🚢 Production Deployment

Building the Docker Image

docker build -t my-database:latest .

Security Hardened Deployment

For maximum security in production, use the following Docker run flags:

docker run -d \
  --name my-database \
  -p 5432:5432 \
  -e POSTGRES_PASSWORD=your_secure_password \
  -e POSTGRES_DB=your_database \
  -v /path/to/data:/var/lib/postgresql/data \
  --cap-drop=ALL \
  --cap-add=CHOWN \
  --cap-add=SETUID \
  --cap-add=SETGID \
  --cap-add=DAC_OVERRIDE \
  --security-opt no-new-privileges:true \
  --read-only \
  --tmpfs /tmp:rw,noexec,nosuid,size=100m \
  --tmpfs /run:rw,noexec,nosuid,size=100m \
  --tmpfs /run/postgresql:rw,noexec,nosuid,size=10m \
  --memory=2g \
  --cpus=2 \
  --restart=unless-stopped \
  my-database:latest

Security Flags Explained:

• --cap-drop=ALL --cap-add=...: Drop all capabilities, only add essential ones for PostgreSQL
• --security-opt no-new-privileges:true: Prevent privilege escalation
• --read-only: Make container filesystem read-only
• --tmpfs: Provide writable temporary filesystems for required directories
• --memory/--cpus: Resource limits to prevent DoS
• --restart=unless-stopped: Auto-restart on failure

Environment Variables

• POSTGRES_PASSWORD: Required - database superuser password
• POSTGRES_USER: Optional - default is postgres
• POSTGRES_DB: Optional - default database name
• POSTGRES_INITDB_ARGS: Optional - additional initdb arguments
