安塞 bool 错误! 'retries' 不是任务包含的有效属性

Question

我的要求是运行脚本 stop-all 多次(重试 5 次)，直到 ps -fu user1 |wc -l 的输出小于 2 .

我为此编写了以下 ansible 剧本:

cat stop.yml

  - hosts: dest_nodes
    tasks:
      - name: Start service
        include_tasks: "{{ playbook-dir }}/inner.yml"
        retries: 5
        delay: 4
        until: stopprocesscount.stdout is version('2', '<')


cat inner.yml

      - name: Start service
          shell: ~/stop-all
          register: stopprocess

      - name: Start service
          shell: ps -fu user1 |wc -l
          register: stopprocesscount

但是，我在运行 playbook 时遇到以下错误。

ERROR! 'retries' is not a valid attribute for a TaskInclude

The error appears to be in '/app/playbook/stop.yml': line 19, column 9, but may
be elsewhere in the file depending on the exact syntax problem.

The offending line appears to be:


      - name: Start service
        ^ here

你能推荐一下吗？

首先，更正 inner.yml 中任务的缩进。其次，从 stop.yml 中删除 retries、delay 和 until 并将它们移至特定任务，因为这些是任务电平参数。

由于您需要基于另一任务重试一项任务，因此您可以将脚本和命令结合起来并提取 wc -l 命令的结果，如下所示:

由于 stdout_lines 将包含字符串列表，并且版本需要 int，因此需要进行转换。

inner.yml

  - name: Start service
    shell: ~/stop-all; ps -fu user1 | wc -l
    register: stopprocesscount
    retries: 5
    delay: 4
    until: stopprocesscount.stdout_lines[stopprocesscount.stdout_lines | length - 1] | int  is version('2', '<')

stop.yml

  - hosts: dest_nodes
    tasks:
      - name: Start service
        include_tasks: "{{ playbook-dir }}/inner.yml"
