Functions

func BuildKubemark

func BuildKubemark(opts config.AutoscalingOptions, do cloudprovider.NodeGroupDiscoveryOptions, rl *cloudprovider.ResourceLimiter) cloudprovider.CloudProvider

BuildKubemark builds Kubemark cloud provider.

Types

type KubemarkCloudProvider

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

KubemarkCloudProvider implements CloudProvider interface for kubemark

func BuildKubemarkCloudProvider

func BuildKubemarkCloudProvider(kubemarkController *kubemark.KubemarkController, specs []string, resourceLimiter *cloudprovider.ResourceLimiter) (*KubemarkCloudProvider, error)

BuildKubemarkCloudProvider builds a CloudProvider for kubemark. Builds node groups from passed in specs.

func (*KubemarkCloudProvider) Cleanup

func (kubemark *KubemarkCloudProvider) Cleanup() error

Cleanup cleans up all resources before the cloud provider is removed

func (*KubemarkCloudProvider) GPULabel

func (kubemark *KubemarkCloudProvider) GPULabel() string

GPULabel returns the label added to nodes with GPU resource.

func (*KubemarkCloudProvider) GetAvailableGPUTypes

func (kubemark *KubemarkCloudProvider) GetAvailableGPUTypes() map[string]struct{}

GetAvailableGPUTypes return all available GPU types cloud provider supports

func (*KubemarkCloudProvider) GetAvailableMachineTypes

func (kubemark *KubemarkCloudProvider) GetAvailableMachineTypes() ([]string, error)

GetAvailableMachineTypes get all machine types that can be requested from the cloud provider. Implementation optional.

func (*KubemarkCloudProvider) GetNodeGpuConfig

func (kubemark *KubemarkCloudProvider) GetNodeGpuConfig(node *apiv1.Node) *cloudprovider.GpuConfig

GetNodeGpuConfig returns the label, type and resource name for the GPU added to node. If node doesn't have any GPUs, it returns nil.

func (*KubemarkCloudProvider) GetResourceLimiter

func (kubemark *KubemarkCloudProvider) GetResourceLimiter() (*cloudprovider.ResourceLimiter, error)

GetResourceLimiter returns struct containing limits (max, min) for resources (cores, memory etc.).

func (*KubemarkCloudProvider) HasInstance

func (kubemark *KubemarkCloudProvider) HasInstance(node *apiv1.Node) (bool, error)

HasInstance returns whether a given node has a corresponding instance in this cloud provider

func (*KubemarkCloudProvider) Name

func (kubemark *KubemarkCloudProvider) Name() string

Name returns name of the cloud provider.

func (*KubemarkCloudProvider) NewNodeGroup

func (kubemark *KubemarkCloudProvider) NewNodeGroup(machineType string, labels map[string]string, systemLabels map[string]string,
	taints []apiv1.Taint,
	extraResources map[string]resource.Quantity) (cloudprovider.NodeGroup, error)

NewNodeGroup builds a theoretical node group based on the node definition provided.

func (*KubemarkCloudProvider) NodeGroupForNode

func (kubemark *KubemarkCloudProvider) NodeGroupForNode(node *apiv1.Node) (cloudprovider.NodeGroup, error)

NodeGroupForNode returns the node group for the given node.

func (*KubemarkCloudProvider) NodeGroups

func (kubemark *KubemarkCloudProvider) NodeGroups() []cloudprovider.NodeGroup

NodeGroups returns all node groups configured for this cloud provider.

func (*KubemarkCloudProvider) Pricing

func (kubemark *KubemarkCloudProvider) Pricing() (cloudprovider.PricingModel, errors.AutoscalerError)

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

func (*KubemarkCloudProvider) Refresh

func (kubemark *KubemarkCloudProvider) 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 NodeGroup

type NodeGroup struct {
	Name string
	// contains filtered or unexported fields
}

NodeGroup implements NodeGroup interface.

func (*NodeGroup) AtomicIncreaseSize

func (nodeGroup *NodeGroup) AtomicIncreaseSize(delta int) error

AtomicIncreaseSize is not implemented.

func (*NodeGroup) Autoprovisioned

func (nodeGroup *NodeGroup) Autoprovisioned() bool

Autoprovisioned returns true if the node group is autoprovisioned.

func (*NodeGroup) Create

func (nodeGroup *NodeGroup) Create() (cloudprovider.NodeGroup, error)

Create creates the node group on the cloud provider side.

func (*NodeGroup) Debug

func (nodeGroup *NodeGroup) Debug() string

Debug returns a debug string for the nodegroup.

func (*NodeGroup) DecreaseTargetSize

func (nodeGroup *NodeGroup) 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 (*NodeGroup) Delete

func (nodeGroup *NodeGroup) Delete() error

Delete deletes the node group on the cloud provider side.

func (*NodeGroup) DeleteNodes

func (nodeGroup *NodeGroup) DeleteNodes(nodes []*apiv1.Node) error

DeleteNodes deletes the specified nodes from the node group.

func (*NodeGroup) Exist

func (nodeGroup *NodeGroup) Exist() bool

Exist checks if the node group really exists on the cloud provider side.

func (*NodeGroup) ForceDeleteNodes

func (nodeGroup *NodeGroup) ForceDeleteNodes(nodes []*apiv1.Node) error

ForceDeleteNodes deletes nodes from the group regardless of constraints.

func (*NodeGroup) GetOptions

func (nodeGroup *NodeGroup) GetOptions(defaults config.NodeGroupAutoscalingOptions) (*config.NodeGroupAutoscalingOptions, error)

GetOptions returns NodeGroupAutoscalingOptions that should be used for this particular NodeGroup. Returning a nil will result in using default options.

func (*NodeGroup) Id

func (nodeGroup *NodeGroup) Id() string
