🎬 Behind the Scenes of Kubernetes 🎬 You type one command and BOOM 🤯 – Kubernetes goes to work! 🚀 But what REALLY happens when you create a deployment? Imagine Kubernetes as a movie set 🎥 Here’s what goes on backstage when you run: "kubectl create deployment nginx-pods --image=nginx --replicas=3" 🌐 API Server (The Director) – orchestrating the entire show, ensuring everything is in place. 🎬 🗂️ etcd (The Script Supervisor) – keeping track of every change, ensuring your cluster's state is always known. 📝 🎯 Scheduler (The Casting Director) – finding the perfect actors (nodes) for your pods, matching resources and availability. 🎯 🤖 Controller Manager (The Continuity Expert) – ensuring your pods are always up and running as intended. 📈 📦 Nodes (The Actors) – bringing your containers (your app!) to life. With some help from CRI, CNI, and CSI for performance, networking, and storage. 🎭 🐳 Container Runtime (The Production Assistant) – Pull your app image (nginx) from Docker Hub and prepare it to perform. 🎥 Kubernetes is a blockbuster in automation – making sure your apps are always on the stage, ready to shine! 🌟 Check out this diagram for the full backstage view! 👇 #Kubernetes #CloudNative #DevOps #BehindTheScenes #K8sExplained #TechTheater

📚 Regretfully, I had to put my DevOps visual book project on hold. 🙏 I realized I need more experience to deliver the quality you deserve. But, I'm committed to learning and growing, so I can help you all better in the future! thank you for your understanding!

I'm working on writing a book! I'll release it by the end of July. You'll understand almost everything you need to know about Docker. I'll explain it with over 100 diagrams, and everything will be free!

Once you find your why, you don't need any external motivation to do what you're doing. Find your why.

BPF was originally designed for packet filtering, but it has evolved into a versatile framework that can be used for a wide range of purposes. With the introduction of eBPF, it has become even more powerful and flexible. Let's dive into the topic 🧵👇
