Ansible 任务无法在 Ansible 外壳结果的列表输出中搜索字符串

Question

团队，我有以下任务，但我需要在其输出中搜索 sdd，这是一个列表。 列出输出和我的断言失败。我只想根据结果打印一条消息 sdd 在此任务中找到和未找到。

#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

Answer 1

我的错，我在做与逻辑相反的事情。不需要做。 不是搜索("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')
