create-nodegroup

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 .

Note

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

Options

--cluster-name (string)

The name of your cluster.

--nodegroup-name (string)

The unique name to give your node group.

--scaling-config (structure)

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

minSize -> (integer)

The minimum number of nodes that the managed node group can scale in to.

maxSize -> (integer)

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 .

desiredSize -> (integer)

The current number of nodes that the managed node group should maintain.

Warning

If you use the Kubernetes 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 the Cluster Autoscaler reduce the number if there are too many. When the Cluster Autoscaler is used, the desiredSize parameter is altered by the Cluster Autoscaler (but can be out-of-date for short periods of time). the Cluster Autoscaler doesn't scale a managed node group lower than minSize or higher than maxSize .

Shorthand Syntax:

minSize=integer,maxSize=integer,desiredSize=integer

JSON Syntax:

{
  "minSize": integer,
  "maxSize": integer,
  "desiredSize": integer
}

--disk-size (integer)

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 (list)

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 .

(string)

Syntax:

"string" "string" ...

--instance-types (list)

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 .

(string)

Syntax:

"string" "string" ...

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 .

desiredSize -> (integer)

The current number of nodes that the managed node group should maintain.

Warning

If you use the Kubernetes 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 the Cluster Autoscaler reduce the number if there are too many. When the Cluster Autoscaler is used, the desiredSize parameter is altered by the Cluster Autoscaler (but can be out-of-date for short periods of time). the Cluster Autoscaler doesn't scale a managed node group lower than minSize or higher than maxSize .

An object representing an issue with an Amazon EKS resource.

code -> (string)

A brief description of the error.

  • AccessDenied : Amazon EKS or one or more of your managed nodes is failing to authenticate or authorize with your Kubernetes cluster API server.
  • AsgInstanceLaunchFailures : Your Auto Scaling group is experiencing failures while attempting to launch instances.
  • AutoScalingGroupNotFound : We couldn't find the Auto Scaling group associated with the managed node group. You may be able to recreate an Auto Scaling group with the same settings to recover.
  • ClusterUnreachable : Amazon EKS or one or more of your managed nodes is unable to to communicate with your Kubernetes cluster API server. This can happen if there are network disruptions or if API servers are timing out processing requests.
  • Ec2InstanceTypeDoesNotExist : One or more of the supplied Amazon EC2 instance types do not exist. Amazon EKS checked for the instance types that you provided in this Amazon Web Services Region, and one or more aren't available.
  • Ec2LaunchTemplateNotFound : We couldn't find the Amazon EC2 launch template for your managed node group. You may be able to recreate a launch template with the same settings to recover.
  • Ec2LaunchTemplateVersionMismatch : The Amazon EC2 launch template version for your managed node group does not match the version that Amazon EKS created. You may be able to revert to the version that Amazon EKS created to recover.
  • Ec2SecurityGroupDeletionFailure : We could not delete the remote access security group for your managed node group. Remove any dependencies from the security group.
  • Ec2SecurityGroupNotFound : We couldn't find the cluster security group for the cluster. You must recreate your cluster.
  • Ec2SubnetInvalidConfiguration : One or more Amazon EC2 subnets specified for a node group do not automatically assign public IP addresses to instances launched into it. If you want your instances to be assigned a public IP address, then you need to enable the auto-assign public IP address setting for the subnet. See Modifying the public ``IPv4` addressing attribute for your subnet <https://docs.aws.amazon.com/vpc/latest/userguide/vpc-ip-addressing.html#subnet-public-ip>`__ in the Amazon VPC User Guide .
  • IamInstanceProfileNotFound : We couldn't find the IAM instance profile for your managed node group. You may be able to recreate an instance profile with the same settings to recover.
  • IamNodeRoleNotFound : We couldn't find the IAM role for your managed node group. You may be able to recreate an IAM role with the same settings to recover.
  • InstanceLimitExceeded : Your Amazon Web Services account is unable to launch any more instances of the specified instance type. You may be able to request an Amazon EC2 instance limit increase to recover.
  • InsufficientFreeAddresses : One or more of the subnets associated with your managed node group does not have enough available IP addresses for new nodes.
  • InternalFailure : These errors are usually caused by an Amazon EKS server-side issue.
  • NodeCreationFailure : Your launched instances are unable to register with your Amazon EKS cluster. Common causes of this failure are insufficient node IAM role permissions or lack of outbound internet access for the nodes.
