<code>
[grupo]
hostname1
hostname2:2222
hostname3
some_host         ansible_port=2222     ansible_user=manager
aws_host          ansible_ssh_private_key_file=/home/example/.ssh/aws.pem
jumper              ansible_port=5555 ansible_host=192.0.2.50
</code>

== Variavel de grupos ==

<code>
[grupo:vars]
ntp_server=ntp.atlanta.example.com
proxy=proxy.atlanta.example.com
</code>
ou criar /etc/ansible/groups_vars/<nome grupo>
---
ntp_server: acme.example.org
database_server: storage.example.org

== Sub grupos ==
<code>
[web]
hostA

[db]
hostB

[ubuntu:children]
web
</code>

** groups_var com usernames diferente.

* Cliente (servidores clientes)

  * Instalar o ansible.
  * Habilitar o ssh para o server ansible chegar.
  * Copiar a chave para o root
  * Cuidado com ssh root com senha (apenas chave)

* Server comandos.

<code>
# ansible server_or_group -m module_name -a arguments
# ansible all -m ping 
# ansible all -m shell -a "df -lh"
</code>
Não tem chave mas possui senha de root --ask-pass
<code>
ansible-playbook <file>.yml --list-hosts
