AD-HOC
Vamos precisar do ambiente montado.
AD-HOC vs Playbooks
Ad-hoc é quando você executa um comando direto via cli na máquina de destino ou um grupo de máquinas. Porém você só consegue executar um comando de cada vez. Cada comando executado no cli tem os seus parâmetros, e parâmetros são chave valor certo? Quando colocamos esses parâmetros chave-valor dentro de um aquivo yml, ele se transforma em um playbook que na verdade nada mais é do que vários comandos ad-hoc em sequência já definido dentro do arquivo.
Inventario -i
O inventário é o arquivo que defini os hosts. Você pode ter vários arquivos de hosts inclusive separados por grupos e roles que veremos mais pra frente. No comando ad-hoc o path desse arquivo deve ser passado pelo parâmetro -i. Pode ter tanto o nome que o que o ansible consiga resolver ou um ip direto. Se usar o nome ele tem que estar definido em /etc/hosts de onde o ansible esta executando. Por padrão, caso você não passe o inventário ele irá tentar ler o que estiver em /etc/ansible/hosts.
https://docs.ansible.com/ansible/latest/user_guide/intro_inventory.html
Módulos -m
São como funções que o ansible pode executar no dispositivo de destino. Tem módulo pra tudo que você possa imaginar. Se funções em linguagem de programação recebe parâmetros os módulos também recebem.
o comando ansible-doc ajuda a ver a documentaçao dos modulos no cli.
Módulos Arguments -a
Se um módulo tiver argumentos ele deve ser passado com -a. Dentro da string deve ter todos os argumentos em chave e valor.
Exemplo: -a "arg1=x arg2=y arg3=z"
User -u
É um parâmetro que representa qual usuário ele vai logar no ssh do dispositivo de destino. Se o usuário da máquina local for o mesmo que da máquina destino não precisa passar, mas é boa prática sempre passar para evitar qualquer transtorno em automações futuras.
Password -k
Caso não esteja logando com a chave privada é possível passar a senha também com esse parâmetro.
Became -b
Se você passar -b em uma chamada ansible significa que ele vai executar um sudo.
Testando um comando ad-hoc com o módulo Ping
Nesse caso foi feito o comando em todos os dispositivos que estão na no inventario hosts.
https://docs.ansible.com/ansible/2.3/ping_module.htm
[david@david-bon Aula 2]$ ansible -i hosts all -m ping -u ubuntu

Testando um comando Ad-hoc com o módulo Apt
https://docs.ansible.com/ansible/latest/collections/ansible/builtin/apt_module.html#synop
Observe que se executarmos sem o -b da erro de permissão pois não usamos o sudo. Executamos esse comando somente no robot-1.

Modulo Shell vs. Módulo de Command
Na maioria dos casos de uso, os módulos de shell e de comando executam a mesma tarefa. No entanto, existem algumas diferenças principais entre esses dois módulos.
Ao usar o módulo command, os comandos não serão executados por meio de um shell. Consequentemente, variáveis como $HOME não estão disponíveis e operações como, | e & não funcionará neste caso. Se você deseja usar essas variáveis e operações, você precisa usar um módulo de shell.
Se você deseja executar um comando de maneira previsível e segura, é recomendável usar o módulo de command em vez do shell. O módulo de comando não será afetado pelo ambiente do usuário, então é mais seguro do que o módulo shell.
Modulo Copy
https://docs.ansible.com/ansible/latest/collections/ansible/builtin/shell_module.html
Copiando o arquivo file_teste para dentro de /tmp e mostrando depois. Porém alterei o .cfg do ansible que esta nesta pasta definindo o user o inventario e a chave privada para não precisar fazer o ssh-add etc. Logo o comando reduziu.
