Hey,
 when installing Koha I need it to use existing remote MariaDB database instance with defined access data, e.g.:

- database host: mydb
- database user: myuser
- database user-password: passwd

In the documentation I found I should use command
koha-create --request-db <lib-name> ... for that but I miss some example.

For that command there are options --dbhost which really modified generated .txt file. But I don't know, how to set password. Koha still generates password randomly I need to force my password.

Setting --adminuser didn't changed username in request .txt file. Password could be possible to change using --passwdfile but it's not described which format of passwdfile is expected.

Thanks
