Types

type InformerAccess

type InformerAccess interface {
	GetInternalKubernetesInformers() kinternalinformers.SharedInformerFactory
	GetKubernetesInformers() kinformers.SharedInformerFactory

	GetOpenshiftOauthInformers() oauthinformer.SharedInformerFactory
	GetOpenshiftRouteInformers() routeinformer.SharedInformerFactory
	GetOpenshiftUserInformers() userinformer.SharedInformerFactory

	GetInternalOpenshiftAuthorizationInformers() authorizationinformer.SharedInformerFactory
	GetInternalOpenshiftImageInformers() imageinformer.SharedInformerFactory
	GetInternalOpenshiftQuotaInformers() quotainformer.SharedInformerFactory
	GetInternalOpenshiftSecurityInformers() securityinformer.SharedInformerFactory

	Start(stopCh <-chan struct{})
}

func NewInformers

func NewInformers(clientConfig *rest.Config) (InformerAccess, error)

NewInformers is only exposed for the build's integration testing until it can be fixed more appropriately.

type MasterConfig

type MasterConfig struct {
	Options configapi.MasterConfig

	// we phrase it like this so we can build the post-start-hook, but no one can take more indirect dependencies on informers
	InformerStart func(stopCh <-chan struct{})

	// RESTOptionsGetter provides access to storage and RESTOptions for a particular resource
	RESTOptionsGetter restoptions.Getter

	RuleResolver   rbacregistryvalidation.AuthorizationRuleResolver
	SubjectLocator rbacauthorizer.SubjectLocator

	ProjectAuthorizationCache     *projectauth.AuthorizationCache
	ProjectCache                  *projectcache.ProjectCache
	ClusterQuotaMappingController *clusterquotamapping.ClusterQuotaMappingController
	LimitVerifier                 imageadmission.LimitVerifier
	RESTMapper                    *restmapper.DeferredDiscoveryRESTMapper

	// RegistryHostnameRetriever retrieves the name of the integrated registry, or false if no such registry
	// is available.
	RegistryHostnameRetriever registryhostname.RegistryHostnameRetriever

	// PrivilegedLoopbackClientConfig is the client configuration used to call OpenShift APIs from system components
	// To apply different access control to a system component, create a client config specifically for that component.
	PrivilegedLoopbackClientConfig restclient.Config

	// PrivilegedLoopbackKubernetesClientsetExternal is the client used to call Kubernetes APIs from system components,
	// built from KubeClientConfig. It should only be accessed via the *TestingClient() helper methods. To apply
	// different access control to a system component, create a separate client/config specifically for
	// that component.
	PrivilegedLoopbackKubernetesClientsetExternal kclientsetexternal.Interface

	AuditBackend audit.Backend

	// TODO inspect uses to eliminate them
	InternalKubeInformers  kinternalinformers.SharedInformerFactory
	ClientGoKubeInformers  kubeclientgoinformers.SharedInformerFactory
	AuthorizationInformers authorizationinformer.SharedInformerFactory
	RouteInformers         routeinformer.SharedInformerFactory
	QuotaInformers         quotainformer.SharedInformerFactory
	SecurityInformers      securityinformer.SharedInformerFactory
	// contains filtered or unexported fields
}

MasterConfig defines the required parameters for starting the OpenShift master

func BuildMasterConfig

func BuildMasterConfig(
	options configapi.MasterConfig,
	informers InformerAccess,
) (*MasterConfig, error)

BuildMasterConfig builds and returns the OpenShift master configuration based on the provided options

func (*MasterConfig) Run

func (c *MasterConfig) Run(stopCh <-chan struct{}) error

Run launches the OpenShift master by creating a kubernetes master, installing OpenShift APIs into it and then running it. TODO this method only exists to support the old openshift start path. It should be removed a little ways into 3.10.

func (*MasterConfig) RunDNSServer

func (c *MasterConfig) RunDNSServer()

RunDNSServer starts the DNS server

func (*MasterConfig) RunKubeAPIServer

func (c *MasterConfig) RunKubeAPIServer(stopCh <-chan struct{}) error

type TooManyThreadsStuckHealth

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

TooManyThreadsStuckHealth is a health checker that indicates when we have too many thread in a particular method. This condition usually indicates that we got stuck and we should restart ourselves

func NewGRPCStuckThreads

func NewGRPCStuckThreads() *TooManyThreadsStuckHealth

func (*TooManyThreadsStuckHealth) Check

func (h *TooManyThreadsStuckHealth) Check(req *http.Request) error

func (*TooManyThreadsStuckHealth) Count

func (h *TooManyThreadsStuckHealth) Count() int

func (*TooManyThreadsStuckHealth) Name

func (h *TooManyThreadsStuckHealth) Name() string
