DevOps Skill

Implement CI/CD pipelines, infrastructure automation, and DevOps workflows.

When to Use

Use this skill when the user wants to:

• Create CI/CD pipelines
• Configure automation scripts
• Set up infrastructure as code
• Implement deployment workflows
• Work with GitOps practices
• Configure build and deployment tools
• Set up release management

CI/CD Tools

Pipeline Orchestration

• GitHub Actions: Git-based workflows
• GitLab CI/CD: GitLab integrated
• Jenkins: Classic CI server
• CircleCI: Cloud-based pipelines

Infrastructure as Code

• Terraform: Multi-provider IaC
• Ansible: Configuration management
• Puppet: Configuration management
• Chef: Configuration management

GitOps

• ArgoCD: GitOps controller
• Flux: GitOps toolkit
• Sealed Secrets: Git-based secrets

Pipeline Stages

1. Build: Compile, package, test
2. Test: Unit, integration, E2E tests
3. Deploy: Staging, production
4. Verify: Smoke tests, monitoring
5. Rollback: Automatic rollback on failure

Common Patterns

Monorepo vs Multirepo

• Monorepo: Single repo, shared tooling
• Multirepo: Separate repos, independent releases

Build Artifacts

• Docker images
• S3 artifacts
• Registry storage
• Version tagging

Deployment Strategies

• Blue-green deployment
• Canary release
• Rolling update
• Shadow deployment

Best Practices

• Pipeline as code: All in version control
• Idempotent actions: Safe to run multiple times
• Caching: Speed up builds with caches
• Parallel steps: Run independent tasks in parallel
• Visibility: Pipeline logs and status
• Security: Scan for vulnerabilities, secrets management

Deliverables

• Pipeline configuration
• CI/CD scripts
• Documentation
• Rollback procedures
• Monitoring integration

Quality Checklist

• Pipelines are automated and reliable
• Tests are run in pipeline
• Artifacts are versioned
• Rollback is possible
• Security scanning included
• Documentation is updated
• Pipeline is reusable
