ansible module: group_by
ansible中的group_by模块借助Facts可以用来创建匹配特定标准的主机的动态组。- hosts: all
tasks:
- name: Create a group of all hosts by operating system
group_by: key={{ansible_distribution}}-{{ansible_distribution_version}}
#组名中间不要留空格
- hosts: CentOS-6.2 #CentOS-6.2即引用上面group_by创建的value
tasks:
- name: ping all CentOS 6.2 hosts
ping:
- hosts: CentOS-6.3
tasks:
- name: ping all CentOS 6.3 hosts
ping:
附：
Facts are information derived from speaking with your remote systems.
