This is my first time leaving a review for Inflearn. (It may not be true.) I'm sorry to say this, but you are really amazing.. Docker is Docker, but you also teach me various theoretical bases, and thanks to you, I was able to re-confirm things that I was confused about or didn't remember well, so I'm having a great time with the lecture. But when I did the last practice in Section 5, a small error occurred when I launched the nginx container with a docker file. But what's the big deal about such a small thing in a lecture that contains such great meaning? I'll figure it out. Your voice is really nice, and I'm so grateful.... How did you distribute such an amazing lecture by clearly picking out only the necessary parts without explaining it in detail? I wonder if you made the lecture over 6 days and took a break on the 7th day? Or are you Docker itself? Is your MBTI Devops? I'll end my brief course review here, and I'll go listen to all the remaining lectures. I hope you stay healthy and become rich.
