## Overview

This repository is a collection of hands-on engineering and DevOps walkthroughs, not one integrated application. Its examples cover Kubernetes, containers, monitoring, logging, service meshes, messaging, and language-specific development. The clearest end-to-end runtime flow in the sampled code is the traced playlists API, which loads playlist data from Redis and fetches each referenced video from a videos API. Other samples are independent demonstrations. Some documented capabilities have no sampled implementation, so their wiring is intentionally not inferred.

Main entry points: [`tracing/applications-go/videos-api/app.go`](https://github.com/koonisetty/docker-development-youtube-series/blob/master/tracing/applications-go/videos-api/app.go) (Videos API), [`tracing/applications-go/playlists-api/app.go`](https://github.com/koonisetty/docker-development-youtube-series/blob/master/tracing/applications-go/playlists-api/app.go) (Playlists API), [`kubernetes/servicemesh/applications/playlists-api/app.go`](https://github.com/koonisetty/docker-development-youtube-series/blob/master/kubernetes/servicemesh/applications/playlists-api/app.go) (Playlists API), [`kubernetes`](https://github.com/koonisetty/docker-development-youtube-series/tree/master/kubernetes) (Kubernetes guides)
