Since you take a mysql dump, automatically the .sql file will appear in your host folder. Tell me what you think?

@ambrosiora

Thanks! I already solved its (inside my script) this way:

docker cp <container_id>:/file/path/within/container /host/path/target

Thank you so much. Restore command worked like a charm. Unbelieveable to see that instructions on official Docker image page fail.
