grep url 来自文本并在ansible中访问

Question

团队，

我有一个包含 url 的文本文件，我需要使用 uri anisible 模块启动它并捕获其结果以检查 http_status 代码是否为 200。我的剧本在下面，但我收到错误：

当我使用 vars 文件中定义的变量时，同样的工作。但是当我从 GREP 结果的输出中使用它时它不起作用。如果我切换我的评论它有效。那就是如果我使用

url: https://'{{ site_from_vars_file }}'

-
  name: Test connectivity to target servers
  hosts: all
  vars_files:
           - vars.yaml
      - name: "GREP API server name..  "
        shell: "grep 443 $HOME/.kube/config/cluster-user.kubeconfig | awk -F '//' '{print }'"
        register: grep_output
        ignore_errors: true
      - debug:
          var: grep_output.stdout_lines
        when: grep_output.stdout != ''

      - name: "Validate site reachability response as 200 okay  "
        uri:
          #url: https://'{{ site_from_vars_file }}'
          url: https://'{{ grep_output }}'
          return_content: yes
          validate_certs: no
        register: uri_output
        failed_when: uri_output.status not in [200]

输出：

这似乎是问题所在：

url: https://'{{ grep_output }}'

您需要将其更改为以下内容：

url: https://'{{ grep_output.stdout }}'
url: https://'{{ grep_output.stdout_lines }}'

你的游戏现在看起来像这样:

- name: "Validate site reachability response as 200 okay  "
  uri:
    #url: https://'{{ site_from_vars_file }}'
    url: https://'{{ grep_output.stdout }}'
    return_content: yes
    validate_certs: no
  register: uri_output
  failed_when: uri_output.status not in [200]
