I would like to copy my winetricks cache over to the docker container:
HOST:
~/.cache/winetricks
to CONTAINER
/home
https://docs.docker.com/storage/volumes/#choose-the--v-or-mount-flag
@Charles Duffy is right.
dockerfile below
VOLUME ["(change-to-full-path)/.cache/winetrick"]
lanch value below
-v (change-to-full-path)/.cache/winetricks:/home/myUser/.cache/winetricks
This will allow you to set a volume, and then path it into the container
