  • Method Details

    • getKubectlLayer

      @Stability(Stable) @NotNull ILayerVersion getKubectlLayer()
      An AWS Lambda Layer which includes kubectl and Helm.

      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

    • getAlbController

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

      Default: - The controller is not installed.

      See Also:

    • getAuthenticationMode

      @Stability(Stable) @Nullable default AuthenticationMode getAuthenticationMode()
      The desired authentication mode for the cluster.

      Default: AuthenticationMode.CONFIG_MAP

    • getAwscliLayer

      @Stability(Stable) @Nullable default ILayerVersion getAwscliLayer()
      An AWS Lambda layer that contains the aws CLI.

      The handler expects the layer to include the following executables: 

       /opt/awscli/aws

      Default: - a default layer with the AWS CLI 1.x

    • 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.

    • getClusterLogging

      @Stability(Stable) @Nullable default List<ClusterLoggingTypes> getClusterLogging()
      The cluster log types which you want to enable.

      Default: - none

    • 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:

    • getIpFamily

      @Stability(Stable) @Nullable default IpFamily getIpFamily()
      Specify which IP family is used to assign Kubernetes pod and service IP addresses.

      Default: - IpFamily.IP_V4

      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.

    • 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: - no masters role.

      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_LATEST))
         .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

    • getRemoteNodeNetworks

      @Stability(Stable) @Nullable default List<RemoteNodeNetwork> getRemoteNodeNetworks()
      IPv4 CIDR blocks defining the expected address range of hybrid nodes that will join the cluster.

      Default: - none

    • getRemotePodNetworks

      @Stability(Stable) @Nullable default List<RemotePodNetwork> getRemotePodNetworks()
      IPv4 CIDR blocks for Pods running Kubernetes webhooks on hybrid nodes.

      Default: - none

    • getRemovalPolicy

      @Stability(Stable) @Nullable default RemovalPolicy getRemovalPolicy()
      The removal policy applied to all CloudFormation resources created by this construct when they are no longer managed by CloudFormation.

      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.

      Default: - Resources will be deleted.

    • getSecretsEncryptionKey

      @Stability(Stable) @Nullable default IKeyRef 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

      Returns:
      a ClusterOptions.Builder of ClusterOptions
