Description

Master Containers & Linux: Hands-On Course on Docker, Kubernetes, Namespaces, Overlay FS, and Cgroups

Requirements

• Basic programming skills.

• Basic familiarity with Linux, including text editors and simple commands.

• Curiosity and willingness to explore how container technologies work under the hood.

• Patience to follow along with concepts, demos, and hands-on exercises using the included Virtual Machine (VM).

Note: No prior knowledge of Docker, Kubernetes, or advanced Linux is required. All necessary concepts will be explained during the course.

Course Description

Take your Linux and container knowledge to the next level! This course offers a bottom-up approach to understanding containers, focusing on the core mechanisms that make them work—Namespaces, Overlay Filesystems, and Cgroups.

Unlike other courses that focus only on Dockerfiles or Kubernetes YAML files, this course dives deep into the fundamental technologies behind containerization, showing how applications are isolated and resource usage is controlled.

You will learn not only how to use containers but why they work, enabling you to master Docker, Kubernetes, and container orchestration with confidence.

Why This Course Is Different

• Deep Technical Understanding: Learn how Namespaces, Overlay FS, and Cgroups combine to create containerized environments.

• Hands-On Learning: Practice with a ready-to-use Ubuntu VM included with the course.

• Simple Examples: Clear, easy-to-understand demos instead of complex applications.

• Practical Application: Connect theory to real-world usage in Docker and Kubernetes.

What You Will Learn

1. Namespaces: The Foundation of Isolation

• Understand how namespaces provide application isolation.

• Explore different types of namespaces: PID, MNT, IPC, USER, and UTS.

• Hands-on exercises demonstrating each namespace.

2. Overlay Filesystems: Efficient File Sharing

• Learn the role of Overlay FS in container environments.

• Create and use overlay filesystems to share modules across containers.

• Demonstrate real examples to visualize filesystem layering.

3. Cgroups: Resource Management Made Simple

• Control CPU, memory, and other resources for applications.

• Create your own cgroups to limit resource usage in demo applications.

• Understand how cgroups integrate with Docker and Kubernetes.

4. Related Linux Concepts

• Proc filesystem, mount points, and other key Linux concepts.

• Gain foundational knowledge required to fully understand namespaces and cgroups.

5. Docker: Image Layering & Resource Control

• Understand Docker images, layers, and how overlay FS works under the hood.

• Learn how Docker uses cgroups to control CPU and memory allocation.

• Hands-on examples: Build images, explore layers, and manage container resources.

6. Kubernetes: Pods, ReplicaSets & Deployments

• Explore Pods and understand their purpose.

• Create Pods using namespaces and Kubernetes manifests.

• Learn about ReplicaSets, Deployments, and Control Plane components.

• See how cgroups manage resources within Pods.

How to Approach This Course

• Take Your Time: Don’t rush. Topics like mount namespaces and image layering require careful attention.

• Hands-On Practice: Follow along with examples and try your own experiments in the VM.

• Revisit and Reflect: Some concepts take time to fully understand—review demos, pause, and practice repeatedly.

• Build a Strong Foundation: Mastering these fundamentals makes learning advanced container technologies much easier.

---

Course Highlights

• Detailed hands-on exercises with a pre-configured Ubuntu VM.

• Clear explanation of core concepts such as Namespaces, Overlay FS, and Cgroups.

• Step-by-step Docker image and container exploration.

• Deep dive into Kubernetes Pods and Control Plane mechanics.

• Practical, real-world examples to solidify learning.

---

Key Takeaways

• Gain foundational knowledge of how containers and Kubernetes work.

• Understand the mechanisms behind isolation and resource control.

• Apply learning in real-world Docker and Kubernetes scenarios.

• Build the confidence to explore any container technology with clarity.
