// templates, see Launch template support
// (https://docs.aws.amazon.com/eks/latest/userguide/launch-templates.html). 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

// This member is required.
ClusterName *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
// (https://docs.aws.amazon.com/eks/latest/userguide/create-node-role.html) in the
// Amazon EKS User Guide . If you specify launchTemplate, then don't specify
// IamInstanceProfile
// (https://docs.aws.amazon.com/AWSEC2/latest/APIReference/API_IamInstanceProfile.html)
// 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 (https://docs.aws.amazon.com/eks/latest/userguide/launch-templates.html)
// in the Amazon EKS User Guide.
//
// This member is required.
NodeRole *string
// The unique name to give your node group.
//
// This member is required.
NodegroupName *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
// (https://docs.aws.amazon.com/AWSEC2/latest/APIReference/API_CreateNetworkInterface.html)

// support (https://docs.aws.amazon.com/eks/latest/userguide/launch-templates.html)
// in the Amazon EKS User Guide.
//
// This member is required.
Subnets []string
// 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
// (https://docs.aws.amazon.com/eks/latest/userguide/launch-templates.html) in the
// Amazon EKS User Guide.
AmiType types.AMITypes
// The capacity type for your node group.
CapacityType types.CapacityTypes
// Unique, case-sensitive identifier that you provide to ensure the idempotency of
// the request.
ClientRequestToken *string
// 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
// (https://docs.aws.amazon.com/eks/latest/userguide/launch-templates.html) in the
// Amazon EKS User Guide.
DiskSize *int32
// 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
// (https://docs.aws.amazon.com/eks/latest/userguide/managed-node-groups.html#managed-node-group-capacity-types)
// and Launch template support
// (https://docs.aws.amazon.com/eks/latest/userguide/launch-templates.html) in the
// Amazon EKS User Guide.
InstanceTypes []string
// The Kubernetes labels to be applied to the nodes in the node group when they are
// created.
Labels map[string]string
// An object representing a node group's launch template specification. If
// specified, then do not specify instanceTypes, diskSize, or remoteAccess and make
// sure that the launch template meets the requirements in
// launchTemplateSpecification.
LaunchTemplate *types.LaunchTemplateSpecification
// 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
// (https://docs.aws.amazon.com/eks/latest/userguide/eks-linux-ami-versions.html)
// in the Amazon EKS User Guide. If you specify launchTemplate, and your launch

// deployment will fail. For more information about using launch templates with
// Amazon EKS, see Launch template support
// (https://docs.aws.amazon.com/eks/latest/userguide/launch-templates.html) in the
// Amazon EKS User Guide.
ReleaseVersion *string
// The remote access (SSH) configuration to use with your node group. 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 Launch template support
// (https://docs.aws.amazon.com/eks/latest/userguide/launch-templates.html) in the
// Amazon EKS User Guide.
RemoteAccess *types.RemoteAccessConfig
// The scaling configuration details for the Auto Scaling group that is created for
// your node group.
ScalingConfig *types.NodegroupScalingConfig
// The metadata to apply to the node group to assist with categorization and
// organization. Each tag consists of a key and an optional value. You define both.
// Node group tags do not propagate to any other resources associated with the node
// group, such as the Amazon EC2 instances or subnets.
Tags map[string]string
// The Kubernetes taints to be applied to the nodes in the node group. For more
// information, see Node taints on managed node groups
// (https://docs.aws.amazon.com/eks/latest/userguide/node-taints-managed-node-groups.html).
Taints []types.Taint
// The node group update configuration.
UpdateConfig *types.NodegroupUpdateConfig
// 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
