Functions

func EnsureNamespaceServiceAccountRoleBindings 

func EnsureNamespaceServiceAccountRoleBindings(kubeClientInternal kclientsetinternal.Interface, deprecatedOpenshiftClient *osclient.Client, namespace *kapi.Namespace)

EnsureNamespaceServiceAccountRoleBindings initializes roles for service accounts in the namespace

func LegacyStorage 

func LegacyStorage(storage map[schema.GroupVersion]map[string]rest.Storage) map[string]rest.Storage

LegacyStorage returns a storage for locked legacy types.

func NewAssetServerConfigFromMasterConfig 

func NewAssetServerConfigFromMasterConfig(masterConfigOptions configapi.MasterConfig) (*assetapiserver.AssetServerConfig, error)

TODO this is taking a very large config for a small piece of it. The information must be broken up at some point so that we can run this in a pod. This is an indication of leaky abstraction because it spent too much time in openshift start

func NewLeaderElection 

func NewLeaderElection(options configapi.MasterConfig, leader componentconfig.LeaderElectionConfiguration, kc kclientsetexternal.Interface, eventClient v1core.EventInterface) (plug.Plug, func(), error)

NewLeaderElection returns a plug that blocks controller startup until the lease is acquired and a function that will start the process to attain the lease. There are two modes for lease operation - a legacy mode that directly connects to etcd, and the preferred mode which coordinates on a service endpoints object in the kube-system namespace. Because legacy mode and the new mode do not coordinate on the same key, an upgrade must stop all controllers before changing the configuration and starting controllers with the new config.

func NewOAuthServerConfigFromMasterConfig 

func NewOAuthServerConfigFromMasterConfig(masterConfig *MasterConfig) (*oauthapiserver.OAuthServerConfig, error)

TODO this is taking a very large config for a small piece of it. The information must be broken up at some point so that we can run this in a pod. This is an indication of leaky abstraction because it spent too much time in openshift start

func WithPatternPrefixHandler 

func WithPatternPrefixHandler(handler http.Handler, patternHandler http.Handler, prefixes ...string) http.Handler
