Experimental OpenCrowbar Model

OpenCrowbar Model (image)

Required Overrides

The OpenCrowbar system requires that you overide certain models/controllers for it to work

The required overrides are:

  • Barclamp[Name]::Barclamp

The optional overrides are:

  • Barclamp[Name]::Attrib[SpecialFunction]

Overriding Barclamp.rb

The superclass Barclamp.rb provides everything that you need to operate OpenCrowbar for most functions. You can override it to create advanced functionality.

create_proposal

Notes:

  • superclass calls create_deployment

Use this to pre-populate nodes into a new proposal

is_valid? deployment

Notes:

  • superclass returns true
  • called before deployment.commit
process_inbound_data
transition

This is a critical function, it determines which actions the barclamp takes when it gets new information.

versions

Defaults to 2.0
