Hi folks sorry if this is a dumb question, but I'm fairly new to Usenet and although I have it all set up, I saw some instructions to use a docker to run SABnzbd in?
I've been using it for about a month without one, but I'm worried there might be adding security or privacy risk?
Definitely not necessary. A lot of use cases for SABnzbd are for some sort of media server or NAS, which is where docker comes in handy. If you don't already have a docker setup, and don't intend to have one in the future, running a single app as a container probably isn't going to be necessary. There are other considerations of course, but as far as security goes, as long as you're connecting via SSL and/or VPN, you should be good.
So you want to run your usenet client now. What about torrents later? Then you find out about all the *arr applications, then plex. What if you want to remove one of them? You'll end up with a difficult time to configure all your applications, maintaining them, and cleaning up if needed. Port number conflicts, dependencies, etc. With docker, it's much easier to do all of that, and the instructions are widely available.
