Ansible vmware_vm_inventory：如何访问动态主机变量？

Question

我正在使用 Ansible 2.9，我的最终目标是创建所有 运行 带有标签 test[=32= 的虚拟机的快照]. 但我似乎无法访问 name

以外的变量

VMware 清单

plugin: vmware_vm_inventory
strict: False
hostname: < hostname >
username: < username > 
password: < password >
validate_certs: False
with_tags: True

我可以通过变量获取虚拟机的名称：名称，但我还需要状态来确定虚拟机是 运行 还是 [=24] =]guest.guestState 返回未定义。 我如何访问这些变量？

Answer 1

因为 vars 中有一个特殊字符，jinja2 通常为成员访问保留该字符，因此您需要对该 var 使用 dict 键语法：

- debug:
    msg: guest state = {{ vars["guest.guestState"] }}
