I'm not familiar enough with Ansible or Docker to really risk installing Lemmy straight onto the VPS so I'm thinking of putting Yunohost on it.
If I chose the Hetzner Cloud package with 8GB RAM and 80Gb space, realistically, how many users could sign up before things got dangerous.
Hetzner is fine with yunohost installs and the hardware specs are good for it, I'm just wondering about Lemmy capacity in terms of numbers of users. I realise you'd only be able to guesstimate a ballpark figure.
Also, one way to cut down on space use is apparently object storage. I know I can use Backblaze for this - how exactly is this configured? Is there a setting in the lemmy config to point to external object storage providers?
Yunohost currently only packages an old version of Lemmy AFAIK. So until they update it, I would not use it to host Lemmy.
Lemmy is currently more CPU than RAM limited.
80gb storage will last you quite some time as Lemmy currently does not proxy images from remote instances. So only small thumnails and images that users from your instance upload are stored on your server. This might change in the future though, as image-proxying helps with load-balancing a lot.
