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 Launch template support. 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. Each node group uses a version of the Amazon EKS optimized Amazon Linux 2 AMI. For more information, see Managed Node Groups in the Amazon EKS User Guide.

Parameters

-AmiType <AMITypes>
The AMI type for your node group. GPU instance types should use the AL2_x86_64_GPU AMI type. Non-GPU instances should use the AL2_x86_64 AMI type. Arm instances should use the AL2_ARM_64 AMI type. All types use the Amazon EKS optimized Amazon Linux 2 AMI. If you specify launchTemplate, and your launch template uses a custom AMI, then don't specify amiType, or the node group deployment will fail. For more information about using launch templates with Amazon EKS, see Launch template support in the Amazon EKS User Guide.

Unique, case-sensitive identifier that you provide to ensure the idempotency of the request.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-ClusterName <String>
The name of the cluster to create the node group in.
Required?True
Position?Named
Accept pipeline input?True (ByPropertyName)
-DiskSize <Int32>
The root device disk size (in GiB) for your node group instances. The default disk size is 20 GiB. 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 Launch template support in the Amazon EKS User Guide.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
This parameter overrides confirmation prompts to force the cmdlet to continue its operation. This parameter should always be used with caution.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-InstanceType <String[]>
Specify the instance types for a node group. If you specify a GPU instance type, be sure to specify AL2_x86_64_GPU 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 Launch template support in the Amazon EKS User Guide.

-LaunchTemplate_Name <String>
The name of the launch template.
Required?False

The unique name to give your node group.
Required?True
Position?1
Accept pipeline input?True (ByValue, ByPropertyName)
-NodeRole <String>
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 Launch template support in the Amazon EKS User Guide.
Required?True
Position?Named
Accept pipeline input?True (ByPropertyName)
-PassThru <SwitchParameter>

Position?Named
Accept pipeline input?True (ByPropertyName)
-ReleaseVersion <String>
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 more information, see Amazon EKS optimized Amazon Linux 2 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 Launch template support in the Amazon EKS User Guide.
Required?False

Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-RemoteAccess_SourceSecurityGroup <String[]>
The security groups that are allowed SSH access (port 22) to the nodes. 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 nodes is opened to the internet (0.0.0.0/0). For more information, see Security Groups for Your VPC in the Amazon Virtual Private Cloud User Guide.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
AliasesRemoteAccess_SourceSecurityGroups
-ScalingConfig_DesiredSize <Int32>
The current number of nodes that the managed node group should maintain.If you use Cluster Autoscaler, you shouldn't change the desiredSize value directly, as this can cause the Cluster Autoscaler to suddenly scale up or scale down.Whenever this parameter changes, the number of worker nodes in the node group is updated to the specified size. If this parameter is given a value that is smaller than the current number of running worker nodes, the necessary number of worker nodes are terminated to match the given value. When using CloudFormation, no action occurs if you remove this parameter from your CFN template.This parameter can be different from minSize in some cases, such as when starting with extra hosts for testing. This parameter can also be different when you want to start with an estimated number of needed hosts, but let Cluster Autoscaler reduce the number if there are too many. When Cluster Autoscaler is used, the desiredSize parameter is altered by Cluster Autoscaler (but can be out-of-date for short periods of time). Cluster Autoscaler doesn't scale a managed node group lower than minSize or higher than maxSize.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-ScalingConfig_MaxSize <Int32>
The maximum number of nodes that the managed node group can scale out to. For information about the maximum number that you can specify, see Amazon EKS service quotas in the Amazon EKS User Guide.

Accept pipeline input?True (ByPropertyName)
-Select <String>
Use the -Select parameter to control the cmdlet output. The default value is 'Nodegroup'. Specifying -Select '*' will result in the cmdlet returning the whole service response (Amazon.EKS.Model.CreateNodegroupResponse). Specifying the name of a property of type Amazon.EKS.Model.CreateNodegroupResponse will result in that property being returned. Specifying -Select '^ParameterName' will result in the cmdlet returning the selected cmdlet parameter value.
Required?False

-Subnet <String[]>
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.
