Supermarket Belongs to the Community

Supermarket belongs to the community. While Chef has the responsibility to keep it running and be stewards of its functionality, what it does and how it works is driven by the community. The chef/supermarket repository will continue to be where development of the Supermarket application takes place. Come be part of shaping the direction of Supermarket by opening issues and pull requests or by joining us on the Chef Mailing List.

Chef cookbook to install and configure stunnel


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


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/"
default['stunnel']['user'] = "root"
default['stunnel']['group'] = "root"
default['stunnel']['ulimit'] = nil # set to a number to add ulimit setting to init script

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'

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'

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)

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')

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
