aws_cdk.aws_eks.CommonClusterOptions
Options for EKS clusters.
- Parameters
version (
KubernetesVersion
) – The Kubernetes version to run in the cluster.cluster_name (
Optional
[str
]) – Name for the cluster. Default: - Automatically generated nameoutput_cluster_name (
Optional
[bool
]) – Determines whether a CloudFormation output with the name of the cluster will be synthesized. Default: falseoutput_config_command (
Optional
[bool
]) – Determines whether a CloudFormation output with theaws eks update-kubeconfig
command will be synthesized. This command will include the cluster name and, if applicable, the ARN of the masters IAM role. Default: truerole (
Optional
[IRole
]) – Role that provides permissions for the Kubernetes control plane to make calls to AWS API operations on your behalf. Default: - A role is automatically created for yousecurity_group (
Optional
[ISecurityGroup
]) – Security Group to use for Control Plane ENIs. Default: - A security group is automatically createdvpc (
Optional
[IVpc
]) – The VPC in which to create the Cluster. Default: - a VPC with default configuration will be created and can be accessed throughcluster.vpc
.vpc_subnets (
Optional
[Sequence
[SubnetSelection
]]) – Where to place EKS Control Plane ENIs. If you want to create public load balancers, this must include public subnets.

Optional
[ILayerVersion
]) – An AWS Lambda Layer which includeskubectl
, 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 theaws-lambda-layer-kubectl

Kubernetes RBAC group. Default: - a role that assumable by anyone with permissions in the same account will automatically be definedoutput_masters_role_arn (
Optional
[bool
]) – Determines whether a CloudFormation output with the ARN of the “masters” IAM role will be synthesized (ifmastersRole
is specified). Default: falseplace_cluster_handler_in_vpc (
Optional
[bool
]) – If set to true, the cluster handler functions will be placed in the private subnets of the cluster vpc, subject to thevpcSubnets
selection strategy. Default: falseprune (
Optional
[bool
]) – Indicates whether Kubernetes resources added throughaddManifest()
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 thekubectl apply
operation with the--prune
switch. Default: truesecrets_encryption_key (
Optional
[IKey
]) – 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.
