What you can get from this lecture is a decent understanding of Docker and Docker Compose. However, I think it was a little lacking to solve the individual practice perfectly by using the knowledge learned through the lecture on my own. In addition, I would like a little more detailed explanation. Things like the options used in docker-compose, or simple diagrams such as which part of docker-compose.yml is connected through which port. The concept was vague in my head and not clearly grasped, but I think the concept became a little clearer through this lecture. Thank you.
