Practical articles on AI, DevOps, Cloud, Linux, and infrastructure engineering.
A practical guide to building, tagging, caching, and pushing Docker images from GitHub Actions using buildx, GHCR, and multi-arch builds.
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.
A production-focused Jenkins guide: declarative pipelines, shared libraries, ephemeral agents on Kubernetes, scoped credentials, parallel stages, input approvals, post-block rollback and notifications, and Configuration as Code — with copy-paste examples.
Woodpecker forked Drone when the license changed. Here's how the two compare for small teams and homelabs that just want simple container-native CI.
Buildkite runs the control plane and lets you own the compute; Actions keeps everything close to your repo. Here's how they actually differ once you scale.
Both run pipelines as CRDs inside your cluster, but they were built for different jobs. Here's how Tekton and Argo Workflows actually differ in practice.
Hosted runners bill by the minute, and that meter never stops. Here's the break-even math on running your own, plus the tradeoffs nobody warns you about.
GitHub Actions OIDC gets all the attention, but GitLab, Buildkite, and CircleCI issue the same signed tokens. Here's how to trust them without opening a hole.
A team was burning 40,000 CI minutes a month and could not say why. Here is how GitHub Actions billing actually works and where the money leaks.
A production-focused GitLab CI/CD guide: include/extends templates, rules and workflow, needs DAGs, cache vs artifacts, protected environments, masked/protected variables and Vault, built-in security scanning, and review apps — with copy-paste examples.
One bundles your whole toolchain, the other lets you build anything from parts. The right pick depends on how much glue you want to own.
