefinitely
Store secrets in configuration files
Run privileged Docker without necessity
Skip security scanning
Ignore pipeline failures
Use only: [main] without proper controls
