image is being used by stopped container

Question

I am trying to delete a docker container by this command:

docker rmi 

Obviously, I have replaced the Image-Id by the Id I get u

Answer 1

You must remove container first.
Forced is the last method to take.

#check container
docker ps -a

#remove container
docker rm containerID

Answer 2

You need to delete the stopped container with docker rm, and then you can delete the image it uses with docker rmi.

Answer 3

Docker containers run on top of docker images, you can delete an image only if it is not attached to any container.! So you have to stop container and remove container then you can remove image id.

docker stop container-id and docker rm container-id

Then try removing image docker rmi image-id
