Introduction Kubernetes is powerful, but what’s the brain behind all those kubectl commands? That role is played by the kube-apiserver — the front door to your Kubernetes cluster. Everything goes through it: creating pods, scaling deployments, checking health — you name it. Let’s break it down in a way that’s easy to understand. What is kube-apiserver? kube-apiserver is the central communication hub of Kubernetes. It exposes the Kubernetes API and handles: ...

Introduction One of the magical things about Kubernetes is that it just knows how to restart pods, create replicas, or handle node failures. But how? Behind the scenes, there’s a key component called kube-controller-manager. Let’s demystify what it does — and why it’s essential. What is kube-controller-manager? It’s a Kubernetes control plane component that runs multiple controllers — small control loops that handle routine tasks. Think of it like an army of little workers keeping your cluster healthy and aligned with your YAML definitions. ...

Introduction If you’re just getting started with Kubernetes, its architecture can feel a bit overwhelming. Let’s break it down into understandable pieces. Kubernetes is like a well-organized team — and each component has a specific role. Control Plane vs Node Components Kubernetes is divided into two major layers: Control Plane – the brain of the cluster, makes decisions. Node Components – the workers, run the actual workloads. 🧠 Control Plane Components 1. API Server (kube-apiserver) The API server is the front door to your cluster. Everything — kubectl, dashboards, even internal components — talks to the cluster via this API. ...

Introduction Have you ever wondered how Kubernetes decides where to run your pods? That’s where the kube-scheduler comes into play. It’s one of the most important — yet often overlooked — components in the Kubernetes control plane. Let’s explore how it works in plain English. What is kube-scheduler? kube-scheduler is the default scheduler for Kubernetes. Its job is simple but critical: 🧠 It picks a node for every pod that doesn’t yet have a node assigned. ...

Amazon Web Services vs Cloudflare: What’s the Difference? Amazon Web Services (AWS) and Cloudflare are both major cloud providers, but they serve different purposes. AWS offers a full suite of cloud computing services, while Cloudflare focuses on performance and security at the network edge.
