nginx_conf

Use the nginx_conf Chef InSpec resource to test configuration data for the NGINX server located at /etc/nginx/nginx.conf on Linux and Unix platforms.

Stability: Experimental

Availability

Installation

This resource is distributed along with Chef InSpec itself. You can use it automatically.

Version

This resource first became available in v1.37.6 of InSpec.

Syntax

An nginx_conf resource block declares the client NGINX configuration data to be tested:

describe nginx_conf.params['pid'] do
  it { should cmp 'logs/nginx.pid' }
end

where

nginx_conf is the resource to reference your NGINX configuration
params accesses all its parameters
params['pid'] selects the pid entry from the global NGINX configuration
{ should cmp 'logs/nginx.pid' } tests if the PID is set to logs/nginx.pid (via cmp matcher)

Examples

The following examples show how to use this Chef InSpec audit resource.

Find a specific server

servers = nginx_conf.servers
domain2 = servers.find { |s| s.params['server_name'].flatten.include? 'domain2.com' }
describe 'No server serves domain2' do
  subject { domain2 }
  it { should be_nil }
end

Test a raw parameter

describe nginx_conf.params['worker_processes'].flatten do
  it { should cmp 5 }
end

Matchers

For a full list of available matchers, please visit our matchers page.

http

Retrieves all http entries in the configuration file.

nginx_conf.http
=> nginx_conf /etc/nginx/nginx.conf, http entries

It provides further access to all individual entries, servers, and locations.

nginx_conf.http.entries
=> [nginx_conf /etc/nginx/nginx.conf, http entry ...]

nginx_conf.http.servers
=> [nginx_conf /etc/nginx/nginx.conf, server entry ...]

nginx_conf.http.locations
=> [nginx_conf /etc/nginx/nginx.conf, location entry ...]

You can access each of these from the array and inspect it further (see below).

servers

Retrieve all servers entries in the configuration:

# all servers across all configs aggregated:
nginx_conf.servers
=> [nginx_conf /etc/nginx/nginx.conf, server entry ...]

# servers that belong to a specific http entry:
nginx_conf.http.entries[0].servers
=> [nginx_conf /etc/nginx/nginx.conf, server entry ...]

Servers provide access to all their locations, parent http entry, and raw parameters:

server = nginx_conf.servers[0]

server.locations
=> [nginx_conf /etc/nginx/nginx.conf, location entry ...]

server.parent
=> nginx_conf /etc/nginx/nginx.conf, http entry

server.params
=> {"listen"=>[["85"]],
   "server_name"=>[["domain1.com", "www.domain1.com"]],
   "root"=>[["html"]],
   "location"=>[{"_"=>["~", "\\.php$"], "fastcgi_pass"=>[["127.0.0.1:1025"]]}]}

locations

Retrieve all location entries in the configuration:

# all locations across all configs aggregated:
nginx_conf.locations
=> [nginx_conf /etc/nginx/nginx.conf, location entry ...]

# locations of a http entry aggregated:
nginx_conf.http.entries[0].locations
=> [nginx_conf /etc/nginx/nginx.conf, location entry ...]

# locations of a specific server:
nginx_conf.servers[0].locations
=> [nginx_conf /etc/nginx/nginx.conf, location entry ...]

Locations provide access to their parent server entry and raw parameters:

location = nginx_conf.locations[0]

location.parent
=> nginx_conf /etc/nginx/nginx.conf, server entry

location.params
=> {"_"=>["~", "\\.php$"], "fastcgi_pass"=>[["127.0.0.1:1025"]]}

configuration file path

If the NGINX configuration file is not located at the default path, /etc/nginx/nginx.conf, the path can specified as the first parameter of the describe block:

describe nginx_conf('/opt/nginx/nginx.conf').params['pid'] do
  it { should cmp 'logs/nginx.pid' }
end
