Images, volumes and networks

i on the container list opens the server’s images, volumes and networks, in three tabs. Each is a table with the biggest first.

Tab Shows
Images Name, ID, size, unique size, age, and how many containers use it. Untagged images are marked dangling
Volumes Name, Compose project, size, how many containers use it, driver
Networks Name, ID, driver, scope, attached containers, internal
Key Action
D Remove the selected item. A tagged image is removed by name, so only that tag goes
P Remove the unused items of the tab
A Remove every unused image, tagged or not
r Reload

Every removal shows its docker command first. The confirmation says when the item is in use, and that a volume’s data is deleted for good. Docker’s own networks (bridge, host, none, ingress) cannot be removed.

u on the Images tab asks each image’s registry for the current digest of its tag and compares it with the one the image was pulled with. Nothing is downloaded. The update column then says:

  • up to date;
  • update available;
  • local build: built on the server, nothing to compare with;
  • can't check, with the reason: the registry’s rate limit, no access to a private image, or no docker buildx on the server. See Troubleshooting.

p pulls the selected image. Running containers keep the old image until they are recreated, for example by a redeploy in Dokploy or Coolify.

g on the container list offers the classic commands: docker system df, and pruning stopped containers, images, volumes, networks, build cache, or everything. Each shows the exact command and asks first.
