chef-stunnel's Introduction

stunnel

Build Status

Chef cookbook to install and configure stunnel

Resources

An stunnel_connection resource is provided for defining stunnel connections. As a client:

include_recipe 'stunnel'

stunnel_connection 'random_service' do
  connect "#{rnd_srv_node['ipaddress']}:#{rnd_srv_node['random_service']['port']}"
  accept node['random_service']['local_accept_port']
  notifies :restart, 'service[stunnel]'
end

As a server:

include_recipe 'stunnel::server'

stunnel_connection 'random_service' do
  accept node['random_service']['tunnel_port']
  connect node['random_service']['port']
  notifies :restart, 'service[stunnel]'
end

Attributes

Lots of configurable attributes:

default['stunnel']['install_method'] = 'package'  # the other valid option is 'source'

default['stunnel']['packages'] = %w(stunnel4)
default['stunnel']['service_name'] = 'stunnel4'

default['stunnel']['ssl_dir'] = '/etc/ssl'
default['stunnel']['server_ssl_req']  = "/C=US/ST=Several/L=Locality/O=Example/OU=Operations/CN=#{node['fqdn']}/emailAddress=root@#{node['fqdn']}"
default['stunnel']['cert_fqdn'] = node['fqdn']

default['stunnel']['use_chroot'] = false
default['stunnel']['chroot_path'] = "/usr/var/lib/stunnel"
default['stunnel']['pidfile'] = "/tmp/stunnel.pid"
default['stunnel']['user'] = "root"
default['stunnel']['group'] = "root"

default['stunnel']['https']['enabled'] = false
default['stunnel']['https']['accept_port'] = "443"
default['stunnel']['https']['connect_port'] = "81"

default['stunnel']['client_mode'] = true

default['stunnel']['ssl_version'] = 'all'
default['stunnel']['ssl_options'] = 'NO_SSLv2'
default['stunnel']['socket_tunings'] = %w(l:TCP_NODELAY=1 r:TCP_NODELAY=1)
default['stunnel']['compression'] = nil # zlib
default['stunnel']['debug'] = nil # 3
default['stunnel']['output'] = '/var/log/stunnel.log'

# key value pair mapping for default var file
default['stunnel']['default']['enabled'] = 1
default['stunnel']['default']['files'] = '/etc/stunnel/*.conf'
default['stunnel']['default']['options'] = ''

ChefSpec Matchers

A set of ChefSpec matchers is included for unit testing with ChefSpec. These are automatically available when you make this cookbook a dependency in your cookbook's metadata. To illustrate:

Recipe code:

stunnel_connection 'haproxy_ssl' do
  accept    '443'
  connect   '8443'
end

And the matching spec:

it 'should create stunnel_connection haproxy_ssl' do
  expect(chef_run).to create_stunnel_connection('haproxy_ssl').with(
    accept:  '443',
    connect: '8443'
  )
end

You can also make assertions for notifying other resources:

it 'should notify stunnel to restart on changes to stunnel_connection[haproxy_ssl]' do
  resource = chef_run.stunnel_connection('haproxy_ssl')
  expect(resource).to notify('service[stunnel]').to(:restart)
end

A matcher for the delete action is also available:

it 'should delete stunnel_connection haproxy_ssl' do
  expect(chef_run).to delete_stunnel_connection('haproxy_ssl')
end

Testing Locally

To run the tests, make sure you've got the latest ChefDK along with Vagrant then you can run chef exec kitchen test which will run the entire test suite on all platforms.

If you want to speed things up, install the vagrant-cachier gem by doing the following: vagrant plugin install vagrant-cachier
