Adds a user public SSH key to the host's ~/.ssh/authorized_keys via docker container
docker run -v /root:/user -e AUTHORIZED_KEYS="`cat ~/.ssh/id_rsa.pub`" tutum/authorizedkeys
With multiple keys:
docker run -v /root:/user -e AUTHORIZED_KEYS="`cat ~/.ssh/id_rsa1.pub`,`cat ~/.ssh/id_rsa2.pub`" tutum/authorizedkeys
Adding the key to a specific user:
docker run -v /home/myuser:/user -e AUTHORIZED_KEYS="`cat ~/.ssh/id_rsa.pub`" tutum/authorizedkeys
