What

Docker Disk Usage on the Monitoring page no longer shows untagged images as <none>:<none>. Each one gets the name it really has, plus a subtitle that says why Docker keeps no tag for it.

Case	Before	After
An image from an earlier deploy: its tag moved to a newer build, and an exited swarm task still holds it	<none>:<none> · Dangling local image	ghcr.io/agenthits/dokploy:agenthits-dev · Previous version: the tag now points to another image
A compose image pulled by digest (redis:8-alpine@sha256:…)	<none>:<none> · Dangling local image · Used by: no containers reported	redis:8-alpine · Pulled by digest, no local tag · Used by: the running containers
An old pull that no container uses	<none>:<none>	registry/app@sha256:<12 chars> · Dangling local image

Why

Docker drops an image's tag once the tag moves to another image, and it never stores a tag for an image pulled by digest. The image's real name is still in the reference its containers were created from (Config.Image) and in RepoDigests. The page used only the REPOSITORY/TAG columns of docker system df -v.

How

• The name comes from the container references, running containers first. When no container uses the image, it comes from RepoDigests.
• Containers are matched to images by image id from docker container inspect. docker ps has no image id, and it shows a bare id once the tag has moved, so digest-pinned containers used to be missed.
• Used by marks containers that are not running, e.g. panel.1.abc (exited). That is what keeps an old image on disk, and why docker image prune leaves it there.
• Remote servers are unchanged: they still get only the summary.

Checks

• New unit test for the three cases. The existing test was updated to the new container shape.
• Full Vitest suite: 4303 passed, 5 skipped. tsc --noEmit for packages/server and apps/dokploy, Biome on the changed files: clean.
• The new code ran on real docker system df -v, image inspect and container inspect output from a production host. All 28 untagged images got a name. For all 46 images, the Used by count matched the CONTAINERS column of docker system df -v.
