ansible ipv4輔助IP過濾

我有一個jinja模板，需要填充我的服務器的輔助ip。ansible ipv4輔助IP過濾

我試着運行下面的代碼，它比我所需要的要多一點點。

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

結果

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，當我運行以下

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

我得到以下致命錯誤指示「地址」是不確定的。我不知道爲什麼會這樣，因爲它與主界面

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"}

注意ipv4_secondaries顯示在方括號中，這樣，你知道，這是一個列表完美的作品。

所以，你應該從列表中選擇一個元素，例如：

ansible_enp0s8_iface1.ipv4_secondaries[0].address

謝謝。正是我在找什麼。我會對元素提示做一個心理記錄。 – crusadecoder
