Mount the sqldump file in docker as volume,
e.g.: ./dump.sql:/dump.sql

lonewanderer@debian:~docker exec -it [container_id] bin/bash

In the container run:

Enter your password.

Create a database via CREATE DATABASE db_name;

Switch to the new db: USE db_name;

Import the sql file: source /dump.sql
