Selfhosted
A place to share alternatives to popular online services that can be self-hosted without giving up privacy or locking you into a service you don't control.
Rules:
-
Be civil: we're here to support and learn from one another. Insults won't be tolerated. Flame wars are frowned upon.
-
No spam posting.
-
Posts have to be centered around self-hosting. There are other communities for discussing hardware or home computing. If it's not obvious why your post topic revolves around selfhosting, please include details to make it clear.
-
Don't duplicate the full text of your blog or github here. Just post the link for folks to click.
-
Submission headline should match the article title (don’t cherry-pick information from the title to fit your agenda).
-
No trolling.

I'm running it in the smallest VPS of vultr with 25GB of disk.
This instance only has 3 users, with me being the only active. It says it's been up for almost a month and I've only used 3GB.
Here are the docker volumes which have the actual data of your instance, and from inside the DB the biggest table is the one called
activity
which the devs said it's only sometimes used to validate the data, but could be truncated if needed (there's a schedule task which only keeps up to 6 months).Also the thing to have in mind is to properly configure the logs of whichever installation guide you follow.
After that I've seen other admins say the next biggest is the media uploaded (from bigger instances).
The
activity
table is also used to deduplicate incoming federation data, so instead of truncating it, I'd suggest deleting rows after a certain amount of time.For my personal instance, I set up a cron to delete entries older than 3 days, and my db is only ~500MB with a few weeks of content! I also haven't seen any duplicated posts or comments. Even with Lemmy's retries, 3 days seems to be long enough before dropping rows from that table.
Could you share the cron/script you use to do this? I'm interested in hosting my own Lemmy at some point, and having a script for that cleanup would be hugely helpful for me.
Definitely! I'm hosting in Kubernetes so I won't post the full thing, but here's the actual command that I run hourly. Make sure to replace the values for
database

.Awesome, that was just as straightforward as I was hoping it was, thanks! I am more familiar with MySQL as I haven't used Postgres a ton but SQL is SQL after all lol
