The image could be currently used by a running container  so you first have to stop and remove the container s    docker stop  lt container-name gt  docker rm  lt container-id gt    Then you could try deleting the image   docker rmi  lt image-id gt    You must be sure that this image doesn t depend on other images  otherwise  you must delete them first    I had a strange case in which I had no more containers still alive  docker ps -a returned nothing  but I couldn t manage to delete the image and its image-dependency   To solve these special cases you could force the image removal with this   docker rmi -f  lt image-id gt

Use  docker image prune -all   or  docker image prune -a   Remove all dangling images  If -a is specified  it will also remove all images not referenced by any container   Note  You are prompted for confirmation before the prune removes anything  but you are not shown a list of what will potentially be removed  In addition  docker image ls does not support negative filtering  so it difficult to predict what images will actually be removed   As stated under Docker s documentation for prune

If you want to automatically periodically clean up exited containers and remove images and volumes that aren t in use by a running container you can download the Docker image meltwater docker-cleanup   That way you don t need to go clean it up by hand   Just run   docker run -d -v  var run docker sock  var run docker sock rw  -v  var lib docker  var lib docker rw --restart unless-stopped meltwater docker-cleanup latest   It will run every 30 minutes  or however long you set it using DELAY TIME 1800 option  and clean up exited containers and images   More details  https   github com meltwater docker-cleanup blob master README md

The reason for the error is that even though the image did not have any tag  there still exists a container created on that image which might be in the exited state  So you need to ensure that you have stopped and deleted all containers created on those images  The following command helps you in removing all containers that are not running   docker rm  docker ps -aq --no-trunc --filter  status exited     Now this removes all the dangling non-intermediate  lt none gt  images   docker rmi  docker images --filter  dangling true  -q --no-trunc       Note  To stops all running containers   docker stop  docker ps -q

Simply you can aadd --force at the end of the command  Like   sudo docker rmi  lt docker image id gt  --force   To make it more intelligent you can add as   sudo docker stop   docker ps   grep  lt your container name gt    awk   print  1     sudo docker rm   docker ps   grep  lt your container name gt    awk   print  1     sudo docker rmi   docker images   grep  lt your image name gt    awk   print  3    --force   Here in docker ps  1 is the first column  i e  the Docker container ID   And docker images  3 is the third column  i e  the Docker image ID

Possible reason  The reason can be that this image is currently used by a running container  In such case  you can list running containers  stop the relevant container and then remove the image   docker ps docker stop  lt containerid gt  docker rm  lt containerid gt  docker rmi  lt imageid gt    If you cannnot find container by docker ps  you can use this to list all already exited containers and remove them    docker ps -a   grep 60afe4036d97 docker rm  lt containerid gt    Note  Be careful of deleting all exited containers at once in case you use Volume-Only containers  These stay in Exit state  but contains useful data
