Bases: CfnResource

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 later updates, you will only be able to update a node group using a launch template only if it was originally deployed with a launch template. Additionally, the launch template ID or name must match what was used when the node group was created. You can update the launch template version with necessary changes. 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 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 AWS Regions that support Windows on Amazon EKS.

id (str) – Construct identifier for this resource (unique in its scope).
cluster_name (str) – The name of your cluster.
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 Customizing managed nodes with launch templates 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 Customizing managed nodes with launch templates 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 Customizing managed nodes with launch templates 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 Customizing managed nodes with launch templates in the Amazon EKS User Guide .
force_update_enabled (Union[bool, IResolvable, None]) – Force the update if any Pod on the existing node group can’t be drained due to a Pod disruption budget issue. If an update fails because all Pods can’t be drained, you can force the update after it fails to terminate the old node whether or not any Pod is running on the node. Default: - false
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 Customizing managed nodes with launch templates in the Amazon EKS User Guide .
labels (Union[Mapping[str, str], IResolvable, 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. When using this object, don’t directly specify instanceTypes , diskSize , or remoteAccess . You cannot later specify a different launch template ID or name than what was used to create the node group. Make sure that the launch template meets the requirements in launchTemplateSpecification .

You can’t update other properties at the same time as updating Release Version .
remote_access (Union[IResolvable, RemoteAccessProperty, Dict[str, Any], None]) –
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.

Effect is one of No_Schedule , Prefer_No_Schedule , or No_Execute . Kubernetes taints can be used together with tolerations to control how workloads are scheduled to your nodes. For more information, see Node taints on managed node groups .
update_config (Union[IResolvable, UpdateConfigProperty, Dict[str, Any], None]) – The node group update configuration.
version (Optional[str]) – 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.

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_dependency(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_depends_on(target)

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

Parameters:

target (CfnResource) –

Deprecated:

use addDependency

Stability:

deprecated

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 intermediate 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). In some cases, a snapshot can be taken of the resource prior to deletion (RemovalPolicy.SNAPSHOT). A list of resources that support this policy can be found in the following link:

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 resource, please consult that specific resource’s documentation.

See:

https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-attribute-deletionpolicy.html#aws-attribute-deletionpolicy-options

Return type:

None

get_att(attribute_name, type_hint=None)

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.
type_hint (Optional[ResolutionTypeHint]) –

Return type:

Reference

get_metadata(key)

Retrieve a value value from the CloudFormation Resource Metadata.

Static Methods

classmethod is_cfn_element(x)

Returns true if a construct is a stack element (i.e. part of the synthesized cloudformation template).

Uses duck-typing instead of instanceof to allow stack elements from different versions of this library to be included in the same stack.

Parameters:

x (Any) –

Return type:

bool

Returns:

The construct as a stack element or undefined if it is not a stack element.

classmethod is_cfn_resource(x)

Check whether the given object is a CfnResource.

Parameters:

x (Any) –

Return type:

bool

classmethod is_construct(x)

Checks if x is a construct.

Use this method instead of instanceof to properly detect Construct instances, even when the construct library is symlinked.

Explanation: in JavaScript, multiple copies of the constructs library on disk are seen as independent, completely different libraries. As a consequence, the class Construct in each copy of the constructs library is seen as a different class, and an instance of one class will not test as instanceof the other class. npm install will not create installations like this, but users may manually symlink construct libraries together or use a monorepo tool: in those cases, multiple copies of the constructs library can be accidentally installed, and instanceof will behave unpredictably. It is safest to avoid using instanceof, and using this type-testing method instead.

Parameters:: x (Any) – Any object.
Return type:: bool
Returns:: true if x is an object created from a class which extends Construct.

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

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.

TaintProperty

class CfnNodegroup.TaintProperty(*, effect=None, key=None, value=None)

Bases: object

A property that allows a node to repel a Pod .

For more information, see Node taints on managed node groups in the Amazon EKS User Guide .

Parameters:

effect (Optional[str]) – The effect of the taint.
key (Optional[str]) – The key of the taint.
value (Optional[str]) – The value of the taint.

UpdateConfigProperty

class CfnNodegroup.UpdateConfigProperty(*, max_unavailable=None, max_unavailable_percentage=None, update_strategy=None)

Bases: object

The update configuration for the node group.

Parameters:

max_unavailable (Union[int, float, None]) – The maximum number of nodes unavailable at once during a version update. Nodes are updated in parallel. This value or maxUnavailablePercentage is required to have a value.The maximum number is 100.
max_unavailable_percentage (Union[int, float, None]) – The maximum percentage of nodes unavailable during a version update. This percentage of nodes are updated in parallel, up to 100 nodes at once. This value or maxUnavailable is required to have a value.
update_strategy (Optional[str]) – The configuration for the behavior to follow during a node group version update of this managed node group. You choose between two possible strategies for replacing nodes during an `UpdateNodegroupVersion <https://docs.aws.amazon.com/eks/latest/APIReference/API_UpdateNodegroupVersion.html>`_ action. An Amazon EKS managed node group updates by replacing nodes with new nodes of newer AMI versions in parallel. The update strategy changes the managed node update behavior of the managed node group for each quantity. The default strategy has guardrails to protect you from misconfiguration and launches the new instances first, before terminating the old instances. The minimal strategy removes the guardrails and terminates the old instances before launching the new instances. This minimal strategy is useful in scenarios where you are constrained to resources or costs (for example, with hardware accelerators such as GPUs).
