A CloudFormation AWS::EKS::Nodegroup.

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 AWS for an Amazon EKS cluster. For more information, see Managed node groups in the Amazon EKS User Guide . .. epigraph:

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

id (str) –
- scoped id of the resource.
cluster_name (str) – The name of the cluster to create the node group in.
node_role (str) –
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 AWS 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 <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 in the Amazon EKS User Guide .
subnets (Sequence[str]) –
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>`_ 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 .
ami_type (Optional[str]) –
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 Launch template support in the Amazon EKS User Guide .
capacity_type (Optional[str]) – The capacity type of your managed node group.
disk_size (Union[int, float, None]) –
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 Launch template support in the Amazon EKS User Guide .
force_update_enabled (Union[bool, IResolvable, None]) – 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.
instance_types (Optional[Sequence[str]]) –
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 Launch template support in the Amazon EKS User Guide .
labels (Union[IResolvable, Mapping[str, str], None]) – The Kubernetes labels applied to the nodes in the node group. .. epigraph:: Only labels that are applied with the Amazon EKS API are shown here. There may be other Kubernetes labels applied to the nodes in this group.
launch_template (Union[IResolvable, LaunchTemplateSpecificationProperty, Dict[str, Any], None]) – An object representing a node group’s launch template specification.

Methods

add_deletion_override(path)

Syntactic sugar for addOverride(path, undefined).

Parameters:: path (str) – The path of the value to delete.
Return type:: None

add_depends_on(target)

Indicates that this resource depends on another resource and cannot be provisioned unless the other resource has been successfully provisioned.

This can be used for resources across stacks (or nested stack) boundaries and the dependency will automatically be transferred to the relevant scope.

Parameters:

target (CfnResource) –

Return type:

None

add_metadata(key, value)

Add a value to the CloudFormation Resource Metadata.

Parameters:

key (str) –
value (Any) –

See:

Return type:

None

https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/metadata-section-structure.html

Note that this is a different set of metadata from CDK node metadata; this metadata ends up in the stack template under the resource, whereas CDK node metadata ends up in the Cloud Assembly.

add_override(path, value)

Adds an override to the synthesized CloudFormation resource.

To add a property override, either use addPropertyOverride or prefix path with “Properties.” (i.e. Properties.TopicName).

If the override is nested, separate each nested level using a dot (.) in the path parameter. If there is an array as part of the nesting, specify the index in the path.

To include a literal . in the property name, prefix with a \. In most programming languages you will need to write this as "\\." because the \ itself will need to be escaped.

For example:

cfn_resource.add_override("Properties.GlobalSecondaryIndexes.0.Projection.NonKeyAttributes", ["myattribute"])
cfn_resource.add_override("Properties.GlobalSecondaryIndexes.1.ProjectionType", "INCLUDE")

would add the overrides Example:

"Properties": {
   "GlobalSecondaryIndexes": [
     {
       "Projection": {
         "NonKeyAttributes": [ "myattribute" ]
         ...
       }
       ...
     },
     {
       "ProjectionType": "INCLUDE"
       ...
     },
   ]
   ...
}

The value argument to addOverride will not be processed or translated in any way. Pass raw JSON values in here with the correct capitalization for CloudFormation. If you pass CDK classes or structs, they will be rendered with lowercased key names, and CloudFormation will reject the template.

Parameters:

path (str) –
- The path of the property, you can use dot notation to override values in complex types. Any intermdediate keys will be created as needed.
value (Any) –
- The value. Could be primitive or complex.

Return type:

None

add_property_deletion_override(property_path)

Adds an override that deletes the value of a property from the resource definition.

Parameters:: property_path (str) – The path to the property.
Return type:: None

add_property_override(property_path, value)

Adds an override to a resource property.

Syntactic sugar for addOverride("Properties.<...>", value).

Parameters:

property_path (str) – The path of the property.
value (Any) – The value.

Return type:

None

apply_removal_policy(policy=None, *, apply_to_update_replace_policy=None, default=None)

Sets the deletion policy of the resource based on the removal policy specified.

The Removal Policy controls what happens to this resource when it stops being managed by CloudFormation, either because you’ve removed it from the CDK application or because you’ve made a change that requires the resource to be replaced.

The resource can be deleted (RemovalPolicy.DESTROY), or left in your AWS account for data recovery and cleanup later (RemovalPolicy.RETAIN).

Parameters:

policy (Optional[RemovalPolicy]) –
apply_to_update_replace_policy (Optional[bool]) – Apply the same deletion policy to the resource’s “UpdateReplacePolicy”. Default: true
default (Optional[RemovalPolicy]) – The default policy to apply in case the removal policy is not defined. Default: - Default value is resource specific. To determine the default value for a resoure, please consult that specific resource’s documentation.

Return type:

None

get_att(attribute_name)

Returns a token for an runtime attribute of this resource.

Ideally, use generated attribute accessors (e.g. resource.arn), but this can be used for future compatibility in case there is no generated attribute.

Parameters:: attribute_name (str) – The name of the attribute.
Return type:: Reference

get_metadata(key)

Retrieve a value value from the CloudFormation Resource Metadata.

Parameters:

key (str) –

See:

Return type:

Any

https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/metadata-section-structure.html

Note that this is a different set of metadata from CDK node metadata; this metadata ends up in the stack template under the resource, whereas CDK node metadata ends up in the Cloud Assembly.

Examines the CloudFormation resource and discloses attributes.

Parameters:

inspector (TreeInspector) –

tree inspector to collect and process attributes.

Return type:

None

ScalingConfigProperty

class CfnNodegroup.ScalingConfigProperty(*, desired_size=None, max_size=None, min_size=None)

Bases: object

An object representing the scaling configuration details for the Auto Scaling group that is associated with your node group.

When creating a node group, you must specify all or none of the properties. When updating a node group, you can specify any or none of the properties.

Parameters:

desired_size (Union[int, float, None]) – The current number of nodes that the managed node group should maintain. .. epigraph:: 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.
max_size (Union[int, float, None]) – 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 .
min_size (Union[int, float, None]) – The minimum number of nodes that the managed node group can scale in to.
