Exit handlers

If you ever wanted to have some post orchestration steps that are run regardless of success of failure of the project you can now define exit_handlers using the library.

What is an exit handler ?

An exit_handler is a common step that will be called after your full orchestration ran. Independent to the results of the steps, allowing you the capacity to do some clean up / reporting / any action required after a run.

How to define an exit handler ?

By making use of the library, you can add a specific template folder called on_exit

Every template defined in this folder will be registered as an exit handler ensuring it will be ran after the orchestration is finished.

What do I need to know about those handlers ?

First ALL defined exit handlers will be run in alphabetical order, so if you have multiple library plugins adding handlers ALL of those will be run.

Second they use the exact same syntax as any command template so you can define environment variables, arguments and more.

But one environment variable is added to their list by csm-orc : CSM_ORC_IS_SUCCESS which is a boolean value set to True if the orchestration was a success, and set to False if ANY step failed.
