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