当已注册变量ansible task中存在字符串时

团队

我有两个任务，一个是保存输出以注册变量，另一个是检查其中是否存在字符串。但这是一个调用synatx的错误。观察到任何暗示吗

我需要为此设定事实吗？如果是，怎么做

- name: "Capture DiskCache enablement event via isc pod log"
  command: kubectl logs -n isc-vdiskplugin "{{ item }}" vdisk | grep \"Disk Cache Enabled\"
  delegate_to: localhost
  become: false
  register: isc_pod_log
  with_items: "{{ isc_pod.stdout }}"
  ignore_errors: no
  tags: tag_post_dcro

- name: check variable registered
  debug:
    var: isc_pod_log.stdout

- name: Validate DiskCache is enabled from isc pod logs
  when: "Disk Cache Enabled" in isc_pod_log.stdout
  debug: msg="Disk Cache is Enabled"
  ignore_errors: no
  delegate_to: localhost
  become: false
  tags: tag_post_dcro

输出：

[Pipeline] }
   ERROR! Syntax Error while loading YAML.
     expected <block end>, but found '<scalar>'

   The error appears to be in '/ansible-managed/jenkins-slave/slave0/workspace/run_ansible_playbook/k8s/baremetal/roles/diskcache_prerequisites/tasks/main.yml': line 116, column 19, but may
   be elsewhere in the file depending on the exact syntax problem.

   The offending line appears to be:

   - name: Validate DiskCache is enabled from isc pod logs
     when: "Enabled" in isc_pod_log.stdout
                     ^ here
   This one looks easy to fix. It seems that there is a value started
   with a quote, and the YAML parser is expecting to see the line ended
   with the same kind of quote. For instance:

       when: "ok" in result.stdout

   Could be written as:

      when: '"ok" in result.stdout'

   Or equivalently:

      when: "'ok' in result.stdout"

可能是我的名单？我无法查找

fatal: [node1]: FAILED! => {"msg": "The conditional check ''Disk Cache Enabled' in sci_pod_log.stdout' failed. The error was: error while evaluating conditional ('Disk Cache Enabled' in sci_pod_log.stdout): Unable to look up a name or access an attribute in template string ({% if 'Disk Cache Enabled' in sci_pod_log.stdout %} True {% else %} False {% endif %}).\nMake sure your variable name does not contain invalid characters like '-': argument of type 'AnsibleUndefined' is not iterable\n\nThe error appears to be in '/home/dtlu/code/disable-fscache/tasks/main.yml': line 28, column 3, but may\nbe elsewhere in the file depending on the exact syntax problem.\n\nThe offending line appears to be:\n\n\n- name: Validate DiskCache is enabled from csi pod logs\n  ^ here\n"}

当出现以下情况时，引用整个

：

- name: Validate DiskCache is enabled from isc pod logs
  when: "'Disk Cache Enabled' in item.stdout"
  debug: msg="Disk Cache is Enabled"
  ignore_errors: no
  delegate_to: localhost
  become: false
  tags: tag_post_dcro
  with_items: "{{ isc_pod_log }}"

我们需要使用循环，因为返回是一个列表

- name: Validate DiskCache is enabled from sci pod logs
  when: "'Disk Cache Enabled' in item.stdout"
  debug: msg="Disk Cache is Enabled"
  ignore_errors: no
  delegate_to: localhost
  loop: "{{ sci_pod_log.results }}"
  tags: tag_post_dcro

可能是我的isc_pod_日志是一个列表，我需要迭代？如果是这样的话，我用你的答案的输出更新了问题。是的！修复了一个问题，但遇到了另一个问题。我已经在注册的变量上添加了循环，
isc\u pod\u log
。现在我们使用
item.stdout
。
- name: Validate DiskCache is enabled from sci pod logs
  when: "'Disk Cache Enabled' in item.stdout"
  debug: msg="Disk Cache is Enabled"
  ignore_errors: no
  delegate_to: localhost
  loop: "{{ sci_pod_log.results }}"
  tags: tag_post_dcro
