From ba3e59cbb5ae58a2267fcbcd23eecaaa26f2c396 Mon Sep 17 00:00:00 2001 From: Scott Moser Date: Tue, 8 Sep 2015 16:53:59 -0400 Subject: power_state: support 'condition' argument if 'condition' is provided to config in power_state, then consult it before powering off. This allows the user to shut down only if a condition is met, and leave the system in a debuggable state otherwise. An example is as simple as: power_state: mode: poweroff condition: ['sh', '-c', '[ -f /disable-poweroff ]'] --- doc/examples/cloud-config-power-state.txt | 9 +++++++++ 1 file changed, 9 insertions(+) (limited to 'doc') diff --git a/doc/examples/cloud-config-power-state.txt b/doc/examples/cloud-config-power-state.txt index 8df14366..b470153d 100644 --- a/doc/examples/cloud-config-power-state.txt +++ b/doc/examples/cloud-config-power-state.txt @@ -23,9 +23,18 @@ # 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. # power_state: delay: "+30" mode: poweroff message: Bye Bye timeout: 30 + condition: True -- cgit v1.2.3
