Instructions on how to COPY to docker container after creating a tarball?

[DaveCole]

Hey there - great action tool, thank you - I'm using this to copy an entire folder to a docker container without worrying about the details of ignore files for... reasons. I tried archiving to yolo.tar.gz and then am attempting to COPY yolo.tar.gz /app but docker is reporting that the file /yolo.tar.gz is not found. Ideas?
