Introduction1:44
Discover how Docker works, learn to run containers, build images, and use networking with Docker Compose and a private registry, then explore Docker Swarm and Kubernetes through browser-based labs.
Why Docker3:19
Docker packages each component—node.js, MongoDB, Redis, and Ansible—into its own container on a single VM, solving the matrix from hell by ensuring end-to-end compatibility across OS, libraries, and dependencies.
What are Containers?1:34
How Docker Works2:37
Learn how Docker containers share the Linux kernel to run various Linux-based distros on a single host, and how Docker packages applications to run anywhere without true virtualization.
Containers vs VMs2:16
Contrast virtual machines and Docker containers: containers share the host OS and libraries for lightweight, fast boot, while VMs run separate OSs with heavier overhead and full isolation.
Images and Registries1:45
Docker and Devops1:12
Getting started with Docker3:04
A note on installing Docker0:26
Demo - Setup and Install Docker4:06
Install Docker Engine on an Ubuntu Linux VM, verify prerequisites, install via the apt repository, start Docker, and run the Hello World image to confirm.
A Quick Reminder1:10
Focus on the course labs and videos to gain the necessary knowledge and skills, avoiding premature local setups until the course provides the right resources.
Resources
Student Preferences0:22

Basic Docker Commands7:08
Demo - Docker Commands Part - 13:16
Explore docker basics by running your first container, pulling images from Docker Hub, and using Alpine and Nginx to understand base images, web servers, and container workflows.
Demo - Docker Commands Part - 22:46
Demo - Docker Commands Part - 32:56
Explore docker image and container management by listing images, freeing space with docker rmi after removing containers using an image, and cleaning up with docker system prune.
Demo - Accessing labs2:14
Course setup0:23
Labs - Basic Docker Commands0:01

Image Tags2:15
Interactive Mode2:23
Learn how Docker handles input and terminals with interactive mode (-i) and pseudo terminal (-t). Use -i, -t, or -it strategically for prompts, piping data, and colored output inside containers.
Port Mapping1:59
Master port mapping in Docker by exposing container ports to the Docker host, enabling access via the host IP on mapped ports and supporting multiple apps on distinct ports.
Volumes and Bind Mounts1:41
Persist data in Docker by mapping the host directory /opt/data to /var/lib/mysql, so data survives container removal; use -v or --mount, with the latter clarifying the mount type.
Inspect and Logs0:51
Labs - Docker Run Commands0:01

Docker Images5:19
Learn to create your own docker image for a Flask web app, using a Dockerfile, base Ubuntu, environment variables, and entry point, with layered caching and pushing to Docker Hub.
Demo - Creating a new Docker Image5:15
Problems With Traditional Docker Builds6:05
Identify four problems with the traditional docker builder—re-downloading packages, secrets leaking in image metadata, architecture lock-in, and sequential stages—and anticipate how docker fixes them.
Modern Builds With Buildkit5:40
Docker Init3:40
Labs - Docker Images0:01
Command vs Entrypoint5:12
Labs - Command vs Entrypoint0:01
Environment Variables1:40
Configure a dockerized Python app with environment variables. Use docker run -e to set colors and docker inspect to view container environment variables for different containers.
Labs - Environment Variables0:01

Docker Engine3:52
Learn how the Docker engine runs applications in isolated containers through the daemon, REST API, and CLI, with three handoffs to container D and run C implementing the OCI runtime.
Namespaces2:19
cgroups0:55
Docker Storage8:54
Learn how docker stores data on the local file system under /var/lib/docker with image and container layers, writable layers, and volumes, using copy-on-write and mounts.
Labs - Docker Storage0:01

Container Orchestration3:21
Explore container orchestration as a solution to run containers across multiple hosts in production. Learn how it enables health checks, scaling, load balancing, and shared storage.
Docker Swarm3:20
Learn Docker Swarm basics, forming a multi-host cluster with a manager and workers, initializing with swarm init, joining workers, and using Docker service to deploy replicas across nodes.
Kubernetes Introduction6:18

Requirements

Basic System Administrator Skills
Good to have (Not Mandatory) access to a Linux System to setup Docker to follow along

Description

Docker is an open platform for developers and sysadmins to build, ship, and run distributed applications, whether on laptops, data center VMs, or the cloud.

This course introduces Docker to an Absolute Beginner using really simple and easy-to-understand lectures. Lectures are followed by demos showing how to set up and get started with Docker. The coding exercises that accompany this course will help you practice Docker commands, develop your own images using Dockerfiles, and practice Docker Compose. You will be developing Docker files for different use cases right in your browser. This way, you don’t really need to have your own environment set up to get some hands-on practice. The coding exercises will validate your commands and Dockerfiles and ensure you have written them correctly.

And finally, we have assignments to put your skills to the test. You will be given the challenge to solve using the skills you gained during this course. This is a great way to gain real-life project experience and work with the other students in the community to develop a Dockerfile and get feedback for your work. The assignment will push you to research and develop your own Docker images.

Our tools, courses, and resources will help you improve your Docker skills and help you gain a true understanding of the program.
