# CI/CD Pipeline
|
|
|
|
## Definition
|
|
CI/CD (Continuous Integration/Continuous Delivery/Deployment) pipelines automate the process of building, testing, and deploying software changes.
|
|
|
|
## Components
|
|
|
|
### Continuous Integration (CI)
|
|
- Automated builds on code commits
|
|
- Automated testing (unit, integration, e2e)
|
|
- Code quality checks and linting
|
|
- Artifact generation
|
|
|
|
### Continuous Delivery (CD)
|
|
- Automated deployment to staging environments
|
|
- Manual approval gates for production
|
|
- Configuration management
|
|
|
|
### Continuous Deployment
|
|
- Fully automated deployment to production
|
|
- Feature flags for gradual rollout
|
|
- Automated rollback capabilities
|
|
|
|
## Tools
|
|
- **CI/CD Platforms**: Jenkins, GitLab CI, GitHub Actions, CircleCI, ArgoCD
|
|
- **Build Tools**: Maven, Gradle, npm, Docker
|
|
- **Testing**: JUnit, PyTest, Selenium, Playwright
|
|
|
|
## Best Practices
|
|
1. Keep the pipeline fast (under 10 minutes)
|
|
2. Fail fast — run fastest tests first
|
|
3. Use meaningful commit messages and branch names
|
|
4. Implement proper caching strategies
|
|
5. Store build artifacts securely
|
|
6. Enable parallel test execution
|
|
|
|
## CI/CD Pipeline Across DevOps Maturity Levels
|
|
|
|
| Maturity | Pipeline Maturity |
|
|
|----------|------------------|
|
|
| Phase 1 | No CI/CD — manual builds, manual testing, milestone-based releases |
|
|
| Phase 2 | Basic version control, some automation for risk reduction, unit/integration/E2E tests |
|
|
| Phase 3 | Automated infrastructure provisioning, security scans in CI, more frequent deployments |
|
|
| Phase 4 | Continuous integration pipeline, immutable infrastructure managed through pipelines, performance testing |
|
|
| Phase 5 | Zero human intervention, real-time data-driven decisions, multiple daily deployments |
