Copying files from Docker container to host

Question

I\'m thinking of using Docker to build my dependencies on a Continuous Integration (CI) server, so that I don\'t have to install all the runtimes and libraries on the agents

Answer 1

If you just want to pull a file from an image (instead of a running container) you can do this:

docker run --rm cat >

This will bring up the container, write the new file, then remove the container. One drawback, however, is that the file permissions and modified date will not be preserved.
