Mid 2022, a friend of mine helped me set up a selfhosted Vaultwarden instance. Since then, my "infrastructure" has not stopped growing, and I've been learning each and every day about how services work, how they communicate and how I can move data from one place to another. It's truly incredible, and my favorite hobby by a long shot.
Here's a map of what I've built so far. Right now, I'm mostly done, but surely time will bring more ideas. I've also left out a bunch of "technically revelant" connections like DNS resolution through the AdGuard instance, firewalls and CrowdSec on the main VPS.
Looking at the setups that others have posted, I don't think this is super incredible - but if you have input or questions about the setup, I'll do my best to explain it all. None of my peers really understand what it takes to construct something like this, so I am in need of people who understand my excitement and proudness :)
Edit: the image was compressed a bit too much, so here's the full res image for the curious: https://files.catbox.moe/iyq5vx.png And a dark version for the night owls: https://files.catbox.moe/hy713z.png
I am sorry, I am but a worm just starting Docker and I have two questions.
Say I set up pihole in a container. Then say I use Pihole's web UI to change a setting, like setting the web UI to the midnight theme.
Do changes persist when the container updates?
I am under the impression that a container updating is the old one being deleted and a fresh install taking its place. So all the changes in settings vanish.
I understand that I am supposed to write files to define parameters of the install. How am I supposed to know what to write to define the changes I want?
Sorry to hijack, the question doesn't seem big enough for its own post.
With containers, most will have a persistent volume that is mapped to the host filesystem. This is where your config data is. When you update a container, just the image is updated(pihole binaries) but it leaves the config files there. Things like your block lists and custom dns settings, theme settings, all of that will remain.
Thank you.
