NewNodeGroup builds a theoretical node group based on the node definition provided. The node group is not automatically created on the cloud provider side. The node group is not returned by NodeGroups() until it is created.

func (*GceCloudProvider) NodeGroupForNode 

func (gce *GceCloudProvider) NodeGroupForNode(node *apiv1.Node) (cloudprovider.NodeGroup, error)

NodeGroupForNode returns the node group for the given node.

func (gce *GceCloudProvider) NodeGroups() []cloudprovider.NodeGroup

NodeGroups returns all node groups configured for this cloud provider.

func (*GceCloudProvider) Pricing 

func (gce *GceCloudProvider) Pricing() (cloudprovider.PricingModel, errors.AutoscalerError)

Pricing returns pricing model for this cloud provider or error if not available.

func (*GceCloudProvider) Refresh 

func (gce *GceCloudProvider) Refresh() error

Refresh is called before every main loop and can be used to dynamically update cloud provider state. In particular the list of node groups returned by NodeGroups can change as a result of CloudProvider.Refresh().

type GceManager 

type GceManager interface {
	// RegisterMig registers mig in Gce Manager. Returns true if the node group didn't exist before.
	RegisterMig(mig *Mig) bool
	// UnregisterMig unregisters mig in Gce Manager. Returns true if the node group has been removed.
	UnregisterMig(toBeRemoved *Mig) bool
	// GetMigSize gets MIG size.
	GetMigSize(mig *Mig) (int64, error)
	// SetMigSize sets MIG size.
	SetMigSize(mig *Mig, size int64) error
	// DeleteInstances deletes the given instances. All instances must be controlled by the same MIG.
	DeleteInstances(instances []*GceRef) error
	// GetMigForInstance returns MigConfig of the given Instance
	GetMigForInstance(instance *GceRef) (*Mig, error)
	// GetMigNodes returns mig nodes.
	GetMigNodes(mig *Mig) ([]string, error)
	// Refresh updates config by calling GKE API (in GKE mode only).
	Refresh() error
	// GetResourceLimiter returns resource limiter.
	GetResourceLimiter() (*cloudprovider.ResourceLimiter, error)
	// Cleanup cleans up open resources before the cloud provider is destroyed, i.e. go routines etc.
	Cleanup() error
	// contains filtered or unexported methods
}

GceManager handles gce communication and data caching.

func CreateGceManager 

func CreateGceManager(configReader io.Reader, mode GcpCloudProviderMode, clusterName string, discoveryOpts cloudprovider.NodeGroupDiscoveryOptions) (GceManager, error)

CreateGceManager constructs gceManager object.

type GcePriceModel 

type GcePriceModel struct {
}

GcePriceModel implements PriceModel interface for GCE.

func (*GcePriceModel) NodePrice 

func (model *GcePriceModel) NodePrice(node *apiv1.Node, startTime time.Time, endTime time.Time) (float64, error)

NodePrice returns a price of running the given node for a given period of time. All prices are in USD.

func (*GcePriceModel) PodPrice 

func (model *GcePriceModel) PodPrice(pod *apiv1.Pod, startTime time.Time, endTime time.Time) (float64, error)

PodPrice returns a theoretical minimum priece of running a pod for a given period of time on a perfectly matching machine.

type GceRef 

type GceRef struct {
	Project string
	Zone    string

type GcpCloudProviderMode 

type GcpCloudProviderMode string

GcpCloudProviderMode allows to pass information whether the cluster is GCE or GKE.

	ModeGCE GcpCloudProviderMode = "gce"

	// ModeGKE means that the cluster is running
	ModeGKE GcpCloudProviderMode = "gke"

	// ModeGKENAP means that the cluster is running on GKE with autoprovisioning enabled.
	// TODO(maciekpytel): remove this when NAP API is available in normal client
	ModeGKENAP GcpCloudProviderMode = "gke_nap"

type Mig 

type Mig struct {
	GceRef
	// contains filtered or unexported fields

Mig implements NodeGroup interfrace.

func (*Mig) Autoprovisioned 

func (mig *Mig) Autoprovisioned() bool

Autoprovisioned returns true if the node group is autoprovisioned.

func (*Mig) Belongs 

func (mig *Mig) Belongs(node *apiv1.Node) (bool, error)

Debug returns a debug string for the Mig.

func (*Mig) DecreaseTargetSize 

func (mig *Mig) DecreaseTargetSize(delta int) error

DecreaseTargetSize decreases the target size of the node group. This function doesn't permit to delete any existing node and can be used only to reduce the request for new nodes that have not been yet fulfilled. Delta should be negative.

func (*Mig) Delete 

func (mig *Mig) Delete() error

Delete deletes the node group on the cloud provider side. This will be executed only for autoprovisioned node groups, once their size drops to 0.
