Introduction Kubernetes has become the de‑facto platform for running containerized workloads at scale. While most developers interact with the API server, pods, and services daily, the underlying networking layer remains a black box for many. Yet, a solid grasp of how Kubernetes networking works internally is essential for backend engineers who need to: Diagnose connectivity issues quickly. Design resilient multi‑tier applications. Implement secure network policies. Choose the right CNI plugin for their workload characteristics. This guide dives deep into the internals of Kubernetes networking, covering everything from the Linux network namespace that isolates each pod to the sophisticated routing performed by kube-proxy. Along the way, you’ll find practical code snippets, YAML examples, and real‑world context that you can apply to production clusters today. ...
Introduction In modern web architecture, the term reverse proxy appears in almost every conversation about scalability, security, and reliability. While a forward proxy sits between clients and the internet, a reverse proxy sits in front of one or more servers, acting as an intermediary for inbound traffic. It receives client requests, applies a set of policies, and forwards those requests to the appropriate backend service. The response then travels back through the same proxy, allowing the proxy to perform transformations, caching, authentication, and more before delivering the final payload to the client. ...

One of the more nuanced features is Git submodules, a mechanism that lets one repository (the super‑project) embed another Git repository at a specific directory path. Submodules have been around since Git 1.5, but they remain a source of confusion, frustration, and, when used correctly, powerful modularity. ...
