Synology SNMP Network Monitoring with LibreNMS Docker

I am going through this tutorial now. I see in the tutorial, you are running MariaDB in another Docker container. However, I already have a MariaDB set up on my Synology.

I see the line below:

–link mariadb:libredb \

I see that creates a link from the MariaDB container to the LibreNMS container. If I don’t need this link, how could I modify this command? Or can I just remove it?
