Redis – Docker can't remove image

I have several Docker images on my pc

PS C:docker_tstarchive> docker image ls
REPOSITORY                                 TAG          IMAGE ID       CREATED         SIZE
redis                                      5-alpine     2d3a8f80f74a   10 days ago     29.3MB

PS C:docker_tstarchive> docker image rm redis

Error: No such image: redis

Why docker can’t find this immage?

    Use the IMAGE ID: docker image rm 2d3a8f80f74a.
    You’re trying to remove a image based on repository and you might have more than one image for repository (e.g: php:7.2-apache, php:7.2-cli, php:latest).

    If you wanna remove all images from the same repository you can do docker rmi $(docker images redis --format "{{.ID}}").

    Use either an image ID or a tag

    ❯ docker image list
REPOSITORY   TAG       IMAGE ID       CREATED       SIZE

    Because you are removing the image based on image name, so you should give the version or it would be assumed that version is latest.
    so use this command to remove the image by name:

    docker image rm redis:5-alpine

    If the image was in use you can force removing by using –

    docker image rm redis:5-alpine -f
