我看到Ansible提供了一些我们可以在攻略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。通过谷歌搜索文档，我找不到所有可用变量的列表。

有人能帮我把它们列出来吗？

ansible
ansible-facts

我使用这个简单的攻略：

代码语言：javascript
复制
---
# vars.yml
#
# Shows the value of all variables/facts.
#
# Example:
#
#   ansible-playbook vars.yml -e 'hosts=localhost'
#
- hosts: localhost
  tasks:
    - fail: "You must specify a value for `hosts` variable - e.g.: ansible-playbook vars.yml -e 'hosts=localhost'"
      when: hosts is not defined

- hosts: "{{ hosts }}"
  tasks:
    - debug: var=vars
    - debug: var=hostvars[inventory_hostname]

有很多变量被定义为事实-- http://docs.ansible.com/ansible/playbooks_variables.html#information-discovered-from-systems-facts

注意，关于连接配置变量或“行为”变量的官方文档在Inventory文档中似乎是List of Behavioral Inventory Parameters。

附注：sudo选项在那里是没有文档的(是的，它的sudo不是您所期望的ansible_sudo ...)也许更多的人不是，但这是我在他们身上找到的最好的医生。
