Types

type AMIReleaseVersion

type AMIReleaseVersion struct {
	Version semver.Version
	Date    string
}

func ParseReleaseVersion

func ParseReleaseVersion(releaseVersion string) (AMIReleaseVersion, error)

ParseReleaseVersion parses an AMI release version string that's in the format `1.18.8-20201007`

func (AMIReleaseVersion) Compare

func (a AMIReleaseVersion) Compare(b AMIReleaseVersion) int

Compare returns 0 if a==b, -1 if a < b, and +1 if a > b.

func (AMIReleaseVersion) GTE

func (a AMIReleaseVersion) GTE(b AMIReleaseVersion) bool

GTE checks if a is greater than or equal to b.

func (AMIReleaseVersion) LTE

func (a AMIReleaseVersion) LTE(b AMIReleaseVersion) bool

LTE checks if a is less than or equal to b.

type CreateOpts

type CreateOpts struct {
	UpdateAuthConfigMap       bool
	InstallNeuronDevicePlugin bool
	InstallNvidiaDevicePlugin bool
	DryRun                    bool
	SkipOutdatedAddonsCheck   bool
	ConfigFileProvided        bool
}

CreateOpts controls specific steps of node group creation

type DrainInput

	Undo                  bool
	DisableEviction       bool
	Parallel              int
}

type Manager

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

func New

func New(cfg *api.ClusterConfig, ctl *eks.ClusterProvider, clientSet kubernetes.Interface, instanceSelector eks.InstanceSelector) *Manager

New creates a new manager.

func (*Manager) Create

func (m *Manager) Create(ctx context.Context, options CreateOpts, nodegroupFilter filter.NodegroupFilter) error

Create creates a new nodegroup with the given options.

func (*Manager) Delete

func (m *Manager) Delete(ctx context.Context, nodeGroups []*api.NodeGroup, managedNodeGroups []*api.ManagedNodeGroup, wait, plan bool) error

func (*Manager) Drain

	NodeInstanceRoleARN  string
	AutoScalingGroupName string
	Version              string
	NodeGroupType        api.NodeGroupType `json:"Type"`
}

Summary represents a summary of a nodegroup stack

type UpgradeOptions

type UpgradeOptions struct {
	// NodeGroupName nodegroup name
	NodegroupName string
	// KubernetesVersion EKS version
	KubernetesVersion string
	// LaunchTemplateVersion launch template version
	// valid only if a nodegroup was created with a launch template
