Where are Docker images stored on the host machine?

Question

I managed to find the containers under directory /var/lib/docker/containers, but I can\'t find the images.

What are the directories and files under

Answer 1

If anyone need it for scripting purposes, here is a one-line solution.

In POSIX shell, with PCRE enabled grep, try:

DOCKER_ROOT_DIR="$(docker info 2>&1 | grep -oP '(?<=^Docker Root Dir: ).*')"

In PowerShell:

$DOCKER_ROOT_DIR="$(docker info 2>&1 | foreach {if($_ -match "Docker Root Dir"){$_.TrimStart("Docker Root Dir: ")}})"

Note, when on Windows 10 (as of 10.0.18999.1), in default configurations, it returns:

• C:\ProgramData\Docker in "Windows containers" mode
• /var/lib/docker, in "Linux containers" mode
