It was good to be able to understand Docker in general and practice various commands. It was even better to be able to review with the PDF materials provided! The content itself is easy to understand because it is explained kindly and in an easy-to-understand manner! ㅎㅎ The only thing that was a little disappointing was that the answers for the individual practice part are provided as a txt file, so it would have been better if you had added a lecture so that I could practice and follow along personally! (Of course, it would have been difficult because it takes more time to produce it ㅠㅠ) + I also purchased the Kubernetes lecture, so I will watch it later and write a review ㅎㅎ Thank you~
