Docker Architecture Explained: Client, Daemon & Engine (Deep Dive)
In Day 22 of our CKS Series we go back to the absolute core of modern infrastructure:
Docker. Many engineers use Docker commands, but do you actually understand the Architecture? Do you know why a Container is faster than a Virtual Machine?
Today, we break down the Docker Engine, the difference between Images and Containers, and why the industry moved from VMs to Containerization.
In this video, we cover:
✅ Docker vs. Virtual Machines: The resource war (RAM/CPU).
✅ The Architecture: Docker Client, Docker Daemon (dockerd), and the Registry.
✅ Key Concepts: Images, Containers, and Dockerfiles explained.
✅ Container Runtimes: Brief look at CRI-O, rkt, and runc.
✅ Basic Commands: How docker pull actually works under the hood.& Podman
If you are confused about how Docker binds to the OS kernel compared to a Hypervisor, this video is for you.
