Readme logging into mysql container

[pavelloz]

I think readme is not correct when it comes to logging into mysql container.

I have to do docker ps and get sha of running container to get inside the container, the label doesnt work for some reason.
Neither mysql or mysqldb did not work.

docker-nginx-php-mysql|master⚡ ⇒ docker exec -it mysql bash

Error: No such container: mysql
