skyflow

The Scalabe Go Nostr Relay

Early days but have quite a component test coverage and basic tests with Amethyst. Instance running live at relay.nostry.eu (not ready to be relied upon!)

Goals:

• Simple
• Correct
• Horizontally scalable
• Fast

In that order. I want to support as many NIPs as possible but only if I can assure the above goals.

NIPs support

• NIP01

version: "2.1"

services:

    container_name: skyflow
    environment:
      - MONGODB_URI=mongodb://mongo:27017
    expose:
      - 80
    restart: unless-stopped
  mongo:

    volumes:
      - mongo_db_data:/data/db
  caddy:
    build:
      context: ./caddy
    ports:
      - 443:443
    volumes:

Create a folder named caddy and put the Dockerfile and Caddyfile in the folder.

Dockerfile:

FROM caddy:2.6.4
COPY Caddyfile /etc/caddy/Caddyfile

Caddyfile:

relay.example.com:443 {
    reverse_proxy skyflow:80

    tls me@example.com

    log {
        output file /var/log/caddy/nostr.log {
            roll_size 1gb
            roll_keep 1
            roll_keep_for 720h
        }
    }
}

You will have to register a domain and point the DNS to your IP and make sure you have port 443 open in your firewall/router.

You can now connect to your relay in any nostr app with wss://relay.example.com.
