ansible-nginx-letsencrypt's Introduction

ansible-nginx-letsencrypt

Simple role to install nginx with let's encrypt on debian and configuring a set of reverse proxies.

The roles allows the following configurations:

multiple backends in a single server
multiple backends in multiple servers

For the let's encrypt certificate there are two possibilities:

one combined cert that is used in all of the servers
a single cert for each server

The role defaults to using one combined certificate for all the servers. This behaviour can be changed by setting nginx_single_cert: false. The nginx host marked default: true will get a 'default' flag.

Example set of variables:

  nginx_letsencrypt_email: "[email protected]"
  nginx_hosts: [
    {
      default: true,
      domain_name: "abcde.example.com",
      reverse_hosts: [ 
        {
          protocol: "http",
          path: "",
          host: "127.0.0.1",
          port: "8080"
        },
        {
          protocol: "http",
          path: "/foo",
          host: "127.0.0.1",
          port: "8090"
        }
      ]
    },
    {
      default: false,
      domain_name: "edcba.example.com",
      reverse_hosts: [ 
        {
          protocol: "http",
          path: "/foobar",
          host: "127.0.0.1",
          port: "9000"
        }
      ]
    }
  ]

If for a server there are no reverse_hosts defined, a regular nginx server with the document root being in /var/www/{{ domain_name}} is configured.

Basic Auth

If basic auth is wanted for the server, adding the users variable will enable this:

 nginx_letsencrypt_email: "[email protected]"
  nginx_hosts: [
    {
      default: true,
      domain_name: "abcde.example.com",
      users: [ "username:password", "seconduser:password" ],
      reverse_hosts: [ 
        {
          protocol: "http",
          path: "",
          host: "127.0.0.1",
          port: "8080"
        },
        {
          protocol: "http",
          path: "/foo",
          host: "127.0.0.1",
          port: "8090"
        }
      ]
    }
 ]
