This is an optional variable. Set to `yes` to allow the container to be started with a blank password for the root user. *NOTE*: Setting this variable to `yes` is not recommended unless you really know what you are doing, since this will leave your MySQL instance completely unprotected, allowing anyone to gain complete superuser access.
# Initializing a fresh instance
When a container is started for the first time, a new database `mysql` will be initialized with the provided configuration variables. Furthermore, it will execute `.sh`- and `.sql`-files that are found in `/docker-entrypoint-initdb.d`. You can easily populate your %%REPO%% services by [mounting a SQL dump into that directory](https://docs.docker.com/userguide/dockervolumes/#mount-a-host-file-as-a-data-volume) and provide [custom images](https://docs.docker.com/reference/builder/) with contributed data.
