Run any Dockerfile on Vercel

What this post added

This post details the technical implementation of running arbitrary Dockerfiles on Vercel. It explains the workflow involving a `Dockerfile.vercel` file, Vercel's build and storage process on Fluid compute, and the autoscaling and active CPU pricing benefits. It highlights the use of optimized boot images for fast container startup by streaming and decompressing snapshots on demand. The post also discusses the stateless nature of containers and the integration with Vercel's platform primitives, including networking and potential future durable storage. It positions Dockerfile support as a universal deployment method for services not covered by framework detection.
