Properties

OptionalamiReleaseVersion

amiReleaseVersion?: string

This property is used to upgrade node groups to the latest kubelet by upgrading node group AMI. Look up the versions here (mapped to Kubernetes version): https://docs.aws.amazon.com/eks/latest/userguide/eks-linux-ami-versions.html

OptionalamiType

amiType?: NodegroupAmiType

Choose AMI type for the managed node group.

OptionaldesiredSize

desiredSize?: number

Desired size, defaults to min size.

Optional ReadonlydiskSize

diskSize?: number

The root device disk size (in GiB) for your node group instances.

Default

20

OptionalenableSsmPermissions

enableSsmPermissions?: boolean

If set to true will add AmazonSSMManagedInstanceCore to the node role.

Optional ReadonlyforceUpdate

forceUpdate?: boolean

Force the update if the existing node group's pods are unable to be drained due to a pod disruption budget issue. If an update fails because pods could not be drained, you can force the update after it fails to terminate the old node whether or not any pods are running on the node.

Default

true

id

id: string

Id of this node group. Expected to be unique in cluster scope.

OptionalinstanceTypes

instanceTypes?: InstanceType[]

Instance types used for the node group. Multiple types makes sense if capacity type is SPOT.

Default

m5.large

Optional Readonlylabels

labels?: {
    [name: string]: string;
}

The Kubernetes labels to be applied to the nodes in the node group when they are created.

Default

- None

OptionallaunchTemplate

launchTemplate?: LaunchTemplateProps

The Launch Template properties for the Nodes. amiType and amiReleaseVersion will be ignored if this is set.

Optional ReadonlylaunchTemplateSpec

launchTemplateSpec?: LaunchTemplateSpec

Launch template specification used for the nodegroup

See

https://docs.aws.amazon.com/eks/latest/userguide/launch-templates.html

Default

- no launch template

OptionalmaxSize

maxSize?: number

Max size of the node group.

Default

3

Optional ReadonlymaxUnavailable

maxUnavailable?: number

The maximum number of nodes unavailable at once during a version update. Nodes will be updated in parallel. The maximum number is 100.

This value or maxUnavailablePercentage is required to have a value for custom update configurations to be applied.

See

https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-properties-eks-nodegroup-updateconfig.html#cfn-eks-nodegroup-updateconfig-maxunavailable

Default

1

Optional ReadonlymaxUnavailablePercentage

maxUnavailablePercentage?: number

The maximum percentage of nodes unavailable during a version update. This percentage of nodes will be updated in parallel, up to 100 nodes at once.

This value or maxUnavailable is required to have a value for custom update configurations to be applied.

See

https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-properties-eks-nodegroup-updateconfig.html#cfn-eks-nodegroup-updateconfig-maxunavailablepercentage

Default

undefined - node groups will update instances one at a time

OptionalminSize

minSize?: number

Min size of the node group

Default

1

OptionalnodeGroupCapacityType

nodeGroupCapacityType?: CapacityType

Select either SPOT or ON-DEMAND

Optional ReadonlynodegroupName

nodegroupName?: string

Name of the Nodegroup

Default

- resource ID

OptionalnodeGroupSubnets

nodeGroupSubnets?: SubnetSelection

Subnets for the autoscaling group where nodes (instances) will be placed.

Default

all private subnets

Optional ReadonlynodeRole

nodeRole?: IRole

The IAM role to associate with your node group. The Amazon EKS worker node kubelet daemon makes calls to AWS APIs on your behalf. Worker nodes receive permissions for these API calls through an IAM instance profile and associated policies. Before you can launch worker nodes and register them into a cluster, you must create an IAM role for those worker nodes to use when they are launched.

Default

- None. Auto-generated if not specified.

Optional ReadonlyremoteAccess

remoteAccess?: NodegroupRemoteAccess

The remote access (SSH) configuration to use with your node group. Disabled by default, however, if you specify an Amazon EC2 SSH key but do not specify a source security group when you create a managed node group, then port 22 on the worker nodes is opened to the internet (0.0.0.0/0)

Default

- disabled

Optional Readonlytags

tags?: {
    [name: string]: string;
}

The metadata to apply to the node group to assist with categorization and organization. Each tag consists of a key and an optional value, both of which you define. Node group tags do not propagate to any other resources associated with the node group, such as the Amazon EC2 instances or subnets.

Default

- None

Optional Readonlytaints

taints?: TaintSpec[]

The Kubernetes taints to be applied to the nodes in the node group when they are created.

Default

- None
