Question

团队，我有以下任务，但我需要在列表中的输出中搜索sdd。列出输出，而我的断言失败。我只想打印一条消息sdd，但根据结果在此任务上找不到。

#Local volume provision sdd check on CPU node
      - name: "Verify LVP Mounts sdd exists on CPU Nodes for mount_device"
        shell: "mount | grep sdd"
        register: lvp_mount
        ignore_errors: yes
        failed_when: False
        delegate_to: "{{ item }}"
        with_items: "{{ groups['kube-cpu-node'] }}"

      - set_fact:
          sdd: lvp_mount.results[0].stdout_lines
        when: lvp_mount is succeeded
      - debug:
          var: lvp_mount.results[0].stdout_lines
      - debug:
          msg: "Assert SDD Mounts present"
        failed_when: lvp_mount.results[0].stdout_lines[0] is search('sdd')

输出

我不好，我在做逻辑上的对立。不需要做。不是search（'sdd'）

      - name: "Verify LVP Mounts sdd exists on CPU Nodes for mount_device"
        shell: "mount | grep sdd"
        register: lvp_mount
        ignore_errors: yes
        failed_when: False
        delegate_to: "{{ item }}"
        with_items: "{{ groups['kube-cpu-node'] }}"
      - debug:
          msg: "Assert SDD Mounts present"
        failed_when: lvp_mount.results[0].stdout_lines[0] is not search('sdd')

ansible任务无法从ansible shell结果中搜索列表输出中的字符串
