Question

在最佳实践页面中，有一个使用 hosts.yml 的示例。对于主机文件:



但是，在文档中，我只能找到用于编写主机文件的 INI 语法。

YAML 中 list 文件的语法是什么？

Answer 1

是的。

已经deprecated在 2012 年的 0.6 版和 reintroduced 中在 2016 年首次包含在 2.1 版中的提交中。

example file GitHub 上包含指南和示例:

• Comments begin with the '#' character
• Blank lines are ignored
• Top level entries are assumed to be groups
• Hosts must be specified in a group's hosts: and they must be a key (: terminated)
• groups can have children, hosts and vars keys
• Anything defined under a hosts is assumed to be a var
• You can enter hostnames or ip addresses
• A hostname/ip can be a member of multiple groups

Ex 1: Ungrouped hosts, put in 'ungrouped' group

ungrouped:
  hosts:
      green.example.com:
          ansible_ssh_host: 191.168.100.32
      blue.example.com:
      192.168.100.1:
      192.168.100.10:

Ex 2: A collection of hosts belonging to the 'webservers' group

webservers:
  hosts:
      alpha.example.org:
      beta.example.org:
      192.168.1.100:
      192.168.1.110:

Ex 3: You can create hosts using ranges and add children groups and vars to a group. The child group can define anything you would normally add to a group

testing:
  hosts:
      www[001:006].example.com:
  vars:
      testing1: value1
  children:
      webservers:
          hosts:
              beta.example.org:
