var InClusterConfig func() (*rest.Config, error) = func() (*rest.Config, error) {
	return rest.InClusterConfig()
}

InClusterConfig defines a function for checking if this code is executing in kubernetes. This can be overriden if needed.

Functions

func CreateScheme

func CreateScheme() *apiruntime.Scheme

func NewKubeHTTPClient

func NewKubeHTTPClient() (Kube, client.Client, error)

type KubeHTTP

type KubeHTTP struct {
	Client      client.Client
	ClusterName string
	DynClient   dynamic.Interface
