Functions

func AddKubeOptionsFlags

func AddKubeOptionsFlags(cmd *cobra.Command, ko *KubeOptions)

AddKubeOptionsFlags sets up the cobra command with the flags from KubeOptions' configFlags so that a kube client can be built to a user's specification. Its one modification is to change the name of the namespace flag to kubecost-namespace because we want to "behave as expected", i.e. --namespace affects the request to the kubecost API, not the request to the k8s API.

func BindAFlagToViperEnv

func BindAFlagToViperEnv(cmd *cobra.Command, v *viper.Viper, flag string)

Binds the flag with viper environment variable and ensures the order of precendence command line > environment variable > default value

Types

type KubeOptions

type KubeOptions struct {
	RestConfig *rest.Config

	// Namespace should be the currently-configured defaultNamespace of the client.
	// This allows e.g. predict to fill in the defaultNamespace if one is not provided
	// in the workload spec.
	DefaultNamespace string

	genericclioptions.IOStreams
	// contains filtered or unexported fields
}
