CreateResourceLock returns an interface for the resource lock.

Types

type ClientBuilder

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

ClientBuilder can create a variety of kubernetes client interface with its embeded rest.Config.

func NewClientBuilder

func NewClientBuilder(kubeconfig string) (*ClientBuilder, error)

NewClientBuilder returns a *ClientBuilder with the given kubeconfig.

func (*ClientBuilder) APIExtClientOrDie

func (cb *ClientBuilder) APIExtClientOrDie(name string) apiext.Interface

ClientOrDie returns the kubernetes client interface for extended kubernetes objects.

func (*ClientBuilder) ConfigClientOrDie

func (cb *ClientBuilder) ConfigClientOrDie(name string) configclientset.Interface

ClientOrDie returns the kubernetes client interface for security related kubernetes objects such as pod security policy, security context.

func (*ClientBuilder) KubeClientOrDie

func (cb *ClientBuilder) KubeClientOrDie(name string) kubernetes.Interface

ClientOrDie returns the kubernetes client interface for general kubernetes objects.

func (*ClientBuilder) MachineConfigClientOrDie

func (cb *ClientBuilder) MachineConfigClientOrDie(name string) mcfgclientset.Interface

ClientOrDie returns the kubernetes client interface for machine config.

type ControllerContext

type ControllerContext struct {
	ClientBuilder *ClientBuilder

	NamespacedInformerFactory     mcfginformers.SharedInformerFactory
	InformerFactory               mcfginformers.SharedInformerFactory

	AvailableResources map[schema.GroupVersionResource]bool

	Stop <-chan struct{}

	InformersStarted chan struct{}

	KubeInformersStarted chan struct{}

	ResyncPeriod func() time.Duration
}

ControllerContext stores all the informers for a variety of kubernetes objects.

func CreateControllerContext
