Re: don't repeat yourself / copy and paste programming



>  А не поделитесь, пожалуйста, темплейтом Puppet'a для nginx?

Большинство манифестов заточено на нашу внутреннюю архитектуру, поэтому не могу 
показать.
Но некоторыми не специфическими поделится могу.

Вот реальный пример, как эти манифесты используются у нас (убрал несущественное 
здесь и поменял имена/IP):

class site::front::example_com {
    nginx::vhost_front { "example.com":
        ip           => "1.2.3.4",
        ssl          => true,
        ssl_only     => true,
        default_trap => "redirect",
        proxy_pass   => "backend123",
        custom       => "client_max_body_size 64m;",
    }
}

node "front3" inherits "front_common" {
    include nginx::front
    include site::front::example_com
}

    package { "nginx": ensure => present }

    service { "nginx":
