1: History and Motivation
Examine the evolution of virtualization technologies from bare metal, virtual machines, and containers and the tradeoffs between them.
2: Technology Overview
Explores the three core Linux features that enable containers to function (cgroups, namespaces, and union filesystems), as well as the architecture of the Docker components.
3: Installation and Set Up
Install and configure Docker Desktop
4: Using 3rd Party Container Images
Use publicly available container images in your developer workflows and learn how about container data persistence.
5: Example Web Application
Building out a realistic microservice application to containerize.
6: Building Container Images
Write and optimize Dockerfiles and build container images for the components of the example web app.
7: Container Registries
Use container registries such as Dockerhub to share and distribute container images.
8: Running Containers
Use Docker and Docker Compose to run the containerized application from Module 5.
9: Container Security
Learn best practices for container image and container runtime security.
10: Interacting with Docker Objects
Explore how to use Docker to interact with containers, container images, volumes, and networks.
11: Development Workflow
Add tooling and configuration to enable improved developer experience when working with containers.
•Developer Experience Wishlist
12: Deploying Containers
Deploy containerized applications to production using a variety of approaches.
Course Overview
Welcome to the Docker and Containers: Beginner to Pro course by DevOps Directive!
This course is designed for beginner through intermediate software engineers who have familiarity with web applications and some basic linux shell commands.

Part 1 (Modules 1-4)
In the first part of the course we will cover:
- What Docker and Containers are
- Why they exist
- The underlying technologies
- How to set up Docker Desktop
- How to persist data when working with containers
- How to use 3rd party container images
Part 2 (Modules 5-12)
In the second part of the course, we will build on that foundation to:
- Build a sample 3 tier web application using React, NodeJS, Golang, and PostgreSQL
- Create and optimize Dockerfiles to build containers images for our applications
- Use container registries to store and share our container images
- Run our application with docker and docker compose
- Secure our container image and containers at runtime
- Interact with Docker images, containers, volumes, and networks
- Learn to incorporate Docker into our development workflow with hot reloading, debugging, and testing
- Deploying containers to the cloud!
Prerequisites
While I do my best to explain things as simply as possible, it will be helpful if you have the following:
- Familiarity with web applications (the course examples are in JavaScript + Golang)
- Basic shell commands (enough to build/run an application in language of your choosing on Linux)
