Docker (Custom : Mediaserver (Network Type))

[Querzion]

So I'm watching THIS VIDEO, because I got really into having Starr dockers from Hotio. . . and in it he has a custom network type that he's named 'mediaserver' and it's especially created for the dockers in mind. He's however forgotten how he created it, and his search frase isn't really helping. I'm pretty sure others will want to know this too, sooner or later. 

Where can I find a guide to create a custom network bridge in unRAID?



SOLUTION HERE >  docker network create 'name of network'
 

 

I made one extra that failed. . . "docker network create qStarr" 
 

How do I delete networks that I don't need?
