Docker Architecture

Client-Server Model

💡 Docker, ki, ARCHITECTURE, EK, RESTAURANT, jaisi, hai — TUM, (Docker, CLI, CLIENT) WAITER, ko, ORDER, dete, ho, WAITER, KITCHEN, (Docker, DAEMON) tak, ORDER, PAHUNCHATA, hai, aur, KITCHEN, INGREDIENTS, (IMAGES) STORE-ROOM, (REGISTRY) se, MANGWATI, hai.

Docker, EK, CLIENT-SERVER, ARCHITECTURE, follow, karta hai. Docker, CLIENT, (CLI, jisse, tum, "docker run" jaisi, commands, type, karte, ho) REST, API, ke, zariye, Docker, DAEMON, (dockerd) se, BAAT, karta hai.

Docker, DAEMON, HI, ASLI, KAAM, karta hai — IMAGES, BUILD, karna, CONTAINERS, RUN, karna, NETWORKS, aur, VOLUMES, MANAGE, karna. Daemon, images, ko, DOCKER, HUB, jaise, REGISTRY, se, PULL, karta hai, JAB, WO, LOCALLY, available, nahi, hote.

# Client -> Daemon -> Registry, ye poora flow hai
docker pull nginx        # Daemon, registry se image pull karta hai
docker run nginx         # Daemon, image se container start karta hai
docker ps                # Client, daemon se running containers ki list mangta hai
