Syllabus

Introduction to Docker

In this module, we will lay the groundwork for your Docker journey, introducing key concepts such as containerization and Docker's role in DevOps workflows. You will explore Docker's architecture, essential components, and tools, setting you up for hands-on experience with Docker's core functionality.

Getting Started with Docker

In this module, we will guide you through the process of installing and configuring Docker on multiple platforms. You’ll get hands-on experience with Docker's CLI, explore Docker Playground, and begin interacting with Docker commands. This section will prepare you for more advanced Docker tasks by ensuring you have a solid setup and understanding.

Docker Images

In this module, we will introduce Docker images as the fundamental building blocks for containers. You'll explore their lifecycle, manage them with Docker commands, and learn how to utilize Docker Hub for storing and sharing images. This section provides essential skills for working with Docker images effectively.

Docker Containers

In this module, we will dive into Docker containers, teaching you how they encapsulate applications and their dependencies. You’ll practice managing containers with Docker CLI, ensuring you’re ready to create, run, and troubleshoot containers effectively in real-world environments.

Building an Image with a Dockerfile

In this module, we will explore how to create custom Docker images from Dockerfiles. You’ll learn how to structure a Dockerfile, build images, troubleshoot common issues, and optimize your Dockerfiles. By the end of this section, you’ll be comfortable creating and running containers from your own Docker images.

Docker Networking

In this module, we will introduce Docker networking and teach you how containers communicate within their networks. You’ll explore the fundamentals of Docker networking, including the bridge and host networks, and practice managing networks with Docker CLI. This section prepares you to create custom networks for more complex applications.

Docker Volumes

In this module, we will focus on Docker volumes and their role in data persistence. You’ll learn how to manage volumes, mount them to containers, and ensure your data remains intact even when containers are restarted. This section is crucial for working with stateful applications in Docker.

Containerizing Applications (Sample Project Using Python)

In this module, we will take you through the process of containerizing a Python application using Docker. You’ll learn to build Dockerfiles, use multi-stage builds, and deploy your app to Docker Hub. This hands-on project will give you a practical understanding of the containerization process, preparing you to deploy your own applications.

Docker Compose

In this module, we will introduce Docker Compose, a tool for managing multi-container applications. You’ll learn how to define and configure applications in the Compose.yaml file, use Docker CLI to manage services, and deploy multi-container apps efficiently. This section will equip you with the tools to simplify complex Docker deployments.
