Docker Deployment
Production Dockerfile
The production Dockerfile uses a multi-stage build for optimized image size and security.
Build the image
docker build -t pantry:latest -f Dockerfile .
Run the container
docker run -d \
--name pantry \
-p 3000:3000 \
-e NUXT_PUBLIC_SUPABASE_URL=https://your-project.supabase.co \
-e NUXT_PUBLIC_SUPABASE_ANON_KEY=your-anon-key \
pantry:latest
Environment Variables
Required:
NUXT_PUBLIC_SUPABASE_URL- Your Supabase project URLNUXT_PUBLIC_SUPABASE_ANON_KEY- Your Supabase anon/public key
Optional:
PORT- Port to listen on (default: 3000)HOST- Host to bind to (default: 0.0.0.0)
Health Check
The container includes a health check endpoint at /api/health
curl http://localhost:3000/api/health
Expected response:
{
"status": "ok",
"timestamp": "2026-02-25T00:00:00.000Z",
"uptime": 123.456
}
Image Features
- Multi-stage build: Separate build and runtime stages
- Alpine Linux: Minimal base image (~50MB base)
- Non-root user: Runs as unprivileged user (nodejs:1001)
- dumb-init: Proper signal handling and zombie reaping
- Health checks: Built-in container health monitoring
- Production-optimized: Only production dependencies included
Image Size
Approximate sizes:
- Base Alpine + Node.js: ~50MB
- Dependencies: ~150MB
- Built app: ~20MB
- Total: ~220MB
Security
- Runs as non-root user (nodejs)
- No unnecessary packages
- Minimal attack surface
- Regular security updates via Alpine base
Troubleshooting
View logs:
docker logs pantry
Interactive shell:
docker exec -it pantry sh
Check health:
docker inspect --format='{{json .State.Health}}' pantry
