There are various ways you could go about doing this. Here's one of them.
users.yml
---
- hosts: all
sudo: yes
tasks:
- name: add users
user: name="{{ item.key }}" comment="{{ item.value.comment }}"
when: inventory_hostname in groups.{{ item.value.hosts|join(',') }}
with_dict: users
tags: user
- name: add sshkey for users
authorized_key: user="{{ item.key }}" key="{{
item.value.authorized|join() }}"
when: inventory_hostname in groups.{{ item.value.hosts|join(',') }}
with_dict: users
tags: user
vars.yml
users:
user1:
comment: "user2"
authorized:
- "ssh-rsa aaa"
- "ssh-rsa bbb"
hosts: [ "all", "office" ]
user2:
comment: "user3"
authorized:
- "ssh-rsa ccc"
hosts: [ "office" ]
hosts:
[something]
hostX
[office]
hostY
[all:children]
something
office
$ ansible-playbook -i hosts users.yml --tags user --extra-vars @vars.yml
I accept this is not the most elegant way to do it, but it's just something
I came up with on the spot.
Hope it helps,
Dan.
