How can I delete Docker's images?

Question

I\'ve the following images:

alex@alexvps:~$ sudo docker images
REPOSITORY          TAG                 IMAGE ID            CREATED             VIRTUAL SIZE
&         


        

Answer 1

I found the answer in this command:

docker images --no-trunc | grep none | awk '{print $3}' | xargs docker rmi

I had your problem when I deleted some images that were being used, and I didn't realise (using docker ps -a).
