If you're planning to take this course for the first time in 2025, I would strongly advise against it... It's good for getting a very simple overview of what Docker is and how to use it. However, this course was released in 2021, and the problems that I couldn't solve in the Windows development environment when I first bought and took the course four years ago have now reached a point where current students have to search and share opinions to solve them. There are also many unresolved issues. (I don't know if it works well on Mac.) In addition, some features have become paid, and the version has changed a lot, so some features do not work properly in the latest version. I don't know how much this course costs now, but finding and taking a course that's closer to 2025 would be better for your mental health.
