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 

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 AMI 

type AMI struct {
	AmiID        string
	CreationDate string
}

type AMIFamily 

type AMIFamily interface {
	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

func (Bottlerocket) SSMAlias 

func (b Bottlerocket) SSMAlias(version string, instanceType *cloudprovider.InstanceType) string

SSMAlias returns the AMI Alias to query SSM

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 

type Custom struct {
	DefaultFamily
	*Options
}

func (Custom) DefaultBlockDeviceMappings 

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

func (Custom) EphemeralBlockDevice 

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 

func (c Custom) SSMAlias(_ string, _ *cloudprovider.InstanceType) string

func (Custom) UserData 

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

UserData returns the default userdata script for the AMI Family

type DefaultFamily 

type DefaultFamily struct{}

DefaultFamily provides default values for AMIFamilies that compose it

func (DefaultFamily) FeatureFlags 

func (d DefaultFamily) FeatureFlags() FeatureFlags

type FeatureFlags 

type FeatureFlags struct {
	UsesENILimitedMemoryOverhead bool
	PodsPerCoreEnabled           bool
	EvictionSoftEnabled          bool
}

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

type LaunchTemplate 

type LaunchTemplate struct {
	*Options
	UserData            bootstrap.Bootstrapper
	BlockDeviceMappings []*v1alpha1.BlockDeviceMapping
	MetadataOptions     *v1alpha1.MetadataOptions
	AMIID               string
	InstanceTypes       []*cloudprovider.InstanceType `hash:"ignore"`
	DetailedMonitoring  bool
}

LaunchTemplate holds the dynamically generated launch template parameters

type Options 

type Options struct {
	ClusterName             string
	ClusterEndpoint         string
	AWSENILimitedPodDensity bool
	InstanceProfile         string
	CABundle                *string `hash:"ignore"`
	// Level-triggered fields that may change out of sync.
	SecurityGroupsIDs []string
	Tags              map[string]string
	Labels            map[string]string `hash:"ignore"`
