使用with_items
loops.yml
---
- hosts: all
tasks:
- name: loop
debug: msg="{{item}}"
with_items:
- one
- two
- three
- four
应用
使用循环安装多个软件
---
- hosts: all
tasks:
- name: loop
yum: name="{{item}}" state="present"
with_items:
- nginx
- zabbix
- php
- mysql
使用字典循环
---
- hosts: all
tasks:
- name: loop dicts
debug: msg="key--->{{item.key}},value--->{{item.value}}"
with_items:
- {key: "one", value: "va1"}
- {value: "two", value: "va2"}
使用嵌套循环
---
- hosts: all
tasks:
- name: loop nested
debug: msg="key--->{{item[0]}},value--->{{item[1]}}"
with_nested:
- ['A', 'B']
- ['a', 'b', 'c']
使用散列循环
---
- hosts: all
gather_facts: no
vars:
user:
shan:
name: shan
shell: bash
ceshi:
name: ceshi
shell: zsh
tasks:
- name: debug loops
debug: msg="{{item.key}}"
with_dict: "{{ user }}"
使用文件循环
---
- hosts: all
tasks:
- name: debug loops
debug: msg="{{item}}"
with_fileglob:
- ./*.yml
条件判断循环
---
- hosts: all
tasks:
- name: debug loops
shell: cat /root/ansible
register: hosts
until: hosts.stdout.startswith("Master")
retries: 5
delay: 5
- until: 直到整个文件以Master开始为结束
- retries: 5次
- delay: 延迟五秒
使用jinjia语法的for循环
---
- hosts: all
gather_facts: no
tasks:
- name: debug loops
shell: "{{item}}"
with_items:
- hostname
- uname
register: ret
- name: display loops
debug: msg="{% for i in ret.results %}{{ i.stdout }} {% endfor %}"
