func ApplyNamespacedSecret(
	ctx context.Context,
	namespaceClient v1.NamespaceInterface,
	secretClinet v1.SecretInterface,
	config []byte,
) error

Generate a secret resource for the kubeconfig file.

func ExtractKubeconfig

func ExtractKubeconfig(path string, targetContext string) ([]byte, error)

Extract the kubeconfig file for the specified context.

func GenerateConfigFile

func GenerateConfigFile(path string, cluster string) error

Generate a toml file that stores the path and cluster name of the kubeconfig file.

func GeneratePrimaryConfig

func GeneratePrimaryConfig(clientset *kubernetes.Clientset, restConfig *rest.Config) ([]byte, error)

Generate a kubeconfig file for the primary cluster.

func MargeKubeconfig

func MargeKubeconfig(source clientcmdapi.Config, target clientcmdapi.Config) ([]byte, error)

Merge the kubeconfig.

func ReadKubeconfigFromByte

func ReadKubeconfigFromByte(config []byte) (*clientcmdapi.Config, error)

Read the kubeconfig file.

func ReadKubeconfigFromClient

	Path    string
	Cluster string
}

func GetPathAndCluster

func GetPathAndCluster() (Config, error)

Get the path and cluster name from the toml file.
