How to find active docker images and volumes?

Question

I can see docker disk using the docker system df command:

$ docker system df
TYPE            TOTAL     ACTIVE    SIZE      RECLAIMABLE
Images          31        1         12.86GB   12.81GB (99%)
Containers      1         0         0B        0B
Local Volumes   25        1         17.24GB   17.19GB (99%)
Build Cache     244       0         6.249GB   6.249GB

The output shows one image and one volume are active. How can I find these active objects?

I don't think I have any active objects because docker ps displays no results. Perhaps these are internally managed docker objects?

Answer 1

docker ps -a solved the problem
