loops - ansible 循环 include_tasks 直到成功

Question

我想知道如何循环多个任务直到满足条件。

#main.yml

  - set_fact:
      num: 1
      req_num: 10

  - name:  Start to unregister entities
    include_tasks: output.yml
    loop: "{{ range(num, req_num + 1)|list }}"

#output.yml

  - name: get status
    raw: cat /tmp/output
    register: rawoutput

  - name: copy to localhost
    copy:
      content: "{{rawoutput.stdout}}"
      dest: /tmp/output1
    delegate_to: localhost

  - name: reg output2
    shell: awk something /tmp/output1 |awk '/something/,0' |head -n something |tail -n something > /tmp/output2 ; cat /tmp/output2
    register: output2
    delegate_to: localhost

  - name: compare output2
    debug:
      msg: "{{item}}"
    with_items: "{{ output2.stdout_lines }}"
    until: item == "Synced"
    retries: 2
    delay: 2

#cat/tmp/output2

Synced
Syncing
Synced
Failed

我正在使用this ，但是当子任务失败时，剧本会退出。

我的目标是确保output2中的所有内容都是“已同步”，循环output.yml直到结果是“已同步”，或者在x次尝试后失败。

感谢是否有更好的方法来做到这一点。谢谢谢谢
