#cloud-config

## poweroff or reboot system after finished
# default: none
#
# power_state can be used to make the system shutdown, reboot or
# halt after boot is finished.  This same thing can be acheived by
# user-data scripts or by runcmd by simply invoking 'shutdown'.
# 
# Doing it this way ensures that cloud-init is entirely finished with
# modules that would be executed, and avoids any error/log messages
# that may go to the console as a result of system services like
# syslog being taken down while cloud-init is running.
#
# If you delay '+5' (5 minutes) and have a timeout of
# 120 (2 minutes), then the max time until shutdown will be 7 minutes.
# cloud-init will invoke 'shutdown +5' after the process finishes, or
# when 'timeout' seconds have elapsed.
#
# delay: form accepted by shutdown.  default is 'now'. other format
#        accepted is +m (m in minutes)
# mode: required. must be one of 'poweroff', 'halt', 'reboot'
# message: provided as the message argument to 'shutdown'. default is none.
# timeout: the amount of time to give the cloud-init process to finish
#          before executing shutdown.
# condition: apply state change only if condition is met.
#            May be boolean True (always met), or False (never met),
#            or a command string or list to be executed.
#            command's exit code indicates:
#               0: condition met
#               1: condition not met
#            other exit codes will result in 'not met', but are reserved
#            for future use.
