Docker: How to link external folder while building dockerfile

I need to link an external folder, on the host, while building a docker image. I do not want to copy this folder due to its large size, and it is shared over the hosts that run the container.

What is the proper way to do this? I am planning to mount this folder when running the container.

You can't do it with the default Docker build engine. But you can do it with Docker buildkit using the new syntax: https://github.com/moby/buildkit/blob/master/frontend/dockerfile/docs/syntax.md#build-mounts-run---mount

The instructions on how to enable buildkit is on the same page
