A place to share alternatives to popular online services that can be self-hosted without giving up privacy or locking you into a service you don't control.

Rules:

  1. Be civil: we're here to support and learn from one another. Insults won't be tolerated. Flame wars are frowned upon.

  2. No spam posting.

  3. Posts have to be centered around self-hosting. There are other communities for discussing hardware or home computing. If it's not obvious why your post topic revolves around selfhosting, please include details to make it clear.

  4. Don't duplicate the full text of your blog or github here. Just post the link for folks to click.

  5. Submission headline should match the article title (don’t cherry-pick information from the title to fit your agenda).

  6. No trolling.

My first try at self hosting, and I have some questions... (lemmy.dbzer0.com)

So, here's what I set up:

Docker with some containers behind Gluetun

Gluetun gives access to the local network so I can access the containers on my home network through http.

The only port I exposed to the internet is the 32400 for Plex.

I reach my home network remotely only through Wireguard, my fritzbox router has a guided setupt that gives me a wg configuration so I just scanned the QR code with my phone. I learned this opens the default wg port.

Now, you can never be 100% safe, but is my simple setup safe/solid enough?

9 times out of 10 I thinker with it when I am at home

It's still a work in progress and I am open to any kind of suggestions

One thing that was recommended to me by someone a while ago, is that, unless you need it for something specific, mount your media in Plex as read only.

Plex has functions where you can delete content from the library from their UI. If you need that for some reason, obviously don't make it read only. If you're hoarding the data, and therefore never delete it, or use an external system for deleting files, then RO all the way.

The only caveat to this is if you're using a local disk on the Plex system, which then shares out the drive/folder for adding new content, in which case, you're screwed. It has to be rw so the OS can add/remove data.

In my case, as I think may be common (or at least, not rare), my back end data for Plex Media is on a NAS, so it's easy to simply have the system running Plex, mount that network share as RO, and you're done. The data on the NAS can be accessed and managed by other systems RW, direct to the NAS.

Since Plex is exposed to the internet, if anyone with sufficient rights is compromised, in theory, an attacker could delete the entire contents of your media folder with it. If you limit RW access to internal systems only, then that risk can be effectively mitigated.
