我看到 Ansible 提供了一些我们可以在剧本和模板文件中使用的预定义变量。例如，主机 IP 地址是ansible_eth0.ipv4.address。谷歌和搜索文档我找不到所有可用变量的列表。 有人会为我列出它们吗？
ansible_eth0.ipv4.address
从常见问题解答：
如何查看所有 ansible_ 变量的列表？ 默认情况下，Ansible 会收集有关受管理机器的“行为”，并且可以在剧本和模板中访问这些事实。要查看有关机器的所有可用事实的列表，您可以将setup模块作为临时操作运行： ansible -m setup hostname 这将打印出该特定主机可用的所有事实的字典。您可能希望将输出通过管道传输到寻呼机。这不包括库存变量或内部“智能”变量。如果您需要的不仅仅是“行动”，请参阅下一个问题。

这是我的流浪虚拟机的输出，名为scdev：
