Template

Continuando com a partir da aula 3 vamos utilizar o módulo setup que trás o facts do ansible e utilizar os valores coletados dentro do html do index do Nginx.

O Módulo template nada mais faz do que fazer uma interpolação utilizando os facts do ansible para dentro de algum file.

No playbook playbook 3 utilizando o módulo copy para copiar o index para dentro do sistema, mas poderíamos trocar o módulo copy para template e fazer interpolação de variáveis em tempo de execução.

Para fazer essa interpolação o ansible utiliza o jimja logo o arquivo tem que estar em extensão .j2
