ansible - 每个循环变量的ansible显示输出

问题描述

团队，我的以下任务在组中的所有节点上运行，我需要显示循环中使用的每个节点的输出。任何提示？

        command: cat "{{ proc_stats }}"
        register: stats
        delegate_to: "{{ item }}"
        with_items: "{{ groups['kube-gpu-node'] }}"
        failed_when: stats.stdout is not search('FS-Cache')
      - debug:
          var: stats.results[item.item].stdout_lines
        with_items: "{{ groups['kube-gpu-node'] }}"

输出：

TASK [team-services-pre-install-checks : Assure fscache proc stats] *****************************************************************************************************

    "ansible_loop_var": "item",
    "item": "dgx0159",
    "stats.results[item.item].stdout_lines": "VARIABLE IS NOT DEFINED!"
}

当我只使用结果中的索引为一个节点进行调试时，我得到了这个，但我想要所有节点，而不仅仅是一个如何？

      - debug:
          var: stats.results[0].stdout_lines

解决方案

您已经有一个列表status.results，因此您可以对其进行迭代：

      - debug:
          var: item.stdout_lines
        with_items: stats.results

或者从第一个任务中查看项目：

      - debug:
          msg: "result for {{ item.item }} is {{ item.stdout_lines }}"
        with_items: stats.results
