Chef-Client Exit Codes

Signal outside tools of specific Chef-Client run status. Ability to determine results of a Chef-Client run.


As a Chef user,
I want to be able to determine when a chef-client run is rebooting the node,
so that Test-Kitchen/Vagrant/any outside tool can wait for node to reboot, and continue converging.


Exit codes Reserved by Operating System

Remaining Available Exit Codes

All exit codes defined should be usable on all supported Chef Platforms. Also the exit codes used should be identical across platforms. That limits the total range from 1-255. Exit codes not explicitly used by Linux/Windows are listed below. There are 59 exit codes that are available on both platforms. * Any numbers below that have a strike-through are used below in the Exit Codes in Use section * Exit Codes Available for Chef use : * ~~35,37,40,41,42~~,43,44,45,46,47,48,49,79,81,90,91,92,93,94,95,96,97 * 98,99,115,116,168,169,172,175,176,177,178,179,181,184,185,204,211 * ~~213~~,219,227,228,235,236,237,238,239,241,242,243,244,245
