Ansible Playbook语法问题 - 当：列表

Question

我收集我的本地主机上的事实。

localhost | SUCCESS => { 
    "ansible_facts": { 
     "ansible_dns": { 
      "nameservers": [ 
       "192.168.1.2", 
       "192.168.1.3" 
      ], 
      "search": [ 
       "example.com", 
      ] 
     } 
    }, 
    "changed": false 
} 

我需要能够访问域名服务器：192.168.1.2和192.168.1.3

我曾尝试以下，仍然可以得到一个错误的语法。我没有看到任何在线文档，告诉我如何访问嵌套值。

# Method 1 
- name: Allow httpd access to files on CIFS volumes that are labeled with the cifs_t type 
    seboolean: name=httpd_use_cifs state=true persistent=yes 
    when: ansible_dns == nameservers == '192.168.1.2' and ansible_dns == nameservers == '192.168.1.3' 

# Method 2 
- name: Allow httpd access to files on CIFS volumes that are labeled with the cifs_t type 
    seboolean: name=httpd_use_cifs state=true persistent=yes 
    when: nameservers == '192.168.1.2' and nameservers == '192.168.1.3' 

Answer 1

您可以访问嵌套的元素与点：ansible_dns.nameservers。

不知道你要构造什么样的条件，但可能的方式之一：
when: "'192.168.1.2' in ansible_dns.nameservers and '192.168.1.3' in ansible_dns.nameservers"
