In you Dockerfile you must have a shared folder. Shared folder is a directory in your host machine that is mounted to Docker instance.
Put the exported sql file in the shared folder.
Login to your Docker instance via docker exec -it DOCKER_CONTAINER_ID bin/bash
.
Login to MySQL via mysql -u USERNAME -p
.
