Role Handlers

Role Variables

Nginx configuration

The elao_nginx_config_template key will allow you to use differents main configuration templates. The role is shipped with basic templates :

• base (Simple template with no default configuration)
• dev (This configuration will keep serving NGINX informations like server tokens and provide directives for Vagrant VM)
• test
• prod (For production purpose. Cleaning all sensible server informations)

Example:

elao_nginx_config_template: config/http_dev.conf.j2

The elao_nginx_config key is made to allow you to alter main Nginx configuration templates.

Example:

elao_nginx_config:
  user: nginx
  events:
    worker_connections: 1024

Exclusivity
