Adds a user public SSH key to the host's ~/.ssh/authorized_keys via docker container
Full Description

authorizedkeys

Adds a user public SSH key to the host's ~/.ssh/authorized_keys using a container

Usage

docker run -v /root:/user -e AUTHORIZED_KEYS="`cat ~/.ssh/id_rsa.pub`" dockercloud/authorizedkeys

With multiple keys:

docker run -v /root:/user -e AUTHORIZED_KEYS="`cat ~/.ssh/id_rsa1.pub`,`cat ~/.ssh/id_rsa2.pub`" dockercloud/authorizedkeys

Adding the key to a user different than root:

docker run -v /home/myuser:/user -e AUTHORIZED_KEYS="`cat ~/.ssh/id_rsa.pub`" dockercloud/authorizedkeys

Usage in Docker Cloud

We recommend using this image in Docker Cloud as follows:

authorizedkeys:
  image: dockercloud/authorizedkeys
  deployment_strategy: every_node
  autodestroy: always
  environment:
    - AUTHORIZED_KEYS=ssh-rsa AAAAB3NzaC1y....
  volumes:
    - /root:/user:rw

Is there a way to use this in docker cloud to set multiple keys?

Is there a way to harden the security of docker cloud nodes when using this?
This should really be disabling tunnelling with a password/forcing key only login.
