Docker explained in 2 minutes! Most developers use Docker daily without understanding what happens under the hood. Here's everything you need to know. Docker has 3 main components: 1️⃣ Docker Client: Where you type commands that talk to the Docker daemon via API. 2️⃣ Docker Host: The daemon runs here, handling all the heavy lifting (building images, running containers, and managing resources) 3️⃣ Docker Registry: Stores Docker images. Docker Hub is public, but companies run private registries. Here's what happens when you run "docker run": • Docker pulls the image from the registry (if not available locally) • Docker creates a new container from that image • Docker allocates a read-write filesystem to the container • Docker creates a network interface to connect the container • Docker starts the container That's it. The client, host, and registry can live on different machines. This is why Docker scales so well. Understanding this architecture makes debugging container issues much easier. You'll know exactly where to look when something breaks. ____ If you found it insightful, reshare with your network.
