编辑存放用户名和密码的.yml文件

vim userlist.yml
---
userlist:
  - user: user1
    pass: '123'
  - user: user2
    pass: '456'
  - user: user3
    pass: '789'

编辑创建用户的.yml文件
[[email protected] ansible]# cat createuser.yml

---
  - hosts: webserver
    vars_files:
    - userlist.yml
    tasks:
    - name: create user
      user:
        name: "{{ item.user }}"
        password: "{{ item.pass | password_hash('sha512') }}" 
        state: present
      loop: "{{ userlist }}"

对存放用户名和密码的.yml文件进行加密,并输入密码:
ansible-vault encrypt userlist.yml
cat结果如下

[[email protected] ansible]# cat userlist.yml 
$ANSIBLE_VAULT;1.1;AES256

查看加密后的文件内容(注意需要输入密码)
如果需要编辑使用命令

ansible-vault edit userlist.yml
[[email protected] ansible]# ansible-vault view userlist.yml
Vault password: 
---
userlist:
  - user: user1
    pass: '123'
  - user: user2
    pass: '456'
  - user: user3
    pass: '789'

使用加密的方式创建用户

ansible-playbook createuser.yml --ask-vault-pass

验证时可以使用ssh或者直接cat ./etc/passwd

user1:x:1001:1001::/home/user1:/bin/bash
user2:x:1002:1002::/home/user2:/bin/bash
user3:x:1003:1003::/home/user3:/bin/bash

踩坑日志:
注意yml文件的格式需要先验证,格式空格都要对,不然会报错。
我遇到的报错如下
fatal: [192.168.0.91]: FAILED! => {"msg": "Invalid data passed to 'loop', it requires a list, got this instead: { { (userlist, wantlist=True) }}. Hint: If you passed a list/dict of just one element, try adding wantlist=True to your lookup invocation or use q/query instead of lookup."}
解决办法
参考的教程时别人的格式有问题,这几个写到一行就好了。

- name: create user
  user:
    name: "{{ item.user }}"
    password: "{{ item.pass | password_hash('sha512') }}" 
    state: present
  loop: "{{ userlist }}"
