Bringing Dockerfiles into Vercel Functions

·2026.06.30 09:00

Key point

Vercel Functions now supports deploying HTTP servers via a Dockerfile or Containerfile.

Details

Vercel Functions now supports the ability to deploy HTTP servers using OCI (Open Container Initiative) compatible images. This allows developers to easily run applications written in any language on top of Vercel's infrastructure.

Bringing an existing application into Vercel lets you enjoy the following benefits.

  • Preview Deployments
  • Logs
  • Routing
  • Autoscaling

To use it, simply create a Dockerfile.vercel or Containerfile.vercel file at the project root that contains an HTTP server listening on $PORT. The resulting image is automatically built, pushed, and deployed via the Vercel Container Registry on every commit.
