我正在编写一个脚本，用于在 vSphere 环境中部署和配置 VM。
部署后，我想收集虚拟机的 IP 以进行 DNS 注册。可以同时收集 2 个或更多虚拟机的信息。但是，如何使用收集到的数据输出带有 IP 地址的虚拟机名称？
对于单个 VM，这可以获取 IP，但是当与 2 个 VM 一起使用时，变量未定义：
- debug:
var: vm_guest_facts.instance.ipv4
也许我的方法是错误的，但我真的不知道该怎么做。
- name: Gather facts from recently deployed VM's
vmware_guest_facts:
validate_certs: False
hostname: "{{ vcenter_hostname }}"
username: "{{ vcenter_user }}"
password: "{{ vcenter_pass }}"
datacenter: "{{ datacenter }}"
name: "{{ item.key }}"
register: vm_guest_facts
with_dict: "{{ vmdetails }}"
- debug:
var: vm_guest_facts
结果（主机名和文件夹是 Terraform，但此示例仅使用 Ansible）：

datacenter']

您可能想要json_query这样使用。在这里，我从中收集事实vmware_guest_facts并在中注册输出no_vm_result。然后，使用它no_vm_result来json_query遍历所有结果并获取ipv4可用于执行任何操作的结果。这是相当简单的事情。
