Docker – Remove Existing Docker Images

I want to remove all the existing docker images from my virtualbox, and I also ran into the errors like this for a few images.

docker_rmi_fail

However, I ran command `sudo docker ps`, I cannot see any running containers and it confused me a lot until I came across this Docker issue3258 on github. In the end, I realized that there is a difference between running and non-running containers which `docker ps` will only list the running ones. You need to remove both types of containers before remove all the images.

Here is the solution in the end:

sudo docker ps -a | grep Exit | awk '{print $1}' | sudo xargs docker rm
sudo docker rmi $(sudo docker images -q)

More information about what the commands do:

`sudo docker ps -a` will list all the information about docker containers including the running one, exited ones..etc.  

docker_rmi_ps_a

Then it pipe the data to extract the image id of the ones that contain Exit then run `docker rm` command, which is used to remove non-running containers.

After that, you can easily remove all the images because no containers will be running. Here is also a helpful post from stackoverflow.
