Practical articles on AI, DevOps, Cloud, Linux, and infrastructure engineering.
Your pipeline holds the keys to production and signs off on everything you ship, so harden both the pipeline itself and the artifacts it builds.
Stop stashing long-lived AWS access keys in GitHub secrets and let OIDC hand your workflows short-lived, scoped credentials instead.
Most GitHub Actions pain comes from the same handful of jobs done wrong. This is the map: the recipes that make pipelines fast, secure, and cheap.
A prioritized toolkit for cutting CI time: measure the critical path first, then cache, parallelize, run only what changed, and shrink the work itself.
Run only the CI jobs a change actually affects using if conditionals, trigger path filters, and per-job path detection in a monorepo.
A practical guide to matrix builds in GitHub Actions that tests across versions and platforms without burning your monthly minutes.
A practical guide to building, tagging, caching, and pushing Docker images from GitHub Actions using buildx, GHCR, and multi-arch builds.
Stop re-downloading the same packages on every CI run by caching dependencies with keys that actually hit.
A practical guide to scoping GitHub Actions secrets correctly, avoiding leaks in logs, blocking fork-PR theft, and preferring OIDC over stored keys.
A production-focused Argo CD and GitOps guide: declarative Applications and ApplicationSets, app-of-apps, sync waves and hooks, automated self-heal and prune, progressive delivery with Argo Rollouts, projects/RBAC, and secure secrets — with copy-paste examples.
A production-focused CircleCI guide: orbs, reusable commands and executors, workflows with fan-in/fan-out, contexts and OIDC for secrets, layered caching, test splitting, approval jobs, and dynamic config — with copy-paste examples.
Every CI/CD platform claims to be fast and easy. The real differences are in pricing, self-hosting, and where each one falls apart at scale. This is the map.
