playbook变量（八）循环迭代

1、基本使用

[[email protected] ansible]# cat testitem.yaml
---
- hosts: date
  remote_user: root

  tasks:
    - name: create some files
      file: name=/data1/{{ item }} state=touch
      with_items:
        - file1
        - file2
        - file3
    - name: install some packages
      yum: name={{ item }}
      with_items:
        - htop
        - sl
        - hping3

2创建多个用户组

[[email protected] ansible]# cat testitem1.yaml
---
- hosts: date
  remote_user: root

  tasks:
    - name: create some groups
      group: name={{ item }}
      when: ansible_distribution_major_version == "7"
      with_items:
        - g1
        - g2
        - g3

2.1、嵌套自变量（指定用户组）

[[email protected] ansible]# cat testitem2.yaml
---
- hosts: date
  remote_user: root

  tasks:
    - name: create some groups
      group: name={{ item }}
      when: ansible_distribution_major_version == "7"
      with_items:
        - g1
        - g2
        - g3
    - name: create some users
      when: ansible_distribution_major_version == "7"
      user: name={{ item.name }} group={{ item.group }}
      with_items:
        - { name: ‘user1‘, group: ‘g1‘ }
        - { name: ‘user2‘, group: ‘g2‘ }
        - { name: ‘user3‘, group: ‘g3‘ }
