Lemmy Post Purger (LPP)

Instances can grow fast, and that can be a problem if you have limited disk space. If you don't mind losing history that your users have not interacted with, LPP can help. It will purge posts along with their comments and media before a certain time period if no comments, likes, or saves exist for users on your instance.

Usage

In docker-compose:

version: '2.1'

services:

  lpp:
    image: nowsci/lpp
    container_name: lpp
    environment:
      LOCAL_URL: https://lemmy.domain.ext
      LOCAL_USERNAME: top_level_admin_user
      LOCAL_PASSWORD: password
      PURGE_OLDER_THAN_DAYS: 365
      HOURS_BETWEEN_PURGES: 24
      PG_HOST: lemmy_db_host
      PG_PORT: 5432
      PG_DATABASE: lemmy
      PG_USERNAME: lemmy
      PG_PASSWORD: lemmy_db_password
    restart: unless-stopped

Manually:

cd src
export LOCAL_URL=https://lemmy.domain.ext
