Not quite. --iidfile writes the image id of the build to a file. --cidfile writes the container id of the container to a file. To use the output of --iidfile in a "docker run", instead of specifying an image name call "$(cat <iidfile>)". As an example: docker build --iidfile out/imageid ... docker run ... $(cat out/imageid) --- edit for formatting ---
