Retry & until

You can retry a task a number of times, or until a condition is met.

One example is to retry tasks that depend on something external, like installing a package that depends on a repository.

---
- name: Retry something
  hosts: all

  tasks:
    - name: Install some package.
      ansible.builtin.package:
        name: some_package
      register: result
      until: result is not failed
      retries: 2
      delay: 10

The retries is the number of attempts after the first one. So a retries: 2 means the job is attempted 3 times.

Assignment

Write a playbook that:

1. Uses the stat to check if a file exists.
2. Retries 9 times, with a delay of 2 seconds.

This solution works.
