Delete an image you no longer need
Pulled the wrong tag, or just cleaning up disk space? Every image pulled onto the host can be removed from the Library. netplex.'s own built-in tool images and platform-managed images never show up here, so there is nothing to accidentally delete that the platform itself depends on. Docker images are shared across every user on the host, so removing one is an admin action.
Open Library → Docker and pull a small image to have something to delete - here traefik/whoami, a few megabytes.
Every pulled image gets a Delete action on its row - click it to remove the image from the host. There is no confirmation step here on purpose: it only removes the image file, never anything running, so re-pulling it back costs nothing if you change your mind.
Deleting an image never touches labs already using it - a running node keeps its own copy until it is rebuilt. It only stops that tag from being offered for new nodes and frees the disk space. See "Pull a Docker image" and "Import a QEMU/qcow2 VM" for how images get added in the first place.
