Create Nodegroup

eks_create_nodegroup R Documentation

Creates a managed node group for an Amazon EKS cluster

Description

Creates a managed node group for an Amazon EKS cluster.

You can only create a node group for your cluster that is equal to the current Kubernetes version for the cluster. All node groups are created with the latest AMI release version for the respective minor Kubernetes version of the cluster, unless you deploy a custom AMI using a launch template. For more information about using launch templates, see Customizing managed nodes with launch templates.

An Amazon EKS managed node group is an Amazon EC2 Auto Scaling group and associated Amazon EC2 instances that are managed by Amazon Web Services for an Amazon EKS cluster. For more information, see Managed node groups in the Amazon EKS User Guide.

Windows AMI types are only supported for commercial Amazon Web Services Regions that support Windows on Amazon EKS.

Usage

eks_create_nodegroup(clusterName, nodegroupName, scalingConfig,
  diskSize, subnets, instanceTypes, amiType, remoteAccess, nodeRole,
  labels, taints, tags, clientRequestToken, launchTemplate, updateConfig,
  capacityType, version, releaseVersion)

Arguments

clusterName

[required] The name of your cluster.

nodegroupName

[required] The unique name to give your node group.

scalingConfig

The scaling configuration details for the Auto Scaling group that is created for your node group.

diskSize

The root device disk size (in GiB) for your node group instances. The default disk size is 20 GiB for Linux and Bottlerocket. The default disk size is 50 GiB for Windows. If you specify launchTemplate, then don't specify diskSize, or the node group deployment will fail. For more information about using launch templates with Amazon EKS, see Customizing managed nodes with launch templates in the Amazon EKS User Guide.

subnets

[required] The subnets to use for the Auto Scaling group that is created for your node group. If you specify launchTemplate, then don't specify SubnetId in your launch template, or the node group deployment will fail. For more information about using launch templates with Amazon EKS, see Customizing managed nodes with launch templates in the Amazon EKS User Guide.

instanceTypes

Specify the instance types for a node group. If you specify a GPU instance type, make sure to also specify an applicable GPU AMI type with the amiType parameter. If you specify launchTemplate, then you can specify zero or one instance type in your launch template or you can specify 0-20 instance types for instanceTypes. If however, you specify an instance type in your launch template and specify any instanceTypes, the node group deployment will fail. If you don't specify an instance type in a launch template or for instanceTypes, then t3.medium is used, by default. If you specify Spot for capacityType, then we recommend specifying multiple values for instanceTypes. For more information, see Managed node group capacity types and Customizing managed nodes with launch templates in the Amazon EKS User Guide.

amiType

The AMI type for your node group. If you specify launchTemplate, and your launch template uses a custom AMI, then don't specify amiType, or the node group deployment will fail. If your launch template uses a Windows custom AMI, then add eks:kube-proxy-windows to your Windows nodes rolearn in the aws-auth ConfigMap. For more information about using launch templates with Amazon EKS, see Customizing managed nodes with launch templates in the Amazon EKS User Guide.

remoteAccess

The remote access configuration to use with your node group. For Linux, the protocol is SSH. For Windows, the protocol is RDP. If you specify launchTemplate, then don't specify remoteAccess, or the node group deployment will fail. For more information about using launch templates with Amazon EKS, see Customizing managed nodes with launch templates in the Amazon EKS User Guide.

nodeRole

[required] The Amazon Resource Name (ARN) of the IAM role to associate with your node group. The Amazon EKS worker node kubelet daemon makes calls to Amazon Web Services APIs on your behalf. Nodes receive permissions for these API calls through an IAM instance profile and associated policies. Before you can launch nodes and register them into a cluster, you must create an IAM role for those nodes to use when they are launched. For more information, see Amazon EKS node IAM role in the Amazon EKS User Guide . If you specify launchTemplate, then don't specify IamInstanceProfile in your launch template, or the node group deployment will fail. For more information about using launch templates with Amazon EKS, see Customizing managed nodes with launch templates in the Amazon EKS User Guide.

labels

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

taints

The Kubernetes taints to be applied to the nodes in the node group. For more information, see Node taints on managed node groups.

tags

Metadata that assists with categorization and organization. Each tag consists of a key and an optional value. You define both. Tags don't propagate to any other cluster or Amazon Web Services resources.

clientRequestToken

A unique, case-sensitive identifier that you provide to ensure the idempotency of the request.

launchTemplate

An object representing a node group's launch template specification. When using this object, don't directly specify instanceTypes, diskSize, or remoteAccess. Make sure that the launch template meets the requirements in launchTemplateSpecification. Also refer to Customizing managed nodes with launch templates in the Amazon EKS User Guide.

updateConfig

The node group update configuration.

capacityType

The capacity type for your node group.

version

The Kubernetes version to use for your managed nodes. By default, the Kubernetes version of the cluster is used, and this is the only accepted specified value. If you specify launchTemplate, and your launch template uses a custom AMI, then don't specify version, or the node group deployment will fail. For more information about using launch templates with Amazon EKS, see Customizing managed nodes with launch templates in the Amazon EKS User Guide.

releaseVersion

The AMI version of the Amazon EKS optimized AMI to use with your node group. By default, the latest available AMI version for the node group's current Kubernetes version is used. For information about Linux versions, see Amazon EKS optimized Amazon Linux AMI versions in the Amazon EKS User Guide. Amazon EKS managed node groups support the November 2022 and later releases of the Windows AMIs. For information about Windows versions, see Amazon EKS optimized Windows AMI versions in the Amazon EKS User Guide.

If you specify launchTemplate, and your launch template uses a custom AMI, then don't specify releaseVersion, or the node group deployment will fail. For more information about using launch templates with Amazon EKS, see Customizing managed nodes with launch templates in the Amazon EKS User Guide.
