First Docker Fundamentals Course ─ Learn the Complete Picture of Environment Setup from Concepts to Practice

In application development, "being able to quickly and accurately reproduce the development environment" is extremely important. One effective means for achieving this is Docker. This video explains everything from Docker's basic concepts and ideas to the actual process of building and running applications using only Docker. You'll also learn the basics of docker-compose, which allows you to manage multiple containers together, giving you a better understanding of environment setup that's closer to real-world practice.

Mr. Klein's course, both the previous AWS one and this current one, uses whiteboard explanations that feel very Japanese-style, which I really appreciated. This one course is sufficient to learn the basics of Docker!

I'm a complete beginner who doesn't know what Docker is, but I think this is a course that makes it easy to understand in one go! The practical parts are explained in an easy-to-understand way, so it's easy to follow along while watching. I'd like to take the remaining courses too~

What you will gain after the course

  • What is Docker and why is it necessary?

  • Basic structure of Dockerfile and main commands (FROM, RUN, COPY, CMD, etc.)

  • How to create and start containers with Docker

  • Commonly Used Docker Commands

  • How to start multiple containers (API server + DB) using docker-compose

  • Practical Docker Operation Tips for Real-World Use (Multi-stage Builds, Unnecessary Resource Cleanup, Cloud Services)

どこでも、同じ環境を一瞬で。

アプリケーション開発において、「開発環境を素早く、正確に再現できること」は非常に重要です。  

そのための有効な手段の一つが Docker です。

この動画では、Docker の基礎から実践的な環境構築までを解説し、docker-compose による複数コンテナ管理も学べるため実務に直結するスキルを効率的に習得できます。

ここでご紹介する内容は、現代的な開発環境で広く役立つDocker活用の基礎です。  
学んだ知識は様々な環境で応用でき、環境構築の効率や再現性の向上に役立ちます。


あくまで基礎の理解にフォーカスしているため詳細な設定や特殊なケースの解説は含まれませんが、今後の応用に向けた土台を築くことを目的としています。

🎥動画の特徴

#1.ホワイトボードを用いてDockerの概念を視覚的に解説し、初めての方でも理解しやすい構成


#2. 概念理解に加え、実際にPC上でアプリを構築・実行するデモを収録

#3. 「なぜこの設定が必要なのか」という背景まで説明し、設定の意味を理解できる

#4. 実務で利用されるNode.js + Express + TypeScriptを例に、汎用性の高い学びを提供

I hope to use my slightly-above-average IT knowledge to explain things in my own easy-to-understand way, so that people can develop even a small interest in programming and IT.

I hope to share my slightly-above-average IT knowledge in an easy-to-understand way to help spark even a little interest in programming and IT.

In my videos, I provide explanations for those who find these topics difficult, with the message that "it may look hard, but it's actually simple."


Rather than simply following operations and procedures, I strive to delve into the reasons and significance, such as "why we do it," so that you can understand the essential knowledge.

By incorporating diagrams and actual operation demos, while also sharing my own personal experiences,

My goal is to provide the kind of support that allows everyone to take their first steps into the world of IT with confidence.


I hope that through IT knowledge, I can help enrich your lives even just a little bit.


Hello, I'm KLeIn.

I want to share the IT knowledge I have gained with beginners in my own easy-to-understand way, so that you can develop even a small interest in programming and IT.

In my lectures, I explain things with the mindset that "it may look difficult, but it's actually simple" for those who feel that IT is "hard." Rather than just following operation methods or procedures,

My lectures are designed for those who feel that IT is "difficult," with the mindset of showing that "it may look hard, but it's actually simple." Rather than just following operations or procedures, I delve deep into the reasons and meanings behind "why things are done that way" to ensure you can understand the essential knowledge.

By incorporating visual explanations, live demonstrations, and my own personal experiences, I aim to help you take your first steps into the world of IT with confidence.

I hope that IT knowledge will enrich your life, even if only a little.
