‚ÄčThe un-tagged images and if you no longer used the images, this would be occupied the disk space in your instance so we can remove it. First listing out the docker image and remove which are displaying with

Just listing out the docker image using the command,


$ docker images -a        

REPOSITORY              TAG                 IMAGE ID            CREATED             VIRTUAL SIZE
                                15bdbeb4a883        10 days ago          474 MB
                                eeb5ef226f19        11 days ago          315 MB

                                1fd8e1b0bb7e        13 days ago          102.5 MB\



$ docker images --no-trunc | grep '' | awk '{ print $3 }' | xargs -r docker rmi
--no-trunc  =>  Don't truncate output
grep          =>  Filter the tag
awk           =>  Filter the image ID
xargs        =>   Converts input from standard input into arguments to a command
docker rmi =>  Remove one or more docker images

Still if the docker image is not removing and showing the report like below you can add an option "--force"
