Docker CLI Deep Dive | Docker Images, Containers & Registry Explained (Hands-on Lab) | Hindi

In this chapter 2.2, we take a deep dive into Docker CLI commands and understand how to manage Docker images, containers, and Docker Registry using real hands-on examples.

We start from a clean environment and gradually explore how Docker works behind the scenes—
from pulling images to running containers, inspecting logs, executing commands, and even building our first custom Docker image.

🔍 Topics covered in this lecture:

✅ docker images – list local images
✅ docker ps & docker ps -a – view running and stopped containers
✅ docker pull – pulling images from Docker Registry (Docker Hub)
✅ docker run – short-lived vs long-running containers
✅ Ubuntu vs Nginx container behavior
✅ Images vs Containers (create vs start)
✅ docker start – reusing existing containers
✅ docker stop & docker rm – stopping and cleaning containers
✅ Filtering containers using docker ps --filter
✅ Stopping all containers using command chaining
✅ docker logs & docker logs -f – container logs
✅ docker exec -it – accessing running containers
✅ docker build – building your first Docker image
✅ Understanding Docker Registry & image caching

🧠 Key Concepts You’ll Understand

Why some containers exit immediately
Difference between short-lived and long-running containers
How Docker reuses cached images
How Docker Registry works behind the scenes
Best practices for container cleanup

🎯 Don’t worry if everything doesn’t feel clear yet — we’ll revisit these commands multiple times throughout the course with labs and assessments.
