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.

Installs and configures the lita chatbot.

Supported Platforms

  • Ubuntu
    • 12.04 (precise)
    • 14.04 (precise)

It will likely work on other Ubuntu versions, however the automatic methods of installing ruby and redis will have issues.

Tunable Attributes

All tunable attributes are in the lita heirarchy.

Important Note

Many of the configuration elements (particularly in adapter or plugins) require symbols instead of strings. Since:

  • The cookbook is using Chef templates (ERB) to generate more ruby AND
  • ERB calls to_s on variables in the template
  • Even if I try to do var.inspect on the ERB variable, I can't handle those who pass their attributes via JSON (i.e. environment, role, or node)

you'll need to put your items that should be symbols in as strings For example:

default["lita"]["adapter"] = ":shell"

For the adapter and plugin config the template will try to detect strings that begin with : and not quote them in the lita_config.rb.



Installs and configures the lita chatbot.



To make this effective you'll need to choose a non-default adapter from the Lita plugin page. The :shell adapter will not startup in daemon mode so the only way to test with it is to spin up a node, change into the node["lita"]["install_dir"] and run lita

Adapter Configuration

The adapter config is simply key/value pairs. If you need more complicated ruby configuratino (as some adapters do) you'll likely want to create a wrapper cookbook and set the config_cookbook and config_template attributes to your own template.


Plugins can be listed in an array or, optionally listed as an array of hashes using plugin name as the key and Gemfile line syntax:

default["lita"]["plugins"] = [
  { "jenkins" => ">= 0.0.1" }
  { "foo" => ">= 1.2.3, :git => 'git://'" }

Plugin Configuration

The plugins can be configured with a hash of hashes that are keyed off the plugin name:

default["lita"]["plugin_config"] = {
  "jenkins" => {
    "url" => ""
    "auth" => "user1:sekret"

Ruby and Redis

Lita requires recent versions of Ruby and Redis. By default, the lita cookbook will automatically try to find appropriate ruyb and redis versions for your platform and version.

To install those dependencies yourself, simple set the install type attributes to none as such:

node.default["lita"]["ruby_install_type"] = "none"
node.default["lita"]["redit_install_type"] = "none"

If these versions don't work for you (or the cookbook doesn't currently support your platform/version), you can manage the installation of ruby and redis yourself through various methods:

  • Add ruby and redis using community cookbooks in your node/role run_list
  • Creating a wrapper cookbook that does the same
  • Using a base image that already includes the dependencies

The only requirement for the lita cookbook is that ruby, gem and bundler are in the system path and provide the appropriate versions to work with lita.


Here's an example node configuration for leveraging lita-hipchat:

  "lita": {
    "adapter": "hipchat",
    "adapter_config": {
      "jid": "",
      "password": "sekret1",
      "rooms": ":all",
      "muc_domain": ""
    "gems": {
      "pagerduty-sdk", ":git => \"\""
    "plugins": [
    "plugin_config": {
      "jenkins": {
        "url": "",
        "auth": "lita:sekret1"
      "pagerduty": {
        "api_key": "kkkkkkkkkkkkkkkkkkkkkk",
        "subdomain": "notreally"

lita Cookbook Changelog

v0.0.3 (2014-08-12)

  • Added the rest of the standard Lita attributes (mention name and http properties) (issue #2)
  • Added new "gems" attribute to add in custom gem setups. This allowed me to remove the pagerduty-sdk logic in the Gemfile.erb
  • Turned the package installation into an attribute so native packages can be added as needed by adapter or handlers
  • Fixed single/double quote stuff in the recipe. I'm not very consistent with that stuff

v0.0.2 (2014-07-23)

  • Initial version
