Covers workflow structure, caching strategies, deployment automation, and cross-platform pipeline patterns. ## Core principles 1. Pipeline as code — version-controlled, reproducible, reviewable 2. Fast feedback — fail fast with parallel jobs and test splitting 3. Immutable artifacts — build once, deploy many 4. Secret hygiene — OIDC federation over static secrets 5. Progressive delivery — automated gates between environments ## References available - `references/github-actions-patterns.md` — Reusable workflows, matrix builds, caching, OIDC secrets, composite actions - `references/gitlab-ci-patterns.md` — DAG pipelines, includes/extends, environments, review apps, auto DevOps - `references/pipeline-optimization.md` — Parallel jobs, test splitting, artifact caching, incremental builds, build matrix - `references/deployment-strategies.md` — Blue-green, canary, rolling for k8s, Vercel, AWS ECS ## Scripts available - `scripts/detect-ci.sh` — Detects CI platform from project files (.github/workflows, .gitlab-ci.yml, Jenkinsfile, etc.) ## Assets available - `assets/github-actions-template.yaml` — Lint, test, build, deploy workflow template - `assets/gitlab-ci-template.yaml` — Equivalent pipeline for GitLab CI --- > Converted and distributed by [TomeVault](https://tomevault.io/claim/rnavarych) — claim your Tome and manage your conversions.
