Make sure to obtain and assign an "elastic IP" so that the instance has a static IP
You can see what keys were added to the machine
<code>juju authorised-keys list</code>
and verify the key fingerprint for the key you want to use
<code>ssh-keygen -lf /home/user/.ssh/id_rsa</code>
but you have to know/guess what user was installed by your charm
<code>ssh -i /home/user/.ssh/id_rsa -o IdentitiesOnly=true -vvv ubuntu@ec2-55-5-555-55.compute-1.amazonaws.com</code>
