func LoadExecCredential(data []byte) (runtime.Object, *rest.Config, error)
LoadExecCredential loads the configuration needed for an exec plugin to communicate with a cluster.
LoadExecCredential expects the provided data to be a serialized client.authentication.k8s.io ExecCredential object (of any version). If the provided data is invalid (i.e., it cannot be unmarshalled into any known client.authentication.k8s.io ExecCredential version), an error will be returned. A successfully unmarshalled ExecCredential will be returned as the first return value.
If the provided data is successfully unmarshalled, but it does not contain cluster information (i.e., ExecCredential.Spec.Cluster == nil), then an error will be returned.
Note that the returned rest.Config will use anonymous authentication, since the exec plugin has not returned credentials for this cluster yet.
func LoadExecCredentialFromEnv() (runtime.Object, *rest.Config, error)
LoadExecCredentialFromEnv is a helper-wrapper around LoadExecCredential that loads from the well-known KUBERNETES_EXEC_INFO environment variable.
When the KUBERNETES_EXEC_INFO environment variable is not set or is empty, then this function will immediately return an error.
