Question

我有以下的playbook打印出三个jenkins服务器上安装的插件列表：

---
- hosts: all
  remote_user: user
  tasks:
      - name: Obtaining a list of Jenkins Plugins
        jenkins_script:
          script: 'println(Jenkins.instance.pluginManager.plugins)'
          url: 'http://server1.usa.com:8080/'
          user: 'admin'
          password: 'password'

      - name: Obtaining a list of Jenkins Plugins
        jenkins_script:
          script: 'println(Jenkins.instance.pluginManager.plugins)'
          url: 'http://server2.usa.com:8080/'
          user: 'admin'
          password: 'password'

      - name: Obtaining a list of Jenkins Plugins
        jenkins_script:
          script: 'println(Jenkins.instance.pluginManager.plugins)'
          url: 'http://server3.usa.com:8080/'
          user: 'admin'
          password: 'password'

然而，这显然不是最有效的方法。我查看了ansible剧本中的循环和变量 - 但我似乎是在圈子里。以下是我到目前为止的情况：

- name: Obtaining a list of Jenkins Plugins
  jenkins_script:
    script: 'println(Jenkins.instance.pluginManager.plugins)'
    url: {{ item  }}
    with_items:
      - 'http://server1.usa.com:8080/'
      - 'http://server2.usa.com:8080/'
      - 'http://server3.usa.com:8080/'
    user: 'admin'
    password: 'password'

以下是错误消息：

fatal: [server]: FAILED! => {"failed": true, "msg": "the field 'args' has an invalid value, which appears to include a variable that is undefined. The error was: 'item' is undefined\n\nThe error appears to have been in '/home/user/varspb.yml': line 5, column 9, but may\nbe elsewhere in the file depending on the exact syntax problem.\n\nThe offending line appears to be:\n\n  tasks:\n      - name: Obtaining a list of Jenkins Plugins\n        ^ here\n"}

我确定这是一个简单的错误，但有人知道我哪里出错吗？

如果您使用HttpStatusCode.NotModified之类的变量启动值，则需要引用它以插入变量{{ item }}。此外，您的yaml和任务块中存在各种格式问题。我设法用这个来修复你的任务：

"{{ item }}"

如何在ansible playbook中循环变量
