[Reasons for Choosing This Course] - I chose this Docker course because it's short, compact, and the price is reasonable. [Course Strengths] - It was great that it didn't ramble and explained only the necessary parts in a structured way. - I usually have a hard time concentrating when taking online courses, but this one made it easy to focus. - It was convenient to study because the course materials were provided separately as PDF files and GitHub source code. [Study Method] 1. Because the course is short, I first listened to it all the way through to grasp the flow. 2. Immediately challenged myself with hands-on practice! 3. Re-watched the video when stuck. 4. Organized parts that were different from the lecture or that I was curious about separately. [Thoughts] - When I first encountered Docker, it felt so foreign that I thought, "What is this?" but it seems like the beginning was the most difficult. - At first, I just went along with it, learning terms like container, image, volume, and entrypoint, but as I continued to practice, I naturally memorized the Docker commands. - Concepts like multi-stage builds are still a bit difficult. - It feels like the more I learn, the more there is to study. I believe I will become more familiar with it as I work with it in practice! - I plan to improve the project deployment method based on what I've learned.
