  +==== Deployment
  +
  +The steps are very similar to the one provided in the java section above, except for the fact that in ruby we are not deploying a jar but the package (`tar.gz`). Assuming a modified version of our stripe plugin was built:
  +
  +[source,bash]
  +----
  +# Copy the tar.gz 
  +> docker cp pkg/killbill-stripe-5.0.0-dev.tar.gz  kb_killbill_1:/tmp
  +
  +# SSH inside the conatainer
  +> docker exec -ti kb_killbill_1 bash
  +
  +# Install the plugin : '/var/lib/killbill/bundles' is the default in our Kill Bill docker images
  +tomcat@6e7d5ae5bfc4> kpm install_ruby_plugin 'dev:stripe' --from-source-file="/tmp/killbill-stripe-5.0.0-dev.tar.gz"  --destination=/var/lib/killbill/bundles
  +
  +# exit
  +tomcat@6e7d5ae5bfc4> ^D
  +
  +# Restart Kill Bill core
  +> docker restart kb_killbill_1

   ==== Examples of Ruby Plugins
   
   We provide a https://github.com/killbill/killbill-hello-world-ruby-plugin[hello world] ruby plugin that can be used as starting point. Make sure to correctly update the `*.gemspec` and the `pom.xml` to correctly reflect the gem name, and maven coordinates of your plugin (if you decide to publish your plugin to Nexus).
  
positive.code: 
  It is recommened to clone some of our existing plugins to get started. For `java`, the https://github.com/killbill/killbill-hello-world-java-plugin[hello world plugin] is a good starting point. For `ruby`, we also provide a https://github.com/killbill/killbill-hello-world-ruby-plugin[hello world plugin]. Depending on the type of plugin to be built, there may be a better example to look at (e.g. look at an existing payment plugin if you are building a new gateway integration).
  
  We provide two plugin frameworks that can be used to implement some of the work that plugins need to do:
  
  * https://github.com/killbill/killbill-plugin-framework-java[`java plugin framework`]
  * https://github.com/killbill/killbill-plugin-framework-ruby[`ruby plugin framework`]
  
negative.code: 
  * What are plugins and what can be achieved through plugins?
  * Where to start the development?
  * Tooling and APIs to build and deploy plugins
