The rules now are generally: bare metal if that’s all the box will do, or it’s main task, container if it’s one of many services, vm if it’s a larger application you might migrate and i/o isn’t your limitation.
The line between container and vm is fuzzy, but bare metal means you’re making a design choice for that machine and if that or another application breaks the machine you’re screwed.
In a way freebsd is amazing for this, you put all applications in jails and don’t use the main userspace much, but the virtualiztion story isn’t quite there yet.
I’ve got a hacked pyqt5 script that does this, I doubt it’s what you want. Adding mysql support and eventually want to be able to have something like limited math functions so you can add all the values in a tree for stuff like total cost.
If you find something better I’d be real interested, I really want web and preferably app support.
Pi4 is powerful enough, barely. 1GB is too low, is there a 1GB Pi4? Thought it was 2GB min? Think recommendation is 4GB min, 8 better.
Storage is the real issue, it takes a lot a day, but it’s all based on unique communities subscribed on the server, so if you have 4 accounts all looking at the same 8 communities it’s the same as 1 guy looking at those 8 communities.
4GB/day for a lot of communities, obviously less for less.
Oh yeah, it’s a 3588, all out of tree, I’m very similar.
