Unifi network; small proxmox vms for core services; big truenas box for movies, storage, "apps ecosystem" stuff like minecraft servers; baremetal 12 node k8s cluster on opi5s for "research" (coz I do lots of k8s at work).
Each "stage" above is like incremental failure domains, unifi only keeps internet working, core vms add functionality (like unifi mgmt, rancher, etc), truenas is for "fun extras" etc. k8s lab has nothing I need to keep on it because distributed storage operators are still kind of explodey.
Like each part makes sense individually but when I look at the whole thing I start to question my mental health.
Imagine simplest possible deployment you've cooked up.
Now imagine explaining your mother how to maintain it after you're dead and she needs to access the files on the service you setup.
usually, selfhosting is not particularly hard. It's just conceptually way beyond what the average joe is able to do. (Not because they're not smart enough, but simply because they never learned to and will not learn now because they don't want to form that skill set. And I'm not hating on boomers, you can make the same argument with your hypothetical kids or spouse. The parents are just an easy placeholder because you're biologically required to have them, which isn't the case for any other familial relationship)
why does it have to be a non-technical next of kin ? Write down the details for a technically inclined person to follow, maybe a specific friend. Print at the top of the page “show this to X”. In the document explain how to recover the necessary data and replace the setup with a standard one.
I assume most people know at least one person who would do this for them , in the event of their death?
