Docker

Building the Docker Image

Build your application's Docker image using the following command:

Terminal

pnpm docker:build

Running the Container

Run the container with basic configuration:

Terminal

docker run -p 3000:3000 expostarter-web \
  -e BASE_URL=https://your-domain.com \
  -e POSTGRES_URL=postgres://postgres:password@host:5432/dbname

Production Deployment with Docker Compose

Below is a complete example using Docker Compose with Traefik as a reverse proxy, featuring:

Automatic SSL certificate management
PostgreSQL database
Secure HTTPS redirection
Container health checks

docker-compose.yml

services:
  traefik:
    image: traefik:v2.10

Environment Variables

Create a .env file in your project root with these required variables:

.env

# Domain configuration
DOMAIN=your-domain.com
LE_EMAIL=your-email@example.com

# Database configuration
POSTGRES_DB=expostarter
POSTGRES_USER=postgres
POSTGRES_PASSWORD=your-secure-password

# Other required environment variables
UPLOADTHING_TOKEN=your-uploadthing-token
APPLE_AUTH_CLIENT_ID=your-apple-auth-client-id
GOOGLE_SIGNIN_AUDIENCE=your-google-signin-audience

Deployment Steps

Install Docker and Docker Compose on your server
Copy the docker-compose.yml and .env files to your server

Create required directories:

mkdir -p /app/docker-volume/{traefik,postgres}

Start the services:
```
docker compose up -d
```

Troubleshooting

If you encounter issues:

Check container logs: docker compose logs -f [service-name]
Verify environment variables are set correctly
Ensure all required ports are accessible
Check your domain's DNS configuration points to your server
