Functions

func CreateKubeconfigSecret

func CreateKubeconfigSecret(clientset client.Interface, kubeconfig *clientcmdapi.Config, namespace, name string, dryRun bool) (*api.Secret, error)

func GetClientsetFromSecret

func GetClientsetFromSecret(secret *api.Secret, serverAddress string) (*client.Clientset, error)

func GetServerAddress

func GetServerAddress(c *federationapi.Cluster) (string, error)

func GetVersionedClientForRBACOrFail

func GetVersionedClientForRBACOrFail(hostFactory cmdutil.Factory) (client.Interface, error)

GetVersionedClientForRBACOrFail discovers the versioned rbac APIs and gets the versioned clientset for either the preferred version or the first listed version (if no preference listed) TODO: We need to evaluate the usage of RESTMapper interface to achieve te same functionality

Types

type AdminConfig

type AdminConfig interface {
	// PathOptions provides filesystem based kubeconfig access.
	PathOptions() *clientcmd.PathOptions
	// FedClientSet provides a federation API compliant clientset
	// to communicate with the federation control plane api server
	FederationClientset(context, kubeconfigPath string) (*fedclient.Clientset, error)
	// ClusterFactory provides a mechanism to communicate with the
	// cluster derived from the context and the kubeconfig.
	ClusterFactory(context, kubeconfigPath string) cmdutil.Factory
}

AdminConfig provides a filesystem based kubeconfig (via `PathOptions()`) and a mechanism to talk to the federation host cluster and the federation control plane api server.

func NewAdminConfig

func NewAdminConfig(pathOptions *clientcmd.PathOptions) AdminConfig

NewAdminConfig creates an admin config for `kubefed` commands.

type NoRBACAPIError

type NoRBACAPIError struct {
	// contains filtered or unexported fields
}

used to identify the rbac api availability error.

func (*NoRBACAPIError) Error

func (n *NoRBACAPIError) Error() string

type SubcommandOptions

type SubcommandOptions struct {
	Name                      string
	Host                      string
	FederationSystemNamespace string
	Kubeconfig                string
}

SubcommandOptions holds the configuration required by the subcommands of `kubefed`.

func (*SubcommandOptions) Bind

func (o *SubcommandOptions) Bind(flags *pflag.FlagSet)

func (*SubcommandOptions) SetName

func (o *SubcommandOptions) SetName(cmd *cobra.Command, args []string) error
