For example: # You already have an Image that consists of these layers 3333 2222 1111 # You pull an image that consists of these layers: AAAAA <-- You only need to pull (and need additional space) for this layer 22222 11111 I keep getting notifications regarding high docker image utilization which typically clear after a couple of hours. An easy way to decrease the memory usage for me is to docker system prune -a which removes the containers, after that the vmmem memory usage drops to a few gigabytes which I think corresponds quite well to the WSL disk usage. Hi @Franck Dernoncourt! RECLAIMABLE is the space consumed by "unused" images (in the meaning of no containers based on thoses images is running). Here, Docker Desktop displays the path to the disk image file on your Mac's file system, as highlighted below: Note that the disk image is managed by the Docker Desktop virtual machine and is not meant to be manually modified or directly Something went wrong! - Docker Hub The docker image file should only hold the binaries for the container so it is easy to get back to the last working state with the applications in the same state they were before the problem occurred. 06.
