Overview

This version of Photon cloud provider supports the disk interface for Photon persistent disk volume plugin. LoadBalancer, Routes, and Zones are currently not supported. The use of Photon cloud provider requires to start kubelet, kube-apiserver, and kube-controller-manager with config flag: '--cloud-provider=photon --cloud-config=[path_to_config_file]'. When running multi-node kubernetes using docker, the config file should be located inside /etc/kubernetes.

Types

type Disks 

type Disks interface {
	// AttachDisk attaches given disk to given node. Current node
	// is used when nodeName is empty string.
	AttachDisk(ctx context.Context, pdID string, nodeName k8stypes.NodeName) error

	// DetachDisk detaches given disk to given node. Current node
	// is used when nodeName is empty string.
	DetachDisk(ctx context.Context, pdID string, nodeName k8stypes.NodeName) error

	// DiskIsAttached checks if a disk is attached to the given node.
	DiskIsAttached(ctx context.Context, pdID string, nodeName k8stypes.NodeName) (bool, error)

	// DisksAreAttached is a batch function to check if a list of disks are attached
	// to the node with the specified NodeName.
	DisksAreAttached(ctx context.Context, pdIDs []string, nodeName k8stypes.NodeName) (map[string]bool, error)

	// CreateDisk creates a new PD with given properties.
	CreateDisk(volumeOptions *VolumeOptions) (pdID string, err error)

	// DeleteDisk deletes PD.
	DeleteDisk(pdID string) error
}

Disks is interface for manipulation with PhotonController Persistent Disks.

func (*PCCloud) DiskIsAttached 

func (pc *PCCloud) DiskIsAttached(ctx context.Context, pdID string, nodeName k8stypes.NodeName) (bool, error)

DiskIsAttached returns if disk is attached to the VM using controllers supported by the plugin.

func (*PCCloud) DisksAreAttached 

func (pc *PCCloud) DisksAreAttached(ctx context.Context, pdIDs []string, nodeName k8stypes.NodeName) (map[string]bool, error)

DisksAreAttached returns if disks are attached to the VM using controllers supported by the plugin.

func (*PCCloud) GetZone 

func (pc *PCCloud) GetZone(ctx context.Context) (cloudprovider.Zone, error)

func (*PCCloud) GetZoneByNodeName 

func (pc *PCCloud) GetZoneByNodeName(ctx context.Context, nodeName k8stypes.NodeName) (cloudprovider.Zone, error)

GetZoneByNodeName implements Zones.GetZoneByNodeName This is particularly useful in external cloud providers where the kubelet does not initialize node data.

func (*PCCloud) GetZoneByProviderID 

func (pc *PCCloud) GetZoneByProviderID(ctx context.Context, providerID string) (cloudprovider.Zone, error)

GetZoneByProviderID implements Zones.GetZoneByProviderID This is particularly useful in external cloud providers where the kubelet does not initialize node data.

func (*PCCloud) HasClusterID 

func (pc *PCCloud) HasClusterID() bool

HasClusterID returns true if the cluster has a clusterID

func (*PCCloud) Initialize 

func (pc *PCCloud) Initialize(clientBuilder cloudprovider.ControllerClientBuilder, stop <-chan struct{})

func (*PCCloud) InstanceExistsByProviderID 

func (pc *PCCloud) InstanceExistsByProviderID(ctx context.Context, providerID string) (bool, error)

InstanceExistsByProviderID returns true if the instance with the given provider id still exists and is running. If false is returned with no error, the instance will be immediately deleted by the cloud controller manager.

func (*PCCloud) InstanceID
