Will this sequence of steps completely delete an image from disk in the Docker Trusted Registry? Solution: Delete the image and run garbage collection on the Docker Trusted Registry.

If other references to an image's layers exist after an initial image deletion, running garbage collection will not remove those layers from disk.

Simply deleting an image (e.g., untagging it) does not guarantee its complete removal from disk because other tags, manifests, or even other repositories might still reference its underlying layers; for complete deletion, all references to the image's layers must be removed before garbage collection can reclaim the space.
