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 地址为 ansible_eth0.ipv4.address。通过 Google 搜索并搜索文档，我找不到所有可用变量的列表。
有人可以帮我列出它们吗？
最佳答案
来自FAQ :
How do I see a list of all of the ansible_ variables?
Ansible by default gathers “facts” about the machines under management, and these facts can be accessed in playbooks and in templates. To see a list of all of the facts that are available about a machine, you can run the
setupmodule as an ad hoc action:ansible -m setup hostnameThis will print out a dictionary of all of the facts that are available for that particular host. You might want to pipe the output to a pager.This does NOT include inventory variables or internal ‘magic’ variables. See the next question if you need more than just ‘facts’.
这是我的名为 scdev 的 vagrant 虚拟机的输出:
