Question

我有一个jinja模板需要填充我的服务器的辅助IP。

我尝试运行以下操作，这比我需要的更多。

 tasks:
  - name: debug2
    debug: msg={{ ansible_enp0s8_iface1.ipv4_secondaries }}

结果

ok: [localhost] => {
"msg": [
    {
        "address": "172.16.2.20", 
        "broadcast": "172.16.2.255", 
        "netmask": "255.255.255.0", 
        "network": "172.16.2.0"
    }
]
}

然而，当我运行以下

时

tasks:
  - name: debug2
    debug: msg={{ ansible_enp0s8_iface1.ipv4_secondaries.address }}

我收到以下致命错误，表明＆＃34;地址＆＃34;未定义。我不确定为什么会这样，因为它与主界面完美配合

fatal: [localhost]: FAILED! => {"failed": true, "msg": "the field 'args' has an invalid value, which appears to include a variable that is undefined. The error was: 'list object' has no attribute 'address'\n\nThe error appears to have been in '/root/test.yml': line 15, column 5, but may\nbe elsewhere in the file depending on the exact syntax problem.\n\nThe offending line appears to be:\n\n    #debug: msg={{ ansible_enp0s8_iface1.ipv4_secondaries.address }}\n  - name: debug1\n    ^ here\n"}

Answer 1

请注意ipv4_secondaries显示在方括号中，这样您就知道它是一个列表。

所以你应该从列表中选择一个元素，例如：

ansible_enp0s8_iface1.ipv4_secondaries[0].address

ansible ipv4辅助IP过滤
