Insert metadata during launch
When booting a server, you can also add metadata, so that you
can more easily identify it amongst your ever-growing elastic
cloud. Use the --meta option with a key=value
pair, where you can make up the string for both the key and the
value. For example, you could add a description and also the creator
of the server.
$ nova boot --image=natty-image --flavor=2 smallimage2 --meta description='Small test image' --meta creator=joecool
When viewing the server information, you can see the metadata
included on the metadata line:
$ nova show smallimage2
