Examples

1) Install nginx with HTTP directives of choices, but with no sites configured and no additionnal configuration:

- hosts: all
  roles:
  - {role: nginx,
     nginx_http_params: ["sendfile on", "access_log /var/log/nginx/access.log"]
                          }

2) Install nginx with different HTTP directives than previous example, but no sites configured and no additionnal configuration.

- hosts: all
  roles:
  - {role: nginx,
     nginx_http_params: ["tcp_nodelay on", "error_log /var/log/nginx/error.log"]}

Note: Please make sure the HTTP directives passed are valid, as this role won't check for the validity of the directives. See the nginx documentation for details.

3) Install nginx and add a site to the configuration.

- hosts: all

  roles:
  - role: nginx
    nginx_http_params:
      - sendfile "on"
      - access_log "/var/log/nginx/access.log"
    nginx_sites:
      bar:
        - listen 8080
        - location / { try_files $uri $uri/ /index.html; }
        - location /images/ { try_files $uri $uri/ /index.html; }
    nginx_configs:
      proxy:
        - proxy_set_header X-Real-IP  $remote_addr
        - proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for

Note: Each site added is represented by list of hashes, and the configurations generated are populated in /etc/nginx/site-available/, a link is from /etc/nginx/site-enable/ to /etc/nginx/site-available

The file name for the specific site configurtaion is specified in the hash with the key "file_name", any valid server directives can be added to hash. Additional configuration are created in /etc/nginx/conf.d/

4) Install Nginx , add 2 sites (different method) and add additional configuration

- hosts: all
  roles:
    - role: nginx
      nginx_http_params:
        - sendfile on
        - access_log /var/log/nginx/access.log
      nginx_sites:
         foo:
           - listen 8080
           - server_name localhost
           - root /tmp/site1
           - location / { try_files $uri $uri/ /index.html; }
           - location /images/ { try_files $uri $uri/ /index.html; }
         bar:
           - listen 9090
           - server_name ansible
           - root /tmp/site2
           - location / { try_files $uri $uri/ /index.html; }
           - location /images/ { try_files $uri $uri/ /index.html; }
      nginx_configs:
         proxy:
            - proxy_set_header X-Real-IP  $remote_addr
            - proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for

5) Install Nginx , add 2 sites, add additional configuration and an upstream configuration block

---
- hosts: all
  roles:
    - role: nginx
      nginx_error_log_level: info
      nginx_http_params:
        - sendfile on
        - access_log /var/log/nginx/access.log
      nginx_sites:
        foo:
           - listen 8080
           - server_name localhost
           - root /tmp/site1
           - location / { try_files $uri $uri/ /index.html; }
           - location /images/ { try_files $uri $uri/ /index.html; }
        bar:
           - listen 9090
           - server_name ansible
           - root /tmp/site2
           - if ( $host = example.com ) { rewrite ^(.*)$ http://www.example.com$1 permanent; }
           - location / {
             try_files $uri $uri/ /index.html;
             auth_basic            "Restricted";
             auth_basic_user_file  auth_basic/demo;
           }
           - location /images/ { try_files $uri $uri/ /index.html; }
      nginx_configs:
        proxy:
            - proxy_set_header X-Real-IP  $remote_addr
            - proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for
        upstream:
            # Results in:
            # upstream foo_backend {
            #   server 127.0.0.1:8080 weight=10;
            # }
            - upstream foo_backend { server 127.0.0.1:8080 weight=10; }
      nginx_auth_basic_files:
        demo:
           - foo:$apr1$mEJqnFmy$zioG2q1iDWvRxbHuNepIh0 # foo:demo , generated by : htpasswd -nb foo demo
           - bar:$apr1$H2GihkSo$PwBeV8cVWFFQlnAJtvVCQ. # bar:demo , generated by : htpasswd -nb bar demo

6) Install Nginx, add a site and use special yaml syntax to make the location blocks multiline for clarity

---
- hosts: all
  roles:
    - role: nginx
      nginx_http_params:
        - sendfile on
        - access_log /var/log/nginx/access.log
      nginx_sites:
        foo:
           - listen 443 ssl
           - server_name foo.example.com
           - set $myhost foo.example.com
           - |
             location / {
               proxy_set_header Host foo.example.com;
             }
           - |
             location ~ /v2/users/.+?/organizations {
               if ($request_method = PUT) {
                 set $myhost bar.example.com;
               }
               if ($request_method = DELETE) {
                 set $myhost bar.example.com;
               }
               proxy_set_header Host $myhost;
             }

7) Example to use this role with my ssl-certs role to generate or copie ssl certificate ( https://galaxy.ansible.com/list#/roles/3115 )

 - hosts: all
   roles:
     - jdauphant.ssl-certs
     - role: jdauphant.nginx
       nginx_configs:
          ssl:
               - ssl_certificate_key {{ssl_certs_privkey_path}}
               - ssl_certificate     {{ssl_certs_cert_path}}
       nginx_sites:
          default:
               - listen 443 ssl
               - server_name _
               - root "/usr/share/nginx/html"
               - index index.html
