PostgreSQL Setup for Foundry REST API Relay

This setup provides persistent storage using PostgreSQL instead of the default SQLite or memory database.

Quick Start​

  1. Start the services:

    docker-compose -f docker-compose.postgres.yml up -d

  2. Initialize the database:

    # Wait for PostgreSQL to be ready (about 10-15 seconds), then run:
    docker-compose -f docker-compose.postgres.yml exec relay pnpm run db:migrate

  3. Check the logs:

    docker-compose -f docker-compose.postgres.yml logs relay

Full Setup Steps​

# 1. Start PostgreSQL first and wait for it to be ready
docker-compose -f docker-compose.postgres.yml up -d db

# 2. Wait for database to be ready (healthcheck will ensure this)
docker-compose -f docker-compose.postgres.yml ps

# 3. Initialize the database schema and create admin user
docker-compose -f docker-compose.postgres.yml exec relay pnpm run db:migrate

# 4. Start the relay service
docker-compose -f docker-compose.postgres.yml up -d relay

# 5. View logs to confirm everything is working
docker-compose -f docker-compose.postgres.yml logs -f relay

Default Database Credentials​

  • Database: foundryvtt_relay
  • Username: postgres
  • Password: example
  • Host: localhost (from host machine) or db (from within Docker network)
  • Port: 5432

Default Admin User​

After initialization, a default admin user is created:

  • Email: admin@example.com
  • Password: admin123
  • API Key: Generated automatically (check logs for the key)

Environment Variables​

You can customize the PostgreSQL setup by modifying the environment variables in docker-compose.postgres.yml:

# Database configuration
- POSTGRES_DB=foundryvtt_relay        # Database name
- POSTGRES_USER=postgres              # Database user
- POSTGRES_PASSWORD=example           # Database password

# Relay configuration
- DATABASE_URL=postgres://postgres:example@db:5432/foundryvtt_relay

Stopping and Cleanup​

# Stop services
docker-compose -f docker-compose.postgres.yml down

# Stop and remove all data (WARNING: This deletes all data!)
docker-compose -f docker-compose.postgres.yml down -v

Troubleshooting​

Database Connection Errors​

If you see connection errors, make sure:

  1. PostgreSQL is running: docker-compose -f docker-compose.postgres.yml ps
  2. Database is healthy: Check the healthcheck status
  3. Wait a bit longer for PostgreSQL to start up completely

Reinitialize Database​

If you need to reset the database:

# Stop services
docker-compose -f docker-compose.postgres.yml down

# Remove the database volume (WARNING: Deletes all data!)
docker volume rm foundryvtt-rest-api-relay_postgres_data

# Start fresh
docker-compose -f docker-compose.postgres.yml up -d db
docker-compose -f docker-compose.postgres.yml exec relay pnpm run db:migrate
docker-compose -f docker-compose.postgres.yml up -d

Data Persistence​

All PostgreSQL data is stored in a Docker volume named foundryvtt-rest-api-relay_postgres_data. This ensures your data persists between container restarts and updates.
