Hi guys!,

I would like to know if there are any ‘try - catch / rollback’ mode, I mean, I’m running a playbook with some tasks, when a given task crashes, I would like to run an external error recovery task ¿Can I do that?

Playbook example:

- hosts: someofthem  
user: myuser  
tasks:  
-name: First task  
action: whatever  
onerror: clean\_and\_exit #this could be task (or a handler)  
-name: Second task  
action: whatever  
onerror: clean\_and\_exit

…  
-name: clean\_and\_exit  
action: do something…

Thanks in advance

You can add “ignore\_errors” on a task and then use the “when” statement

- action: shell foo  
register: foo\_result  
ignore\_errors: True

- action: shell bar  
when: foo\_result | failed

(The " | failed " is basically a wrapper around saying “foo\_result.failed” but is also a bit more smart in some cases like when you get a list back)
