When you launch an instance and explicitly name it using:

juju deploy lamp website1

Is there a way on the newly created instance to get the data that tells the machine that its:

• called website1

or even better:

• a unit number such as website1/0, website1/1 etc etc

The reason for doing this is that in my charm I wish to set the hostname to this value.

I did wonder if it was set via ec2metadata but it doesn't seem to list this information.
