-====== Docker - Remove old and unused images ======
-**docker system prune** will delete **ALL** dangling data.
-i.e. In order: containers stopped, volumes without containers and images with no containers). Even unused data, with **-a** option.
-You also have:
-<code bash>
-docker container prune
-docker image prune
-docker network prune
-docker volume prune
-</code>
-For unused images, use **docker image prune -a** (for removing dangling and ununsed images).
-<WRAP important>
-**WARNING**:  'unused' means "images not referenced by any container": be careful before using **-a**.
-**docker system prune --all** will remove **all** unused images not just dangling ones... which can be a bit too much.
-</WRAP>
-----
-Combining **docker xxx prune** with the **--filter** option can be a great way to limit the pruning ([[https://docs.docker.com/engine/api/sdk/|docker SDK API]]).
-The currently supported filters are:
-  * **until (<timestamp>)** - only remove containers, images, and networks created before given timestamp
-  * **label (label=<key>, label=<key>=<value>, label!=<key>, or label!=<key>=<value>)** - only remove containers, images, networks, and volumes with (or without, in case label!=... is used) the specified labels.
-See **https://docs.docker.com/config/pruning/#prune-images|Prune images]]** for an example.
