you can see that i have several Images with name javaapp:latest and different container name. So, i killed and remove all container of "javaapp:latest" container with:

sudo docker stop "containerName"

sudo docker rm "containrName"

Then

sudo docker rmi -f "imageId"

So i can remove all the images with name "<none>"

goodluck

Expanding on the answer provided by  Nguyen - this function can be added to your  bashrc etc and then called from the commandline to help clean up any image has dependent child images errors     You can run the function as yourself  and if a docker ps fails  then it will run the docker command with sudo and prompt you for your password   Does NOT delete images for any running containers   docker rmi dependants                                                                                                                                                                  DOCKER docker     docker ps  gt  dev null 2 gt  amp 1      DOCKER  sudo docker     echo  Docker    DOCKER      for n in     DOCKER  images   awk   2      lt none gt    print  3       do       echo  ImageID   n         DOCKER  inspect --format     Id      Parent        DOCKER  images --filter since  n -q     done       DOCKER  rmi     DOCKER  images   awk   2      lt none gt    print  3        I also have this in my  bashrc file     docker rm dangling           DOCKER docker     docker ps  gt  dev null 2 gt  amp 1      DOCKER  sudo docker     echo  Docker    DOCKER        DOCKER  images -f dangling true 2 gt  amp 1  gt   dev null  amp  amp  YES                                                                                                                         if    YES -eq 1    then     read -t 30 -p  Press ENTER to remove  or CTRL-C to quit          DOCKER  rmi     DOCKER  images -f dangling true -q     else     echo  Nothing to do    all groovy      fi       Works with     docker --version  Docker version 17 05 0-ce  build 89658be

find the image id and parent id for all image created after the image in question with the following    docker inspect --format     Id      Parent      docker images --filter since  lt image id gt  -q    Then you call command   docker rmi  sub image id      sub image id  is ID of dependent image

I had this issue and none of the short answers here worked  even in the page mentioned by  tudor above  I thought I would share here how I got rid of the images   I came up with the idea that dependent images must be    the size of the parent image  which helps identify it so we can remove it   I listed the images in size order to see if I could spot any correlations    docker images --format     Size   t   Repository   t   Tag   t   ID      sort -h -r   column -t   What this does  is use some special formatting from docker to position the image size column first  then run a human readable sort in reverse order   Then I restore the easy-to-read columns   Then I looked at the  lt none gt  containers  and matched the first one in the list with a similar size   I performed a simple docker rmi  lt image tag gt  on that image and all the  lt none gt  child images went with it   The problem image with all the child images was actually the damn myrepo getstarted-lab image I used when I first started playing with docker   It was because I had created a new image from the first test image which created the chain   Hopefully that helps someone else at some point

Building on Simon Brady s brute force method here  if you don t have a ton of images you can use this shell function   recursive remove image       for image in   docker images --quiet --filter  since   1      do     if     docker history --quiet   image    grep   1         then       recursive remove image    image       fi   done   echo  Removing    1     docker rmi -f   1      and then call it using recursive remove image  lt image-id gt

User · Answer

In some cases  like in my case  you may be trying to delete an image by specifying the image id that has multiple tags that you don t realize exist  some of which may be used by other images  In which case  you may not want to remove the image   If you have a case of redundant tags as described here  instead of docker rmi  lt image id gt  use docker rmi  lt repo tag gt  on the redundant tag you wish to remove

User · Answer

You should try to remove unnecessary images before removing the image   docker rmi   docker images --filter  dangling true  -q --no-trunc    After that  run   docker rmi c565603bc87f

What worked to me was to use the REPOSITORY TAG combination rather than IMAGE ID   When I tried to delete a docker image with the command docker rmi  lt IMAGE ID gt  with no containers associated with this image I had the message     docker rmi 3f66bec2c6bf Error response from daemon  conflict  unable to delete 3f66bec2c6bf  cannot be forced  - image has dependent child images   I could delete with success when I used the command docker rmi RPOSITORY TAG     docker rmi ubuntu 18 04v1 Untagged  ubuntu 18 04v1

Image Layer  Repositories are often referred to as images or container images  but actually they are made up of one or more layers  Image layers in a repository are connected together in a parent-child relationship  Each image layer represents changes between itself and the parent layer   The docker building pattern uses inheritance  It means the version i depends on version i-1   So  we must delete the version i 1 to be able to delete version i  This is a simple dependency    If you wanna delete all images except the last one  the most updated  and the first  base  then we can export the last  the most updated one  using docker save command as below    docker save -o  lt output file gt   lt your image-id gt    gzip  lt output file gt  tgz   Then  now  delete all the images using image-id as below    docker rm -f  lt image-id i gt    docker rm -f  lt image i-1 gt    docker rm -f  lt image-id i-2 gt       lt docker rm -f  lt image-id i-k gt    where i-k   1   Now  load your saved tgz image as below   gzip -c  lt output file tgz gt    docker load   see the image-id of your loaded image using docker ps -q  It doesn t have tag and name  You can simply update tag and name as done below    docker tag  lt image id gt  group name name tag

Just simply use  docker rmi  lt image tag gt  -f  for example  docker rmi ubuntu latest -f   will remove image name ubuntu with tag name latest and -f is for forcefully removal  it worked for me

I also got this issue  I could resolve issue with below commands  this may be cause  the image s  container is  running or exit so before remove image you need to remove container  docker ps -a -f status exited   this command shows all the exited containers so then copy container Id and then run below commands to remove container  docker rm  containerId   this command remove container this may be issue that mention  image has dependent child images   Then try to remove image with below command  docker rmi  ImageId
