this is server.sh file:

python3 -m http.server $PORT

Solution 1: ash

So here is the thing. I think there are some problems with his code. As I tried to build with his code yesterday but things weren't working as they should be. I spend 2hours with his code of which 50% was spent on building the image but it was never completed. No problem I tried to modify some things and I am sharing some code with you on GitHub https://github.com/ash-0001/fludino.git. Just keep learning and sharing. Good Is Image.

You have to use two commands to initialize this: Before that move into the directory with your cmd

  1. docker build -t flut .
  2. docker run -i -p 808:4040 -td flut
