bootstrapClusterCreatorAdminPermissionsbooleanbootstrap_cluster_creator_admin_permissionsboolbootstrapClusterCreatorAdminPermissionsBooleanBootstrapClusterCreatorAdminPermissionsboolBootstrapClusterCreatorAdminPermissions*bool= true#
Whether or not IAM principal of the cluster creator was set as a cluster admin access entry during cluster creation time.

Changing this value after the cluster has been created will result in the cluster being replaced.

If you set this value to False when creating a cluster, the default networking add-ons will not be installed.
notes

The default networking addons include vpc-cni, coredns, and kube-proxy. Use this option when you plan to install third-party alternative add-ons or self-manage the default networking add-ons.

Changing this value after the cluster has been created will result in the cluster being replaced.

kubectlLayerILayerVersionkubectl_layerILayerVersionkubectlLayerILayerVersionKubectlLayerILayerVersionKubectlLayerILayerVersionrequired#
An AWS Lambda Layer which includes `kubectl` and Helm.
notes

This layer is used by the kubectl handler to apply manifests and install helm charts. You must pick an appropriate releases of one of the @aws-cdk/layer-kubectl-vXX packages, that works with the version of Kubernetes you have chosen.

The handler expects the layer to include the following executables:

/opt/helm/helm
/opt/kubectl/kubectl
kubectlMemorySizekubectl_memorySizekubectlMemorySizeKubectlMemorySizeKubectlMemorySize= Size.gibibytes(1)#
Amount of memory to allocate to the provider's lambda function.
mastersRoleIRolemasters_roleIRolemastersRoleIRoleMastersRoleIRoleMastersRoleIRole= no masters role.#
An IAM role that will be added to the `system:masters` Kubernetes RBAC group.
onEventLayerILayerVersionon_event_layerILayerVersiononEventLayerILayerVersionOnEventLayerILayerVersionOnEventLayerILayerVersion= a layer bundled with this module…#
An AWS Lambda Layer which includes the NPM dependency `proxy-agent`.
notes · default

This layer is used by the onEvent handler to route AWS SDK requests through a proxy.

By default, the provider will use the layer included in the "aws-lambda-layer-node-proxy-agent" SAR application which is available in all commercial regions.

To deploy the layer locally define it in your app as follows:

ts
const layer = new lambda.LayerVersion(this, 'proxy-agent-layer', {
  code: lambda.Code.fromAsset(`${__dirname}/layer.zip`),
  compatibleRuntimes: [lambda.Runtime.NODEJS_LATEST],
});

Default: a layer bundled with this module.

Determines whether a CloudFormation output with the name of the cluster will be synthesized.
outputConfigCommandbooleanoutput_config_commandbooloutputConfigCommandBooleanOutputConfigCommandboolOutputConfigCommand*bool= true#
Determines whether a CloudFormation output with the `aws eks update-kubeconfig` command will be synthesized.

This command will include the cluster name and the ARN of the masters IAM role.

Note: If mastersRole is not specified, this property will be ignored and no config command will be emitted.

outputMastersRoleArnbooleanoutput_masters_role_arnbooloutputMastersRoleArnBooleanOutputMastersRoleArnboolOutputMastersRoleArn*bool= false#
Determines whether a CloudFormation output with the ARN of the "masters" IAM role will be synthesized (if `mastersRole` is specified).

If set to true, the cluster handler functions will be placed in the private subnets of the cluster vpc, subject to the `vpcSubnets` selection strategy.
prunebooleanpruneboolpruneBooleanPruneboolPrune*bool= true#
Indicates whether Kubernetes resources added through `addManifest()` can be automatically pruned.

When this is enabled (default), prune labels will be allocated and injected to each resource. These labels will then be used when issuing the kubectl apply operation with the --prune switch.

IPv4 CIDR blocks defining the expected address range of hybrid nodes that will join the cluster.

IPv4 CIDR blocks for Pods running Kubernetes webhooks on hybrid nodes.
removalPolicyRemovalPolicyremoval_policyRemovalPolicyremovalPolicyRemovalPolicyRemovalPolicyRemovalPolicyRemovalPolicyRemovalPolicy= Resources will be deleted.#
The removal policy applied to all CloudFormation resources created by this construct when they are no longer managed by CloudFormation.
notes

This can happen in one of three situations:

  • The resource is removed from the template, so CloudFormation stops managing it;
  • A change to the resource is made that requires it to be replaced, so CloudFormation stops managing it;
  • The stack is deleted, so CloudFormation stops managing all resources in it.

This affects the EKS cluster itself, associated IAM roles, node groups, security groups, VPC and any other CloudFormation resources managed by this construct.
