What is the location of the docker image files on OS/X?

There are several questions regarding how to view docker images on local machine including I can't find my Docker image after building it

The docker images command does report that an image was successfully created:

  • HTTP/2 nginx force redirect HTTP to HTTPS breaks expected behaviour
  • Docker: open /certs/domain.crt: permission denied
  • Iscsid not starting on a centos6 docker on MacOS host
  • Exclude starting some containers with Docker Compose
  • Unable to pull the images in docker on Windows
  • How do I deploy to a remote docker host on windows server 2016?
  • $docker images

    This question is about the physical locations of the docker files – to do operations like copying/backups etc. How would the paths be found on OS/X?

  • What are Selenium Docker image release versions for browser capabilities?
  • How to use STOPSIGNAL instruction within Docker?
  • django postgresql password authentication failed for user
  • ownership of files that are written by the docker container to mounted volume

    On Mac, Docker images are stored within the VM. See this Question.

    On Linux, Docker images are stored in /var/lib/docker, so backing up that directory should be sufficient.

    I don’t think you should be copying images from that directory. The normal way to share a built image between machines is with Docker Hub or with a private Docker registry. If you want to share images that are not published to a registry, you can simply share the Dockerfile.

    Docker will be the best open platform for developers and sysadmins to build, ship, and run distributed applications.
