"Can't connect to MySQL server on 'mysql' ([Errno 111] Connection refused)"

[levietanh0001]

Hello I saw your tutorial on medium and it worked great except for the database setup:

sqlalchemy.exc.OperationalError: (pymysql.err.OperationalError) (2003, "Can't connect to MySQL server on 'mysql' ([Errno 111] Connection refused)")

I got this issue when building and running the docker "loader" container, and because of this the api returns nothing on the /records/ endpoint.

Could you see if something was wrong? Thank you!
