Common configuration props 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 name
output_cluster_name (Optional[bool]) – Determines whether a CloudFormation output with the name of the cluster will be synthesized. Default: false
output_config_command (Optional[bool]) – Determines whether a CloudFormation output with the aws 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: true
role (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 you
security_group (Optional[ISecurityGroup]) – Security Group to use for Control Plane ENIs. Default: - A security group is automatically created
vpc (Optional[IVpc]) – The VPC in which to create the Cluster. Default: - a VPC with default configuration will be created and can be accessed through cluster.vpc.
vpc_subnets (Optional[List[SubnetSelection]]) – Where to place EKS Control Plane ENIs. If you want to create public load balancers, this must include public subnets. For example, to only select private subnets, supply the following:: vpcSubnets: [ { subnetType: ec2.SubnetType.Private } ] Default: - All public and private subnets
core_dns_compute_type (Optional[CoreDnsComputeType]) – 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)
endpoint_access (Optional[EndpointAccess]) – Configure access to the Kubernetes API server endpoint.. Default: EndpointAccess.PUBLIC_AND_PRIVATE
kubectl_environment (Optional[Mapping[str, str]]) – Environment variables for the kubectl execution. Only relevant for kubectl enabled clusters. Default: - No environment variables.
masters_role (Optional[IRole]) – 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
output_masters_role_arn (Optional[bool]) – Determines whether a CloudFormation output with the ARN of the “masters” IAM role will be synthesized (if mastersRole is specified). Default: false
default_capacity (Union[int, float, None]) – Number of instances to allocate as an initial capacity for this cluster. Instance type can be configured through defaultCapacityInstanceType, which defaults to m5.large. Use cluster.addCapacity to add additional customized capacity. Set this to 0 is you wish to avoid the initial capacity allocation. Default: 2
default_capacity_instance (Optional[InstanceType]) – The instance type to use for the default capacity. This will only be taken into account if defaultCapacity is > 0. Default: m5.large
default_capacity_type (Optional[DefaultCapacityType]) – The default capacity type for the cluster. Default: NODEGROUP
kubectl_enabled (Optional[bool]) – NOT SUPPORTED: We no longer allow disabling kubectl-support. Setting this option to false will throw an error. To temporary allow you to retain existing clusters created with kubectlEnabled: false, you can use eks.LegacyCluster class, which is a drop-in replacement for eks.Cluster with kubectlEnabled: false. Bear in mind that this is a temporary workaround. We have plans to remove eks.LegacyCluster. If you have a use case for using eks.LegacyCluster, please add a comment here https://github.com/aws/aws-cdk/issues/9332 and let us know so we can make sure to continue to support your use case with eks.Cluster. This issue also includes additional context into why this class is being removed. Default: true

Attributes

cluster_name¶

Name for the cluster.

default :default: - Automatically generated name

stability :stability: experimental

Return type: Optional[str]

core_dns_compute_type¶

Controls the “eks.amazonaws.com/compute-type” annotation in the CoreDNS configuration on your cluster to determine which compute type to use for CoreDNS.

stability :stability: experimental

Return type: Optional[CoreDnsComputeType]

default_capacity¶

Number of instances to allocate as an initial capacity for this cluster.

Instance type can be configured through defaultCapacityInstanceType, which defaults to m5.large.

Use cluster.addCapacity to add additional customized capacity. Set this to 0 is you wish to avoid the initial capacity allocation.

default :default: 2

stability :stability: experimental

Return type: Union[int, float, None]

default_capacity_instance¶

kubectl_enabled¶

We no longer allow disabling kubectl-support. Setting this option to false will throw an error.

To temporary allow you to retain existing clusters created with kubectlEnabled: false, you can use eks.LegacyCluster class, which is a drop-in replacement for eks.Cluster with kubectlEnabled: false.

Bear in mind that this is a temporary workaround. We have plans to remove eks.LegacyCluster. If you have a use case for using eks.LegacyCluster, please add a comment here https://github.com/aws/aws-cdk/issues/9332 and let us know so we can make sure to continue to support your use case with eks.Cluster.
