If the `WORDPRESS_DB_NAME` specified does not already exist on the given MySQL server, it will be created automatically upon startup of the `%%REPO%%` container, provided that the `WORDPRESS_DB_USER` specified has the necessary permissions to create it.

+As an alternative to passing the database password via environment variables, `WORDPRESS_DB_PASSWORD_FILE` may be used instead of `WORDPRESS_DB_PASSWORD`, causing the initialization script to load the password from a file present in the container. In particular, this can be used to load passwords from Docker secrets stored in `/run/secrets/<secret_name>` files. For example:
|
|
|
+
|
|
|
+```console
|
|
|
+$ docker run --name some-%%REPO%% -e WORDPRESS_DB_PASSWORD_FILE=/run/secrets/db_password -d %%REPO%%
|
|
|
+```

If you'd like to be able to access the instance from the host without the container's IP, standard port mappings can be used:

|
|
```console
