ansibleでユーザとssh鍵を一括登録する

9
Last updated at Posted at 2016-01-06

ansibleでユーザ登録からssh公開鍵登録をまとめて行おうとしたのでやり方をまとめました。
LDAPを使うっていうのはとりあえず無しで。

やりたかったこと

  • グループ登録
  • ユーザ登録
  • ユーザの作成済みssh公開鍵をサーバへコピー

利用したもの

  • groupモジュール
  • userモジュール
  • authorized_keyモジュール

作ったもの

tasks/main.yml
- name: Add group
  group: name="{{item.name}}" gid="{{item.gid}}" state="{{item.state}}"
  with_items: "{{group}}"

- name: Add users
  user: name="{{item.name}}" uid={{item.uid}} comment="{{item.comment}}" group="{{item.group}}" state="{{item.state}}"
  with_items: "{{users}}"

- name: Add user ssh keys
  authorized_key: >
     user="{{item.name}}"
     key="{{ lookup('file', item.key) }}"
  with_items: "{{users}}"
vars/main.yml
users:
  - { name: 'user1',  uid: 5001, group: 'users' , comment: 'user1', home: '/home/user1', createhome: 'yes', state: 'present' , key: 'keys/user1'}
  - { name: 'user2',  uid: 5002, group: 'users' , comment: 'user2', home: '/home/user2', createhome: 'yes', state: 'present' , key: 'keys/user2'}

group:
 - { name: 'users', gid: 5000, state: 'present'}

ファイル配置

ロール名は適切につけてください。
