Question

团队，我的下面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。有什么提示吗？

        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!"
}

当我使用结果中的索引仅调试一个节点时，我得到了，但是我想要所有节点，而不仅仅是一个方法呢？

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

您在status.results中已经有一个列表，因此您可以对其进行迭代：

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

或者要查看第一个任务中的项目：

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

每个循环变量的显示输出
