Reverse Proxy

You will need to have a reverse proxy setup. I use a variant of jwilder/nginx-proxy. Traefik and Caddy2 are popular choices.

See administration/install_docker for Lemmy docs on setup and configuration.

Initial Setup

1. Copy samples/env to ./.env and set variables
2. Copy samples/postgres.env.secrets and samples/pictrs.env.secrets to ./ and add the postgres and pictrs passwords respectively
3. Copy samples/config.hjson and samples/postgresql.conf to config and change appropriately
4. Do required setup for your pre-existing reverse proxy, see the labels in the docker-compose.yml for an example for traefik
5. Run setup/init.sh

Updating

1. Update image tags in your .env file
2. docker-compose pull
3. docker-compose down
4. docker-compose up
