Kubernetes Client

Constant Summary collapse

ENTITY_TYPES =

Dynamically creating classes definitions (class Pod, class Service, etc.), The classes are extending RecursiveOpenStruct. This cancels the need to define the classes manually on every new entity addition, and especially since currently the class body is empty

%w(Pod Service ReplicationController Node Event Endpoint
                  Namespace).map do |et|
  clazz = Class.new(RecursiveOpenStruct) do
    def initialize(hash = nil, args = {})
      args.merge!(recurse_over_arrays: true)
      super(hash, args)
    end
  end
  [Kubeclient.const_set(et, clazz), et]
