CfnNodegroup L1 construct ​

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 .

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

The AMI type for your node group.
notes

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 .

The root device disk size (in GiB) for your node group instances.
notes

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 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.

instanceTypesoptionalstring[]instance_typesoptionaltyping.List[str]instanceTypesoptionalList<String>InstanceTypesoptionalstring[]InstanceTypesoptional*[]*string#
Specify the instance types for a node group.
notes

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 .

The Amazon Resource Name (ARN) of the IAM role to associate with your node group.
notes

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 .

releaseVersionoptionalstringrelease_versionoptionalstrreleaseVersionoptionalStringReleaseVersionoptionalstringReleaseVersionoptional*string#
The AMI version of the Amazon EKS optimized AMI to use with your node group (for example, `1.14.7- *YYYYMMDD*` ). By default, the latest available AMI version for the node group's current Kubernetes version is used. For more information, see [Amazon EKS optimized Linux AMI Versions](https://docs.aws.amazon.com/eks/latest/userguide/eks-linux-ami-versions.html) in the *Amazon EKS User Guide* .

Changing this value triggers an update of the node group if one is available. You can't update other properties at the same time as updating Release Version .

Syntactic sugar for `addOverride(path, undefined)`.
1 parameter

Parameters

  • pathpathpathpathPath — The path of the value to delete.
addDependency(target: CfnResource): voiddef add_dependency(self, target: CfnResource) -> Nonepublic void addDependency(CfnResource target)public void AddDependency(CfnResource target)func AddDependency(Target CfnResource)deprecated#
Use `addResourceDependency` instead.

This method has been renamed to addResourceDependency to more clearly set it apart from construct.node.addDependency. See the documentation of that function for more details.

addDependsOn(target: CfnResource): voiddef add_depends_on(self, target: CfnResource) -> Nonepublic void addDependsOn(CfnResource target)public void AddDependsOn(CfnResource target)func AddDependsOn(Target CfnResource)deprecated#
Use `addResourceDependency` instead.
notes

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

This method has been renamed to addResourceDependency, which makes it more clear that this method operates at a different level from the construct-level construct.node.addDependency() mechanism.

addMetadata(key: string, value: any): voiddef add_metadata(self, key: str, value: Any) -> Nonepublic void addMetadata(String key, Object value)public void AddMetadata(string key, object value)func AddMetadata(Key *string, Value interface{})#

addOverride(path: string, value: any): voiddef add_override(self, path: str, value: Any) -> Nonepublic void addOverride(String path, Object value)public void AddOverride(string path, object value)func AddOverride(Path *string, Value interface{})#
Adds an override to the synthesized CloudFormation resource.
notes · 2 parameters

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,

typescript
cfnResource.addOverride('Properties.GlobalSecondaryIndexes.0.Projection.NonKeyAttributes', ['myattribute']);
cfnResource.addOverride('Properties.GlobalSecondaryIndexes.1.ProjectionType', 'INCLUDE');

would add the overrides

json
"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

  • pathpathpathpathPath — - The path of the property, you can use dot notation to override values in complex types.
  • valuevaluevaluevalueValue — - The value.

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

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

This method only adds dependencies between L1 resources. If you are looking for a generic construct-to-construct dependency mechanism that works for all constructs including L2s, use construct.node.addDependency instead.

Sets the cross-stack reference strength for this resource.

When set, any cross-stack reference to this resource will use the specified strength instead of the global default from the consuming stack's context.

1 parameter

Parameters

  • strengthstrengthstrengthstrengthStrength — - The reference strength to use for this resource.
applyRemovalPolicy(policy?: RemovalPolicy, options?: RemovalPolicyOptions): voiddef apply_removal_policy(self, policy: typing.Optional[RemovalPolicy] = None, options: typing.Optional[RemovalPolicyOptions] = None) -> Nonepublic void applyRemovalPolicy(RemovalPolicy policy, RemovalPolicyOptions options)public void ApplyRemovalPolicy(RemovalPolicy? policy = null, RemovalPolicyOptions? options = null)func ApplyRemovalPolicy(Policy RemovalPolicy, Options RemovalPolicyOptions)#
Sets the deletion policy of the resource based on the removal policy specified.
notes

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:

notes · 1 parameter · returns

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

  • xxxxX — Any object.

Returns: true if x is an object created from a class which extends Construct.
