我正在尝试枚举我的eth0地址（设置为默认值，因为我在某处读到 eth0 并不总是可用..）。在我的模板中，我尝试像这样从组中调用它......

这似乎应该是可用的，因为当我倾倒时-debug var=groups我得到......
[18.234.92.196] => {
"groups": {
......
"controller": [
"54.86.253.135",
"52.205.43.24",
"54.210.213.10"
],
"controller.0": [
"54.86.253.135"
],
"controller.1": [
"52.205.43.24"
],
"controller.2": [

],
......

"52.205.43.24"
],
"name_controller-2": [
"54.210.213.10"
],
......
}
}
奇怪的是，当我尝试调试时，var=groups[controller]我得到...
TASK [worker : debug] *******************************************************************************************************************************************
ok: [34.207.172.100] => {
"groups[controller]": "VARIABLE IS NOT DEFINED!: 'controller' is undefined"
}
.....
TASK [worker : Add Kubelet configuration] ***********************************************************************************************************************
fatal: [34.207.172.100]: FAILED! => {"changed": false, "msg": "AnsibleUndefinedVariable: 'controller' is undefined"}
我在这里想念什么？
