Why is the
docker image prune -a command not reclaiming any space?
$ docker container ls CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
No containers running.
$ docker image ls REPOSITORY TAG IMAGE ID CREATED SIZE awsdevenv latest 41d1e7913346 2 minutes ago 1.57GB <none> <none> da7eb8c6161b 52 minutes ago 1.57GB
My (probably incorrect) understanding is that
docker image ls shows 1.57GB x 2 used space for these images.
$ docker image prune -a WARNING! This will remove all images without at least one container associated to them. Are you sure you want to continue?

But the total reclaimed space is the shown as 0. Why is this?
