I don't know if docker-compose file is not reading .sh file or not nor do I know somethings wrong on docker-compose file. can anybody help me with the configuration.
You have a connection issue as your web service cannot connect with your database.
Keep in mind that the hostname of your database equals the service name. So instead of connecting with 127.0.0.1:3306
connect with http://db:3306
instead.
I figured it out
