Hi all,

I’m using Ansible 2.5.11, using the EC2 dynamic inventory script. I’m trying to do some tasks over an instance with a role using block and rescue, so if one of the tasks fails, the rescue task runs (removing the instance). But I don’t know why the rescue tasks never runs.

I’m running a playbook which executes the roles, like this:  
`

# Install common packages and tasks, and deploy software

- hosts: tag\_Environment\_Development:&tag\_Role\_Pilot:&tag\_Name\_Backend  
gather\_facts: True  
vars\_files:
- variables-dev.yml  
roles:
- deploy-api  
`

And the role deploy-api/tasks/main.yml looks like this:

Your syntax is wrong, rescue should not have a dash, check the documentation for correct syntax

HI,

Si as far as I understand, and my tests points to int, a block & rescue is needed for every task in a role? Is not applicable to various tasks?

Regards.
