I'm not sure the content of the cr.yaml would work as it is:

• the package is not needed
• I think we also need to set the source code name as the code need to be mounted somewhere now

[lburgazzoli]

maybe we can also name it like cr-example.yaml o something like that just to clarify what the file is for.

[dmvolod]

@lburgazzoli , yes, I agree, but run doesn't work right now for testing due to issue #84 for me
Previously, I ran cr.yaml without issues.

Here an example of the latest spec:

apiVersion: camel.apache.org/v1alpha1
kind: Integration
metadata:
  name: gtest
spec:
  source:
    content: |-
      //
      // To run this integrations use:
      //
      //     kamel run -d camel:groovy runtime/examples/routes.groovy
      //

      rnd = new Random()

      from('timer:groovy?period=1s')
          .routeId('groovy')
          .setBody()
              .constant('Hello Camel K!')
          .process {
              it.in.headers['RandomValue'] = rnd.nextInt()
          }
          .to('log:info?showHeaders=true')
    name: routes.groovy

yeah sorry, got the wrong example!
To run groovy things you also need to define dependencies, something like:

spec:
    dependencies:
    - camel:groovy

@lburgazzoli , thanks, fixed.
