# Initiate connection to the OpenStack API (get a token)
# Expects credentials to be available in "OS_"-prefixed env vars

# Query the OpenStack metadata service to find the UUID of the instance we're currently running on

# Here's where you could put other fun stuff, like an email/Slack notification to yourself
