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

Important Note
It turns out that creating a valid ruby file from Chef attributes is trickier than I originally thought. Attributes can be added to the node object via JSON strings (node attributes or environment/role in JSON form) or Ruby methods (wrapper cookbooks or the ruby version of environments/roles). There is a library file called helpers.rb
which includes the typecast
method which is used in the lita_config.rb.erb
template to build out valid ruby configuration.
This method is new and I've tested it with contrived data. However, if you find a situation that doesn't work, you can can create a wrapper cookbook and set the config_cookbook
and config_template
attributes to your own template. Then be sure to notify me through GitHub issues and I'll attempt to adjust the method to support whatever case I missed.
Usage
lita::default
Installs and configures the lita chatbot.
Configuration
Adapter
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 bin/lita
Adapter Configuration
The adapter config now supports complex ruby data types (i.e. hashes, hash of arrays, etc.)
Plugins
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"] = [ "ping", { "jenkins" => ">= 0.0.1" } { "foo" => ">= 1.2.3, :git => 'git://github.com/foo/foo.git'" } { "bar" => ":path => '/path/to/local/plugin/lita-bar'" } ]
The above example has four different ways to install / manage plugins:
- the latest version of the
lita-ping
plugin from rubygems.org - the version greater than
0.0.1
oflita-jenkins
plugin from rubygems.org - the repository for foo-lita from git want having version greater than or equal to
1.2.3
(This could be public or private depending on whether the node/user has access to git.) - A local plugin called 'lita-bar' on the filesystem of the lita node found at the path
/path/to/local/plugin/lita-bar
Plugin Configuration
The plugins can also be configured with complex data types in ruby or json:
default["lita"]["plugin_config"] = { "foo" => { "bar" => { "key1" => "val1" } } }
{ "lita": { "plugin_config": { "foo": { "bar": { "key1": "val1" } } } } }
It can even take a string that looks like a hash and convert it appropriately:
{ "lita": { "plugin_config": { "foo": "{ \"bar\": { \"key1\": \"val1\" } }" } } }
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"]["redis_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.
Example
Here's an example node configuration for leveraging lita-hipchat
:
{ "lita": { "adapters": ["hipchat"], "adapter_config": { "hipchat": { "jid": "99999_0000000@chat.hipchat.com", "password": "sekret1", "rooms": ":all", "muc_domain": "conf.hipchat.com" } }, "gems": { "pagerduty-sdk", ":git => \"https://github.com/kryptek/pagerduty-sdk.git\"" }, "plugins": [ "jenkins", "pagerduty", "cron", "dig", "youtube", "xkcd", "jenkins", "wikipedia" ], "plugin_config": { "jenkins": { "url": "http://jenkins.notreally.com/", "auth": "lita:sekret1" }, "pagerduty": { "api_key": "kkkkkkkkkkkkkkkkkkkkkk", "subdomain": "notreally" } } }

Contingent cookbooks
There are no cookbooks that are contingent upon this one.
v0.1.1 (2014-12-19)
- [#13] - typo in README.md
- [#14] - make test kitchen work with serverspec ver > 2
v0.1.0 (2014-12-02)
- [#10] - Breaking change. Supports new config.adapters for Lita v4+. Older versions of Lita will likely not work anymore.
- Changed these attribute names and class types to make them plural. ["lita"]["adapters"] and ["lita"]["adapter_versions"]
v0.0.4 (2014-09-29)
- [#3] - Runs bundler as the daemon user but also does some backflips to try to ensure a little degree of security
- [#5] - Using su instead of sudo and writes out console output to daemon.log
- [#6] - Full embracing of the hack to try to and rubyify strings and/or normal ruby attributes into the ruby config
- Added the exit code in the init script but I don't think it helps alot. I think most failures happen after lita has backgrounded itself.
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
