kubectl_layer (Optional[ILayerVersion]) – (experimental) An AWS Lambda Layer which includes kubectl, Helm and the AWS CLI. By default, the provider will use the layer included in the “aws-lambda-layer-kubectl” SAR application which is available in all commercial regions. To deploy the layer locally, visit https://github.com/aws-samples/aws-lambda-layer-kubectl/blob/master/cdk/README.md for instructions on how to prepare the .zip file and then define it in your app as follows:: const layer = new lambda.LayerVersion(this, ‘kubectl-layer’, { code: lambda.Code.fromAsset(${__dirname}/layer.zip)), compatibleRuntimes: [lambda.Runtime.PROVIDED] }) Default: - the layer provided by the aws-lambda-layer-kubectl SAR app.

output_masters_role_arn (Optional[bool]) – (experimental) Determines whether a CloudFormation output with the ARN of the “masters” IAM role will be synthesized (if mastersRole is specified). Default: false
place_cluster_handler_in_vpc (Optional[bool]) – (experimental) 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. Default: false
prune (Optional[bool]) – (experimental) 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. Default: true
