Assuming an existing database does not exist in the container's data directory already, it will create an empty database for you. The name of this database is controlled by the environment variable `MYSQL_DATABASE`. This defaults to 'myData'. If you would like to create a database called 'CompanyX', for example, you would set the environment variable as follows:

The entrypoint script of the container simply checks to see if the */var/lib/mysql* directory is empty and, if so, creates a new database for you. Thus, if you want to import an existing database, you simply have to mount a valid *mysql* subdirectory:
|
||||
|
||||
```bash
|
||||
docker run -d -v /existing/mysql:/var/lib/mysql docker.asifbacchus.app/mariadb/ab-mariadb-alpine

If you want to 'instantiate' your newly created database (add tables, some default data, set privileges, etc.) then you can import SQL files with commands preloaded. Any *.sql* or *.sql.gz* files mounted in the container's */docker-entrypoint-initdb.d* folder will be imported after the new database is created.
|
||||
|
||||
```bash

docker run -d -v /sql/import/scripts:/docker-entrypoint-initdb.d docker.asifbacchus.app/mariadb/ab-mariadb-alpine

You should review the logs when doing this to see if MariaDB throws any errors due to syntax errors or other mistakes in your SQL files. An easy way to do this is:

```bash

docker run -d --name db -v /sql/import/scripts:/docker-entrypoint-initdb.d docker.asifbacchus.app/mariadb/ab-mariadb-alpine && docker logs -f db

I hope this container is useful to you and helps you run a database where memory may be at a premium. I do my best to make sure everything runs properly and as much like the official container as possible. If you find any bugs, implementation issues or have any suggestions, please file an issue and let me know! I am *NOT* affiliated with MariaDB in any way and this container is strictly my implementation of their software. Please **do not** bother them with any issues you have with this container, let me know instead! Happy dockerizing :-)
