Is it possible to output the list of image ids that the container is not currently running? This command prints the id list of all the images in the output, but I only want the images that do not have an active container.

docker images -q

Finally, I want to remove the images that do not have an active container delete HDD so that the limited space of the server is not full. Currently, I am using this command docker rmi $(docker images -q), because some of the images have an active container, an error is encountered and the cd job fails. If you know of a bash script that can help, add it.

CodePudding user response：

There is a docker command that deletes images that do not have an associated running container:

• docker image prune
  allows you to clean up dangling images (a dangling image is not tagged and not referenced by any container)
• docker image prune -a
  will remove all images that are not used by any existing containers
• docker image prune -a --filter "until=48h"
  you can add a filter (--filter) to limit the images to be pruned, as in this example, only images that are older than 48 hours

You can add the -f or --force flag to prune the images and not prompt for confirmation

You could use this in a scheduled bash script to keep your drive tidy
