At that time, my full project code was not available, and in this article, I provided only a basic introductory example, not a fully tested one. I have a question for you: Did you try running the project step by step first, or did you directly create a Dockerfile? I strongly suggest running the project manually, executing commands one by one, debugging any issues, and then creating and running the container. This will help you identify and resolve errors more effectively. Let me know if you need any help!
