Overview

Class: seed_stack::router

listen_port

The port that Nginx should listen on when serving requests.

domain

The domain that Nginx should serve for routing.

nginx_manage

Set to false to avoid managing the nginx package.

Parameters:

  • listen_addr (Any) (defaults to: $seed_stack::params::router_listen_addr)
  • listen_port (Any) (defaults to: $seed_stack::params::router_listen_port)
  • domain (Any) (defaults to: $seed_stack::params::router_domain)
