+# FCTDrive Container Deployment
+
+This document explains how to build and run the FCTDrive application as a container.
+
+## Prerequisites
+
+1. **Build the binaries locally first:**
+   ```bash
+   # Build the Rust CLI tool
+   just build  # or: cargo build --release --target-dir target/
+   
+   # Build the frontend (optional, done in container)
+   cd frontend && npm run build
+   ```
+
+2. **Container runtime** (podman, docker, etc.)
+
+## Building the Container
+
+```bash
+# Build the container image
+podman build -t fctdrive:latest .
+
+# Or with docker
+docker build -t fctdrive:latest .
+```
+
+## Running the Container
+
+```bash
+# Run with volumes for persistent data
+podman run -d \
+  --name fctdrive \
+  -p 3000:3000 \
+  -v ./blobs:/app/blobs:Z \
+  -v ./data:/app/data:Z \
+  -e TINYAUTH_ENDPOINT=http://localhost:3001 \
+  -e TINYAUTH_PUBLIC_ENDPOINT=http://localhost:3001 \
+  -e FCTDRIVE_PATH=/app/data \
+  fctdrive:latest
+```
+
+## Environment Variables
+
+- `TINYAUTH_ENDPOINT` - Internal TinyAuth server URL
+- `TINYAUTH_PUBLIC_ENDPOINT` - Public TinyAuth server URL (for browser redirects)
+- `FCTDRIVE_PATH` - Path to the drive data directory
+- `NODE_ENV=production` (set automatically)
+- `HOSTNAME=0.0.0.0` (set automatically)
+
+## Volume Mounts
+
+- `/app/blobs` - Blob storage directory
+- `/app/data` - Drive metadata/database directory
+
+## Container Features
+
+- **Base image**: Fedora 42
+- **Runtime**: Node.js + npm
+- **Binary**: Pre-built `fctdrive` binary in PATH
+- **User**: Non-root user `fctdrive`
+- **Port**: 3000 (Next.js server)
+- **Build**: Production Next.js build
+
+## Security
+
+- Runs as non-root user (`fctdrive:fctdrive`)
+- Only production dependencies installed
+- Minimal attack surface with focused .containerignore
+
+## Development vs Production
+
+This container is designed for production deployment. For development:
+- Use `just dev` for hot-reloading
+- Mount source code as volumes
+- Use development dependencies
