Need to extend import file size of database in mysql that is running on docker

Question

I want to import 14 GB database file in mysql:5.7 which is running on Docker. But couldn't import the large database.

I have tried to add the max upload size with 16GB in docker-compose.yml file, but when I go to import, it shows request entity is too large.

Now I want to expect to you to give me guideline to extend the max upload file size.
