J.PHIL teacher, I am a non-major developer who listened to [Mastering Big Data Pipeline] that you released before. ㅎㅎ I graduated from the business administration department and have been studying on my own through hardships~ It is not an easy path, so I have many concerns, but since it deals with practical things, I feel proud of studying this and that~~ If I had listened to it later, I would have come back to Docker a lot, but it was helpful to quickly and systematically organize the theory and practice like this with the "chicken price" ㅋㅋ~~ I will have to keep listening to it repeatedly for the remaining period. I vaguely thought it would be difficult, but I feel confident and proud. Thank you!!
