version: "3.7"

# 1. Have this docker compose file along with the lemmy.hjson and nginx.conf in the same directory
#  a. https://raw.githubusercontent.com/LemmyNet/lemmy/main/docker/nginx.conf
#  b. https://raw.githubusercontent.com/LemmyNet/lemmy/main/docker/lemmy.hjson
# 2. In the lemmy.hjson file edit ((hostname: "localhost")) to your actual host (eg. hostname: "lemmy.example.com")
#  a. You can also change the admin_username (the admin_password and site_name can be changed later)
# 3. In the same directory create a folder called 'pictrs' and 'postgres'
# 4. Edit ownership of pictrs folder user:group of 991:991. CLI example: chown 991:991 pictrs
# 5. In this directory from CLI you can now run: docker-compose up -d
# 6. Lemmy should now be up on http://(ip_address):1236
#  a. If it is on a VPS you might need to temporarily open up firewall to access it publically for testing (CLI example: ufw allow 1236). Make sure you close it afterwards (CLI example: ufw disable 1236).
# 7. This docker compose setup is now ready to be put behind a reverse proxy
