Now that we have stored the image in Docker Hub, we can pull it down whenever we need it, to any system that has Docker installed. And since it is a public repository, we don't even need to be logged in.
Run docker logout to prove this.
Next, let's blow away all images and containers on our VM. Type docker system prune --all and then hit "y" when prompted.
This will output something similar to the following:
ubuntu@ubuntu:~$ docker system prune --all
WARNING! This will remove:
- all stopped containers
- all networks not used by at least one container
- all images without at least one container associated to them
- all build cache
Are you sure you want to continue? [y/N] y

We can verify that we do not have any images on the local system:
ubuntu@ubuntu:~$ docker images
REPOSITORY TAG IMAGE ID CREATED SIZE
Ok, lets pull down our image:
docker pull $DHUSER/my_tools:latest
Now when we run docker images we can verify that we have a local copy:
ubuntu@ubuntu:~$ docker images
REPOSITORY TAG IMAGE ID CREATED SIZE
resistor52/my_tools latest b677d5555ad4 About an hour ago 2.04GB
And we can run it:
docker run --rm -it $DHUSER/my_tools
And then confirm our tools are on the container:
which aws az gcloud
And you should see:
sans@5aae26738dd4:~$ which aws az gcloud
/usr/local/bin/aws
/usr/bin/az
/usr/bin/gcloud
Exit the container.
