This appears to fix #572 for us.
We see occasional failures from
cloud-init
failing to communicate with the EC2 metadata endpoint. These appear in systemd as a failure of thecloud-final
service. By addingOnFailure=poweroff.target
, the instance will power itself off when this occurs and allow the ASG to replace it instead of hanging around in a hung state forever.
