We are using Ansistrano Deploy
roles:
- role: ansistrano.deploy
We want to be able to detect when the deploy fails for any reason (or succeeds), so we can send a Slack notification.
How can we get a return code or similar on this to know the result of the deploy?
Not being familiar under the hood with Ansistrano and more specifically with the error handling already in place inside the role, I'm not entirely sure this will work out of the box.
But my first natural attempt would be to use a block with error handling. This will require to change the way you call the role to use import_role instead of the play-level role: keyword.
Here is a pseudo playbook example to give you the global idea:
- hosts: my_deploy_hosts
tasks:
- name: deploy my_app with some error control
block:
- name: run the ansistrano deploy role
import_role:
name: ansistrano.deploy
- name: If we got there, above ran successfully
debug:
msg: "You should send a ++ message to slack"
rescue:
- name: If we get into this something went wrong
debug:
msg: "Houston. Houston. We have a problem."
