How can I remove a stubborn docker image?
I was trying to remove a Docker image as follows and could not figure out how to do this.
List of docker images
$ docker images
REPOSITORY TAG IMAGE ID CREATED VIRTUAL SIZE
<none> <none> 04251cf7a8b9 About a minute ago 356.1 MB
pg-image latest 1060b3e656b6 5 minutes ago 323.9 MB
redis-image latest 8df469463da3 14 minutes ago 137.7 MB
ubuntu 12.04 822a01ae9a15 2 weeks ago 108.1 MB
Docker image I’d like to remove:
$ docker rmi 042
Error response from daemon: Conflict, cannot delete 04251cf7a8b9 because
the container 4ac3a09ab4d3 is using it, use -f to force
2014/08/27 15:16:15 Error: failed to remove one or more images
When I attempted to remove it using -f it was unsuccessful. How do I properly remove this image, and why can I not remove it using docker rmi -f 042?
The issue here is that there’s a container, 4ac3a09ab4d3, that’s still utilizing this image.
$ docker ps -a
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES

You need to remove this container first so that you can remove this image.
# removes container 4ac3a09ab4d3
$ docker rm 4ac
# removes image 04251cf7a8b9
$ docker rmi 042

And with that both the container (4ac3a09ab4d3) and image (04251cf7a8b9) have been removed from your system.
