I have a Dockerfile extending FROM an image that declares a VOLUME. Is there a way to overwrite the VOLUME directive in such a way, that it "removes" the VOLUME?

docker-compose docker

There are cases when you can not modify the original Dockerfile - in my case an image from production. The only chance is to modify the metadata (with docker save/load actions). As I need to that regulary, I have created a little script for that, have a look at docker-copyedit if that can help you.

You may overwrite files. Use multistage build and COPY (docker 19.03). One stage Create files outside of VOLUME'd folder. Or at same RUN step which add/modify files copy it outside of that folder. Next stage COPY files from previous stage to VOLUME'd folder.
