Como aceitar a entrada do usuário usando vars_prompt e linha de comando?

Já faz alguns meses que comecei a jogar com o Ansible. Neste tutorial, veremos como usar a vars_prompt ansible section se você desejar prompt the user uma determinada entrada enquanto executa o playbook ansible.

Vamos começar:

Passo 1

Crie o arquivo hosts e coloque-o na pasta chamada /Users/Shared/ansible .

hosts

[ local ]
localhost ansible_connection = local ansible_python_interpreter = python
 
[ defaults ]
host_key_checking = false
 
[ crunchify ]
localhost

Passo 2

Coloque seu arquivo ansible.cfg padrão na mesma pasta.

1
2
3
4
[ defaults ]
ansible_ssh_user = crunchify
inventory = hosts
host_key_checking = false

Etapa 3

Crie o arquivo crunchify.yml no qual usaremos a seção vars_prompt para obter a entrada do usuário.

- hosts : crunchify
   connection : local
   vars_prompt :
 
    - name : website
       prompt : "What is your website?"
       private : no
 
    - name : country
       prompt : "Enter Country Name?"
       private : no
 
   tasks :
 
    - debug :
         msg : 'Website name: {{ website }}. Country name: {{ country }}'

Passo 4

Execute o playbook ansible.

Como ignorar o prompt do usuário e aceitar argumentos via linha de comando:

1
bash - 3.2 $ ansible - playbook - vvv crunchify . yml - e "website='Crunchify.com' country='United States'"
