[chef] LWRPs and rolling back

["Florian Hehlen" < >]

HI all,

 

I am writting my own LWRP for my server. So I have the following actions:

 

actions :stop, :db_backup, :update, :validate, :db_rollback, :server_rollback, :start

 

creating the resource/provider is working pretty well. I am wondering though how I can express the workflow logic in the recipe to roll-back only if the validation fails.

 

I see some possibilities with handlers, or with the only_if/not_if properties, notifiers/subscribers but none of them scream out as the way to go. Are there any suggestions on best practices here?

 

cheers,

Florian
