Best Practices

• Use multi-stage builds to reduce image size
• Run containers as non-root users
• Add health checks for better monitoring
• Use .dockerignore to exclude unnecessary files
• Optimize layer caching for faster builds
• Use specific base image versions

Security Tips

• Keep base images updated
• Scan images for vulnerabilities
• Use minimal base images (Alpine)
• Don't store secrets in images
• Use read-only filesystems when possible
• Implement proper user permissions

Frequently asked questions

Does it follow Docker best practices?

The generated Dockerfile aims for sensible defaults like ordering steps for layer caching and using appropriate base images, giving you a solid foundation to refine.

What is a multi-stage build and do I need one?

Multi-stage builds compile in one stage and copy only the artifacts into a slim final image, reducing size. They're recommended for compiled languages and production images.

Can I use the output as-is?

It's a strong starting point; review it for your app's specific files, ports, and environment before building for production.
