-====== Docker - Remove dangling images ======
-Docker images consist of multiple layers.
-Dangling images are layers that have no relationship to any tagged images.
-  * They no longer serve a purpose and consume disk space.
-  * They can be located by adding the filter flag, -f with a value of dangling=true to the docker images command.
-  * When you're sure you want to delete them, you can add the -q flag, then pass their ID to docker rmi:
-To list dangling images:
-<code bash>
-docker images -f dangling=true
-</code>
-To remove dangling images:
-<code bash>
-docker rmi $(docker images -f dangling=true -q)
-</code>
-or
-<code bash>
-docker rmi $(docker images --filter "dangling=true" -q --no-trunc)
-</code>

-An alternative to listing dangling images:
-<code bash>
-docker images | awk '/<none>/ { print $3 }'
