Failed to dockerize a laravel app (Exit Code 1) - mysql

Question

I am new to Docker. This can be marked as duplicate but none of the other solution works. I am completely clueless. I have been stuck on this for 9 hours. Tried every possible solution to my knowledge from StackOverflow.
I am on Ubuntu 20.04 btw.
