Best Docker Tutorial IMHO

While in the process of trying to learn Docker as part of my Software Architecture class, I watched 5 YouTube videos. YouTube has been a real benefit to me for learning college level science courses. I have had good luck with Biology, Organic Chemistry, and even Statistics tutorials, but have not had much luck so far with Computer Science videos. There are some good ones out there, though, and “Docker Tutorial for Beginners – A full DevOps course on how to run applications in containers [1] is certainly one the best I have seen.

This 2-hour course by Mumshad Mannambeth covers all the bases in a clear and interesting manner and is enhanced with well thought out structure and graphics. The lectures are accompanied by direct access to a full-fledged Docker environment through labs [2] on a website

The course is broken up into sections exploring the definitions of containers, images, Docker itself, why you need it, and what you can do with it. He then goes on to explain the basic commands needed to create a docker image, how to build and run it in a container, the basic concepts of Docker Compose, YAML, and DockerFile.

He leaves the technical details of installing Docker Desktop for Windows and the MAC until later in the video, giving more time up front to clearly describe why you want to use it, what it accomplishes for the software development community, and how containerization is the future of enterprise level software. These installation sections are also well done but are not relevant for those who already have docker installed, or for those without the time to build their own environments. The tutorial and accompanying interactive quizzes on the right side of the site, are resources I will come back to in the future, because of their depth and clarity.

He then allocates about 40 minutes going into docker concepts and commands in depth and follows up with a history and description of the importance of continuous integration using container orchestration tools like Swarm and Kubernetes. He clearly lays out the architecture of a system that is complex, distributed, fault-tolerant, and easy to implement. He details the importance of DevOps, where the design, development, testing, and operations teams are seamlessly connected and have a symbiotic relationship. This makes everyone’s jobs easier, cuts down on departmental finger pointing when things go wrong, and brings product to market much quicker and with less bugs shipped.

He also covers the following areas:

1. Layered architecture

2. Docker registry

3. Controlling volumes

4. Port forwarding

5. Viewing logs

6. The advantages of container architectures over Virtual Machines and Hypervisors.

7. KubeCtrl

I was pleasantly surprised to have found this. Maybe I should give the computer science YouTube community more credit.
