Docker Architecture Explained | How Docker Client, Host & Registry Work | Hindi

In this chapter 1.3, we go one level deeper and look inside Docker to understand how it actually works.

Now that we know why containers exist and how they compare with virtual machines, it’s time to explore Docker Architecture and its key components.

In this video, you’ll learn:

What is Docker Architecture at a high level
The role of Docker Client and how Docker commands work
What happens inside the Docker Host
Understanding Docker Daemon (dockerd)
How containers and images are managed on the host
What is an Image Registry (Docker Hub, public & private registries)
How docker run, docker build, and docker push work internally
Image vs Container explained with a simple OOP analogy

We’ll also see how all Docker components interact with each other using REST APIs and how Docker makes application deployment simple, portable, and consistent.

This chapter gives you a strong foundation before moving into practical Docker commands and real-world examples in upcoming videos.

📌 Next videos will cover hands-on demos and deeper concepts step by step.
