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
