I have set up a home server with ubuntu 22.04 and am setting up various instances of ghost on custom domains for various people.
However, I needed to limit the GB that the various admins of the ghost instances installed on my system could use.
How can I set a limit in terms of GB or MB so that at a certain point the upload is blocked? This would be very useful as it would save my storage space a lot.
I’d look into partitioning that server into separate droplets/containers/virtual servers.
Two decades ago (gasp, yes, it was), I had a small flock of real servers running virtual servers with this software: Overview - Linux-VServer. (This was back before every host in existence sold VPS hosting.) It was great because everyone I hosted had the ability to do whatever they needed to do as ‘root’ in their own vservers, but I could put limits on usage so they couldn’t run amok.
YMMV (it HAS been two decades), and it’s very possible there are better options now than there were then!
I ran a web-hosting company and this how we managed per-customer disk space limits-- each customer had a unique unix user that we assigned a quota to.
With Ghost, it normally runs all the instances as a ghost user, so you’ll have to figure out how to customize that user, hopefully in a way that doesn’t break during upgrades or maintenance.
I thought of a similar solution. But before implementing it, I would have liked to see if there was any different solution.
I also thought when the folder reaches a certain weight in GB the front end was disabled leaving only the back end in order to make room. But I don’t know how far it can be done.
