Hi Docker Experts,

I have a vendor provided docker image. Which I have it in my docker registry.

I have simple Docker File which uses this image as a BASE image.

1. Would like to copy a file from the docker image to host
2. update the copied file on the host
3. Copy updated file back to docker in the same location
4. build docker with new tag

please help

Simple Dockerifle

RUN echo foo > bar
COPY /tmp/test.txt /tmp/test_upd.txt

For me even simple COPY is failing
lstat tmp/test.txt: no such file or directory
