Ansible Playbook语法问题-什么时候:列表

Question

我正在我的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
}

我需要能够访问名称服务器：192.168.1.2和192.168.1.3

我已经尝试了以下操作，但语法仍然出现了错误。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

您可以使用点：ansible_dns.nameservers访问嵌套元素。

不确定要构造什么条件，但其中一种可能的方法是：

when: "'192.168.1.2' in ansible_dns.nameservers and '192.168.1.3' in ansible_dns.nameservers"
