Functions

func GetHollowKubeletConfig

func GetHollowKubeletConfig(opt *HollowKubeletOptions) (*options.KubeletFlags, *kubeletconfig.KubeletConfiguration)

Builds a KubeletConfiguration for the HollowKubelet, ensuring that the usual defaults are applied for fields we do not override.

Types

type HollowKubelet

type HollowKubelet struct {
	KubeletFlags         *options.KubeletFlags
	KubeletConfiguration *kubeletconfig.KubeletConfiguration
	KubeletDeps          *kubelet.Dependencies
}

func NewHollowKubelet

func NewHollowKubelet(
	flags *options.KubeletFlags,
	config *kubeletconfig.KubeletConfiguration,
	client *clientset.Clientset,
	heartbeatClient *clientset.Clientset,
	cadvisorInterface cadvisor.Interface,
	imageService internalapi.ImageManagerService,
	runtimeService internalapi.RuntimeService,
	containerManager cm.ContainerManager) *HollowKubelet

func (*HollowKubelet) Run

func (hk *HollowKubelet) Run()

Starts this HollowKubelet and blocks.

type HollowKubeletOptions

type HollowKubeletOptions struct {
	NodeName            string
	KubeletPort         int
	KubeletReadOnlyPort int
	MaxPods             int
	PodsPerCore         int
	NodeLabels          map[string]string
	RegisterWithTaints  []v1.Taint
}

HollowKubeletOptions contains settable parameters for hollow kubelet.

type KubemarkController

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

KubemarkController is a simplified version of cloud provider for kubemark. It allows to add and delete nodes from a kubemark cluster and introduces nodegroups by applying labels to the kubemark's hollow-nodes.

func NewKubemarkController

func NewKubemarkController(externalClient kubeclient.Interface, externalInformerFactory informers.SharedInformerFactory,
	kubemarkClient kubeclient.Interface, kubemarkNodeInformer informersv1.NodeInformer) (*KubemarkController, error)

NewKubemarkController creates KubemarkController using the provided clients to talk to external and kubemark clusters.

func (*KubemarkController) GetNodeGroupForNode

func (kubemarkController *KubemarkController) GetNodeGroupForNode(node string) (string, error)

GetNodeGroupForNode returns the name of the node group to which the node belongs.

func (*KubemarkController) GetNodeGroupSize

func (kubemarkController *KubemarkController) GetNodeGroupSize(nodeGroup string) (int, error)

GetNodeGroupSize returns the current size for the node group as observed.

func (*KubemarkController) GetNodeGroupTargetSize

func (kubemarkController *KubemarkController) GetNodeGroupTargetSize(nodeGroup string) (int, error)

GetNodeGroupTargetSize returns the size of the node group as a sum of current observed size and number of upcoming nodes.

func (*KubemarkController) GetNodeNamesForNodeGroup

func (kubemarkController *KubemarkController) GetNodeNamesForNodeGroup(nodeGroup string) ([]string, error)

GetNodeNamesForNodeGroup returns list of the nodes in the node group.

func (*KubemarkController) RemoveNodeFromNodeGroup

func (kubemarkController *KubemarkController) RemoveNodeFromNodeGroup(nodeGroup string, node string) error

func (*KubemarkController) Run

func (kubemarkController *KubemarkController) Run(stopCh chan struct{})

Run populates the node template needed for creation of kubemark nodes and starts the worker routine for creating new nodes.

func (*KubemarkController) SetNodeGroupSize

func (kubemarkController *KubemarkController) SetNodeGroupSize(nodeGroup string, size int) error

SetNodeGroupSize changes the size of node group by adding or removing nodes.

func (*KubemarkController) WaitForCacheSync

func (kubemarkController *KubemarkController) WaitForCacheSync(stopCh chan struct{}) bool

WaitForCacheSync waits until all caches in the controller are populated.
