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.
