Question

我在本地主机上收集事实。

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

我尝试了以下操作，但仍然在语法中出错。我没有看到任何在线文档向我展示如何访问嵌套值。

# 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

您可以使用 dot 访问嵌套元素：ansible_dns.nameservers。

不确定要构建的条件，但可能的方法之一：
when: "'192.168.1.2' in ansible_dns.nameservers and '192.168.1.3' in ansible_dns.nameservers"
