Types

type AL2 

type AL2 struct {
	DefaultFamily
	*Options
}

func (AL2) DefaultBlockDeviceMappings 

func (a AL2) DefaultBlockDeviceMappings() []*v1alpha1.BlockDeviceMapping

DefaultBlockDeviceMappings returns the default block device mappings for the AMI Family

func (AL2) EphemeralBlockDevice added in v0.11.0 

func (a AL2) EphemeralBlockDevice() *string

func (AL2) SSMAlias 

func (a AL2) SSMAlias(version string, instanceType cloudprovider.InstanceType) string

SSMAlias returns the AMI Alias to query SSM

func (AL2) UserData 

func (a AL2) UserData(kubeletConfig *v1alpha5.KubeletConfiguration, taints []v1.Taint, labels map[string]string, caBundle *string, instanceTypes []cloudprovider.InstanceType, customUserData *string) bootstrap.Bootstrapper

UserData returns the exact same string for equivalent input, even if elements of those inputs are in differing orders, guaranteeing it won't cause spurious hash differences. AL2 userdata also works on Ubuntu

type AMIFamily 

type AMIFamily interface {
	UserData(kubeletConfig *v1alpha5.KubeletConfiguration, taints []core.Taint, labels map[string]string, caBundle *string, instanceTypes []cloudprovider.InstanceType, customUserData *string) bootstrap.Bootstrapper
	SSMAlias(version string, instanceType cloudprovider.InstanceType) string
	DefaultBlockDeviceMappings() []*v1alpha1.BlockDeviceMapping
	DefaultMetadataOptions() *v1alpha1.MetadataOptions
	EphemeralBlockDevice() *string
	FeatureFlags() FeatureFlags
}

AMIFamily can be implemented to override the default logic for generating dynamic launch template parameters

type Bottlerocket struct {
	DefaultFamily
	*Options
}

func (Bottlerocket) DefaultBlockDeviceMappings 

func (b Bottlerocket) DefaultBlockDeviceMappings() []*v1alpha1.BlockDeviceMapping

func (Bottlerocket) UserData 

func (b Bottlerocket) UserData(kubeletConfig *v1alpha5.KubeletConfiguration, taints []v1.Taint, labels map[string]string, caBundle *string, _ []cloudprovider.InstanceType, customUserData *string) bootstrap.Bootstrapper

UserData returns the default userdata script for the AMI Family

type Custom added in v0.14.0 

type Custom struct {
	DefaultFamily
	*Options
}

func (Custom) DefaultBlockDeviceMappings added in v0.14.0 

func (c Custom) DefaultBlockDeviceMappings() []*v1alpha1.BlockDeviceMapping

func (Custom) EphemeralBlockDevice added in v0.14.0 

func (c Custom) EphemeralBlockDevice() *string

EphemeralBlockDevice is the block device that the pods on the node will use. For an AMI of a custom family, this is unknown to us.

func (Custom) SSMAlias added in v0.14.0 

func (c Custom) SSMAlias(version string, instanceType cloudprovider.InstanceType) string

func (Custom) UserData added in v0.14.0 

func (c Custom) UserData(kubeletConfig *v1alpha5.KubeletConfiguration, taints []v1.Taint, labels map[string]string, caBundle *string, _ []cloudprovider.InstanceType, customUserData *string) bootstrap.Bootstrapper

UserData returns the default userdata script for the AMI Family

type DefaultFamily added in v0.17.0 

type DefaultFamily struct{}

DefaultFamily provides default values for AMIFamilies that compose it

func (DefaultFamily) FeatureFlags added in v0.17.0 

func (d DefaultFamily) FeatureFlags() FeatureFlags

type FeatureFlags added in v0.17.0 

type FeatureFlags struct {
	UsesENILimitedMemoryOverhead bool
	PodsPerCoreEnabled           bool
	EvictionSoftEnabled          bool
}

FeatureFlags describes whether the features below are enabled for a given AMIFamily

type LaunchTemplate
