How to remove a volume in a Dockerfile

问题:

I'm experiencing the same problem as found here: mkdir .ssh in a Dockerfile, folder is not there?

I'm wondering if there is a way for my dockerfile to remove a volume declared by its parent?

My reasoning for this is that; the volume was declared to mount to an external database, the image I'm creating is for testing purposes and contains the data present for the volume internally. Ideally I don't want to have to populate this in my entry point as it's an expensive operation.

Actually I did have a very similar use case in using an image from production that would be modified for testing. The only chance is to modify the metadata of the parent image. 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.
