Bring your Dockerfile to Vercel Functions

Vercel announced support for deploying custom Docker containers as Vercel Functions, enabling developers to use Dockerfiles to define their function environments and dependencies. This feature allows for greater flexibility and customization compared to standard serverless function deployments, as users can specify exact runtime configurations and system packages within their Docker images. The capability streamlines the process of migrating existing containerized applications to Vercel's serverless platform.
