docker COPY without save point
I would like to COPY a really big file from the host filesystem to the guest
but I want to use the file immediately in a shell script and throw it away, so that the save point is AFTER the script.
However, it would appear that
COPY creates a save point and anybody using my resulting image will have to download this large file. In my case, this results in about 5GB of needless data.
Is there a way to copy a file from the local filesystem without invoking a save point?
