Is it possible to get a Docker container to read a file from host file system not using Volumes?

I have a Python script inside a container that needs to continuously read changing values inside a file located on the host file system. Using a volume to mount the file won’t work because that only captures a snapshot of the values in the file at that moment. I know it’s possible since the node_exporter container is able to read files on the host filesystem using custom methods in Golang. Does anyone know a general method to accomplish this?
