I created this repository to keep my learning, notes, and code in one place for various tools in DevOps. Now, it's helping thousands of learners, practitioners, and professionals every day in their DevOps journey.
A personal learning journal for DevOps tooling that grew into a community resource. Covers Docker, Kubernetes, GitHub Actions, Helm, ArgoCD, Prometheus, Terraform, and more — organized as notes plus working code samples. Aimed at people learning DevOps from scratch or filling gaps in specific tools.
The working sample files are genuinely useful — the Kubernetes directory alone has deployment strategies (blue-green, canary, rolling), StatefulSets, RBAC, Gateway API, and PV examples with real manifests you can apply. The Go concepts section goes from basic syntax all the way to goroutines, channels, race conditions, and wait groups in numbered files, which is a practical learning path. It has a hosted Docusaurus site so you can read it as docs rather than browsing GitHub markdown. The repo is actively maintained (pushed April 2026) and structured well enough that adding new tool sections is straightforward.
Content quality varies heavily by section — Docker and Kubernetes are solid, but several sections are thin stubs with just an introduction.md and a learning-resources.md link dump. There are no tests anywhere, so you can't verify whether the scripts or sample apps still work. The Golang apps include compiled binaries checked into git (pizza-rating.exe, mux-api binary), which is sloppy and a red flag if you're cloning it for reference. It's one person's notes, so gaps in their own knowledge become gaps in the content — notably, there's no coverage of observability beyond Prometheus scraping basics, and the networking section is shallow.
