📝 Description

Docker is used everywhere in modern software engineering, but what actually happens under the hood when you run a container?

In this video we break down how Docker works internally.

You'll learn:

• What Docker images really are
• How containers are created from images
• How Linux namespaces isolate processes
• How Cgroups control CPU and memory
• How Docker layers filesystems
• What actually happens when a container starts

Instead of a simple surface explanation, we dive into the real mechanics behind containers so you understand how Docker works internally.

This knowledge is essential if you want to understand modern DevOps tools like:

• Kubernetes
• containerd
• Podman
• CI/CD pipelines
• cloud deployments

By the end of this video you'll understand why Docker became the standard for containerization.
