Functions

func BuildRemoteCfg

func BuildRemoteCfg(
	remoteCluster *api.Cluster,
	remoteCtx *api.Context,
	clusterName, token string,
) api.Config

func SecretObjMeta

func SecretObjMeta(namespace string, cluster string) metav1.ObjectMeta

func SecretToConfig

func SecretToConfig(secret *kubev1.Secret) (clusterName string, config clientcmd.ClientConfig, err error)

SecretToConfig extracts the cluster name and *Config from a KubeConfig secret. If the provided secret is not a KubeConfig secret, an error is returned.

func ToSecret

func ToSecret(namespace string, cluster string, kc api.Config) (*kubev1.Secret, error)

ToSecret converts a kubernetes api.Config to a secret with the provided name and namespace.

Types

type KubeLoader

type KubeLoader interface {

	GetRawConfigForContext(path, context string) (clientcmdapi.Config, error)
	GetClientConfigForContext(path, context string) (clientcmd.ClientConfig, error)
	GetRestConfigFromBytes(config []byte) (*rest.Config, error)
}

func NewKubeLoader

func NewKubeLoader(timeout time.Duration) KubeLoader

default KubeLoader
