  • Method Details

    • getAlbController

      @Stability(Stable) @Nullable default AlbControllerOptions getAlbController()
      Install the AWS Load Balancer Controller onto the cluster.

      Default: - The controller is not installed.

      See Also:

    • getClusterHandlerEnvironment

      @Stability(Stable) @Nullable default Map<String,String> getClusterHandlerEnvironment()
      Custom environment variables when interacting with the EKS endpoint to manage the cluster lifecycle.

      Default: - No environment variables.

    • getClusterHandlerSecurityGroup

      @Stability(Stable) @Nullable default ISecurityGroup getClusterHandlerSecurityGroup()
      A security group to associate with the Cluster Handler's Lambdas.

      The Cluster Handler's Lambdas are responsible for calling AWS's EKS API.

      Requires placeClusterHandlerInVpc to be set to true.

      Default: - No security group.

    • getCoreDnsComputeType

      @Stability(Stable) @Nullable default CoreDnsComputeType getCoreDnsComputeType()
      Controls the "eks.amazonaws.com/compute-type" annotation in the CoreDNS configuration on your cluster to determine which compute type to use for CoreDNS.

      Default: CoreDnsComputeType.EC2 (for `FargateCluster` the default is FARGATE)

    • getEndpointAccess

      @Stability(Stable) @Nullable default EndpointAccess getEndpointAccess()
      Configure access to the Kubernetes API server endpoint..

      Default: EndpointAccess.PUBLIC_AND_PRIVATE

      See Also:

    • getKubectlEnvironment

      @Stability(Stable) @Nullable default Map<String,String> getKubectlEnvironment()
      Environment variables for the kubectl execution.

      Only relevant for kubectl enabled clusters.

      Default: - No environment variables.

    • getKubectlLayer

      @Stability(Stable) @Nullable default ILayerVersion getKubectlLayer()
      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: 

       LayerVersion layer = LayerVersion.Builder.create(this, "kubectl-layer")
         .code(Code.fromAsset(String.format("%s/layer.zip", __dirname)))
         .compatibleRuntimes(List.of(Runtime.PROVIDED))
         .build();

      Default: - the layer provided by the `aws-lambda-layer-kubectl` SAR app.

      See Also:

    • getKubectlMemory

      @Stability(Stable) @Nullable default Size getKubectlMemory()
      Amount of memory to allocate to the provider's lambda function.

      Default: Size.gibibytes(1)

    • getMastersRole

      @Stability(Stable) @Nullable default IRole getMastersRole()
      An IAM role that will be added to the system:masters Kubernetes RBAC group.

      Default: - a role that assumable by anyone with permissions in the same account will automatically be defined

      See Also:

    • getOnEventLayer

      @Stability(Stable) @Nullable default ILayerVersion getOnEventLayer()
      An AWS Lambda Layer which includes the NPM dependency proxy-agent.

      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: 

       LayerVersion layer = LayerVersion.Builder.create(this, "proxy-agent-layer")
         .code(Code.fromAsset(String.format("%s/layer.zip", __dirname)))
         .compatibleRuntimes(List.of(Runtime.NODEJS_14_X))
         .build();

      Default: - a layer bundled with this module.

    • getOutputMastersRoleArn

      @Stability(Stable) @Nullable default Boolean getOutputMastersRoleArn()
      Determines whether a CloudFormation output with the ARN of the "masters" IAM role will be synthesized (if mastersRole is specified).

      Default: false

    • getPlaceClusterHandlerInVpc

      @Stability(Stable) @Nullable default Boolean getPlaceClusterHandlerInVpc()
      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

    • getPrune

      @Stability(Stable) @Nullable default Boolean getPrune()
      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

    • getSecretsEncryptionKey

      @Stability(Stable) @Nullable default IKey getSecretsEncryptionKey()
      KMS secret for envelope encryption for Kubernetes secrets.

      Default: - By default, Kubernetes stores all secret object data within etcd and all etcd volumes used by Amazon EKS are encrypted at the disk-level using AWS-Managed encryption keys.

    • getServiceIpv4Cidr

      @Stability(Stable) @Nullable default String getServiceIpv4Cidr()
      The CIDR block to assign Kubernetes service IP addresses from.

      Default: - Kubernetes assigns addresses from either the 10.100.0.0/16 or 172.20.0.0/16 CIDR blocks
