模式一
- name: add several usersuser: name={{ item }} state=present groups=wheelwith_items:- testuser1- testuser2  orwith_items: "{{ somelist }}"

模式2. 字典循环- name: add several usersuser: name={{ item.name }} state=present groups={{ item.groups }}with_items:- { name: 'testuser1', groups: 'wheel' }- { name: 'testuser2', groups: 'root' }

假设字典如下

users:alice:name: Alice Appleworthtelephone: 123-456-7890bob:name: Bob Bananaramatelephone: 987-654-3210可以访问的变量
tasks:- name: Print phone recordsdebug: msg="User {{ item.key }} is {{ item.value.name }} ({{ item.value.telephone }})"with_dict: "{{ users }}"

例如:
- copy: src={{ item }} dest=/etc/fooapp/ owner=root mode=600with_fileglob:- /playbooks/files/fooapp/*

  tasks:- command: echo "msg={{ item.0 }} and {{ item.1 }}"with_together:- [ 1, 2, 3 ]- [ 4, 5 ]result:
changed: [localhost] => (item=[1, 4])
changed: [localhost] => (item=[2, 5])
changed: [localhost] => (item=[3, None])

- name: testhosts: alltasks:- name: Example of looping over a command resultshell: touch /$HOME/{{ item }}with_lines: /usr/bin/cat  /home/fg/test

with_lines 中的命令永远都是在controller的host上运行, 只有shell命令才会在inventory中指定的机器上运行

[section1]
value1=section1/value1
value2=section1/value2[section2]
value1=section2/value1
value2=section2/value2
Here is an example of using with_ini:- debug: msg="{{ item }}"with_ini: value[1-2] section=section1 file=lookup.ini re=true
