如何在 Ansible 的 do-until 循环中指定多个条件

How to specify multiple conditions in a do-until loop in Ansible

我正在进行 REST 调用,并希望在继续之前检查我的请求是否已完成。在响应中,我得到了 "PENDING" 或 "IN_PROGRESS" 作为 request_status。我想等到我得到 "COMPLETED" 或 "FAILED"。为此,我想等待 "PENDING" 或 "IN_PROGRESS"

我尝试了很多变体,但都没有成功,最后的尝试如下:

  - name: Wait for the cluster deployment (this will take a while)
    uri:
      url: http://localhost:8080/api/v1/clusters/{{ cluster_name }}/requests/1
      method: GET
      user: admin
      password: admin
      HEADER_X-Requested-By: Ansible
      force_basic_auth: yes
      status_code: 200, 201, 202
      return_content: yes
    register: response
    until: "'{{ (response.content | from_json).Requests.request_status }}' != 'PENDING' AND '{{ (response.content | from_json).Requests.request_status }}' != 'IN_PROGRESS'"
    retries: 3
    delay: 5

错误是:

"The conditional check ''{{ (response.content | from_json).Requests.request_status }}' != 'PENDING' AND '{{ (response.content | from_json).Requests.request_status }}' != 'IN_PROGRESS'' failed. The error was: template error while templating string: expected token 'end of statement block', got 'AND'. String: {% if 'COMPLETED' != 'PENDING' AND 'COMPLETED' != 'IN_PROGRESS' %} True {% else %} False {% endif %}"

所以,我的问题是如何在 Ansible 的 do-until 循环中指定多个条件?

好的,找到问题了。

将 "AND" 更改为 "and" 有效。

until: "'{{ (response.content | from_json).Requests.request_status }}' != 'PENDING' and '{{ (response.content | from_json).Requests.request_status }}' != 'IN_PROGRESS'"

可以(至少使用 Ansible 2.8.3)将数组传递给 until:

- shell: "echo OK"
  until:
    - 1 == 1
    - "'no'.replace('no', 'yes') == 'yes'"

在这种情况下,数组项隐含地 "joined" 和 and
