The ansible_role_nginx from ecaepp

Nginx

This role is built to deploy Nginx on an Ubuntu 16.04.

Requirements

Ansible 2.4

Configuration

All options in this section are configured as defaults for Nginx and are defined in defaults.yml so that they can easly be overwritten within the playbook.

Self Signed Cert Generation

The Role has an option for generating a self signed TLS cert for testing. This setting is set to false defaultly to prevent unwanted self signed cert generation.

selfsigned_cert: false # Generate self signed SSL cert.

Configuratoin Files

All options in this section are configured as defaults for Nginx and are defind in defaults.yml so that they can easly be overwritten within the playbook.

This role currently creates three conf files.

nginx.conf
general.conf
server.conf (vhost)

nginx.conf

This file contains options for cofiguring global options pretaining to the Nginx service.

general.conf

This conf file is used to set security headers, restrict access to . files, and compression options.

# Security Headers
header_options: |
  add_header X-Frame-Options "SAMEORIGIN" always;
  add_header X-XSS-Protection "1; mode=block" always;
  add_header X-Content-Type-Options "nosniff" always;
  add_header Referrer-Policy "no-referrer-when-downgrade" always;
  add_header Content-Security-Policy "default-src * data: 'unsafe-eval' 'unsafe-inline'" always;
  add_header Strict-Transport-Security "max-age=31536000; includeSubDomains; preload" always;
# . files

# svg, fonts

fonts_expire: 78
fonts_access_log: "off"

# Gzip

gzip_proxied: any
gzip_comp_level: 6
gzip_types: 'text/plain text/css text/xml application/json application/javascript application/xml+rss application/atom+xml image/svg+xml'

**NOTE:** This file is likely to be deprecated in future when I have time to rewrite the conf file tasks.

server.conf

This file is used to configure Nginx to actually server the web application. This role generates these files from a template in the task tasks/configure.yml.

Currently the options below are required for Nginx to be able to run the app

server_name
listen_port
root_dir
index_name

vhost: []
  - server_name: test.com
    listen_port: 80
    root_dir: /var/www
    index_name: index.html

    ssl:
      cert_dir: /etc/nginx/ssl
      crt: '/etc/nginx/ssl/server.crt'
      key: '/etc/nginx/ssl/server.key'

    security_headers:
      transport_security: Strict-Transport-Security "max-age=15768000; includeSubdomains",
      xframe_options: X-Frame-Options SAMEORIGIN

    try_files: '$uri $uri/'

    fastcgi_php:
      fastcgi_split_path_info: fastcgi_split_path_info ^(.+\.php)(/.+)$
      fastcgi_pass: 'fastcgi_pass unix:/var/run/php7.0-fpm.sock'
      fastcgi_index: fastcgi_index index.php,
      include_fastcgi: include fastcgi.conf

Example Playbook

Including an example of how to use your role (for instance, with variables passed in as parameters) is always nice for users too:

playbook.yml

- hosts: servers
  roles:
     - { role: ecaepp.nginx }

  vars:

  vhost:
      - server_name: test.com
        listen_port: 80
        root_dir: /var/www/someapp/app/webroot/
        index_name: index.html

        ssl:
          cert_dir: /etc/nginx/ssl
          crt: '/etc/nginx/ssl/someapp.com.crt'
          key: '/etc/nginx/ssl/someapp.com.key'

        security_headers:
          transport_security: Strict-Transport-Security "max-age=15768000;  includeSubdomains",
          xframe_options: X-Frame-Options SAMEORIGIN

        try_files: '$uri $uri/ /index.html'
