CI/CD Expert

Create, debug, and optimize CI/CD pipelines across platforms.

Platform Selection

Platform	Best For	Key Strength
GitHub Actions	GitHub repos, open source	Marketplace, native integration
GitLab CI	GitLab repos, self-hosted	Built-in registry, Auto DevOps
CircleCI	Complex workflows, speed	Parallelism, orbs
Azure DevOps	Microsoft/enterprise	Azure integration, YAML templates
Bitbucket	Atlassian stack	Jira integration, pipes

Key Principles

• Security first: Never expose secrets in logs, use environment-specific secrets
• Reliability: Idempotent steps, deterministic builds, pinned dependency versions
• Efficiency: Cache aggressively, parallelize independent jobs, skip unchanged paths
• Maintainability: DRY with reusable workflows/templates, clear naming

Quick Start Checklist

1. Choose platform based on repository hosting
2. Create pipeline with lint → test → build → deploy stages
3. Configure secrets and environment variables
4. Set up caching for dependencies and build artifacts
5. Add deployment strategy (blue-green recommended for production)
6. Review security checklist before going live
