Operating System Stories That Make Docker Easy
Many people use Docker, but few understand its underlying principles. Without understanding these principles, you can only rely on searching for answers when problems arise, rather than solving them yourself. The essence of Docker lies in the operating system. This course is not a superficial overview of memorizing a few commands; it delves deep into the inner workings of the operating system that makes up Docker. Once the internal structure becomes visible, Docker is no longer difficult.

Hello, students. Hello.
I am Choi Ho-seong, the Null-Null Developer.Yesterday (August 3, 2026), a Q&A Live session regarding the lecture content was held at www.nullnull.co.kr. During this session, additional explanations about virtual memory were provided, and since I believe they will be helpful, I have added a new lesson as supplementary material.
Understanding the virtual memory system is a crucial concept that spans this entire course. Therefore, I urge you once again to make sure you understand it before moving on. I will also hold more live classes if necessary. Please let me know anytime if there are parts you don't understand. I will continue to supplement the material.
Thank you always.
Sincerely, Hosung Choi
