以下是登记册的内容:
- debug:
var: vmfacts.virtual_machines
ok: [localhost] => {
"vmfacts.virtual_machines": {
"2k12r2-k11": {
"guest_fullname": "Microsoft Windows Server 2012 (64-bit)",
"ip_address": "10.0.1.20",
"mac_address": [
"00:50:56:00:00:20"
],
"power_state": "poweredOn",
"uuid": "421d5210-8a64-2d60-8b44-02de952600d1"
},
下面工作正常,但我需要上面的 uuid 值
- shell: "echo {{ item }}"
with_items: "{{ vmfacts.virtual_machines }}"
似乎无法解码语法,这些似乎都不起作用:
“回显 {{ item.uuid }}” “回显 {{ item.0.uuid }}” “回显 {{ item[0].uuid }}”
访问 uuid 值的正确方法是什么?
答案1
vmfacts.virtual_machines
是dict
。
with_items
当应用于dict
仅对其键进行迭代时。
因此,要么:
- shell: "echo {{ vmfacts.virtual_machines[item].uuid }}"
with_items: "{{ vmfacts.virtual_machines }}"
或者更好的用法with_dict
:
- shell: "echo {{ item.value.uuid }}"
with_dict: "{{ vmfacts.virtual_machines }}"
