How do I share a container file with the host using docker volumes?

I'm trying to use a Magento file located on my docker container by mounting a volume with the command:

docker run -it -v /local/path/on/my/host:/var/www/html/app image_id

I can't figure out how to share the container files on my host. I created a symlink for the file but my PHP script on my host says it doesn't exist when I require it.

I followed this tutorial on digital ocean: https://www.digitalocean.com/community/tutorials/how-to-share-data-between-the-docker-container-and-the-host

Any ideas on how to do this?

For a bind mount, you should specify the full path of the file in the container, not its parent folder:

docker run -it -v /local/path/on/my/host:/var/www/html/app/host image_id
                                                          ^^^^^^

Note that for testing, once a container is running, you can also use dockder cp to copy some files at runtime.

docker cp [OPTIONS] SRC_PATH|- CONTAINER:DEST_PATH
