Clear the entire provision setup if fails to execute even a single command

Question

I'm trying to create and provision aws/ec2 instance. But if it fails, I want to clear the entire setup. Is that possible?

Answer 1

Of course this is possible @Kiara, you can wrap all the tasks in the block/rescue block. Something like this:

- block:
    - name: task 1

    ... # something bad may happen here

    - name: task N

  rescue: 
    - assert: # we need a dummy task here to prevent our host from being failed
        that: ansible_failed_task is defined
