Types

type InstanceTypeInfo

type InstanceTypeInfo struct {
	// Storage (ephemeral) available (GiB).
	// Is 0 if not supported or none available.
	Storage int64
	// Max pods per node.
	MaxPodsPerNode int64
	// CPU count.
	CPU int64
}

InstanceTypeInfo holds minimal instance info required to calculate resources to reserve.

func NewInstanceTypeInfo

func NewInstanceTypeInfo(ec2info *ec2.InstanceTypeInfo) InstanceTypeInfo

NewInstanceTypeInfo creates a simple version of ec2.InstanceTypeInfo that provides functions to calculate defaults.

func (InstanceTypeInfo) DefaultCPUToReserve

func (i InstanceTypeInfo) DefaultCPUToReserve() string

DefaultCPUToReserve returns the millicores to reserve.

See https://github.com/awslabs/amazon-eks-ami/blob/ff690788dfaf399e6919eebb59371ee923617df4/files/bootstrap.sh#L183-L208 which takes it form https://cloud.google.com/kubernetes-engine/docs/concepts/cluster-architecture#node_allocatable
