Attributes for EKS clusters.

Parameters

cluster_name (str) – The physical name of the Cluster.
cluster_certificate_authority_data (Optional[str]) – The certificate-authority-data for your cluster. Default: - if not specified cluster.clusterCertificateAuthorityData will throw an error
cluster_encryption_config_key_arn (Optional[str]) – Amazon Resource Name (ARN) or alias of the customer master key (CMK). Default: - if not specified cluster.clusterEncryptionConfigKeyArn will throw an error
cluster_endpoint (Optional[str]) – The API Server endpoint URL. Default: - if not specified cluster.clusterEndpoint will throw an error.
cluster_handler_security_group_id (Optional[str]) – A security group id to associate with the Cluster Handler’s Lambdas. The Cluster Handler’s Lambdas are responsible for calling AWS’s EKS API. Default: - No security group.
cluster_security_group_id (Optional[str]) – The cluster security group that was created by Amazon EKS for the cluster. Default: - if not specified cluster.clusterSecurityGroupId will throw an error
kubectl_environment (Optional[Mapping[str, str]]) – Environment variables to use when running kubectl against this cluster. Default: - no additional variables
kubectl_lambda_role (Optional[IRole]) – An IAM role that can perform kubectl operations against this cluster. The role should be mapped to the system:masters Kubernetes RBAC role. This role is directly passed to the lambda handler that sends Kube Ctl commands to the cluster. Default: - if not specified, the default role created by a lambda function will be used.
kubectl_layer (Optional[ILayerVersion]) – An AWS Lambda Layer which includes kubectl, Helm and the AWS CLI. This layer is used by the kubectl handler to apply manifests and install helm charts. The handler expects the layer to include the following executables:: helm/helm kubectl/kubectl awscli/aws Default: - a layer bundled with this module.
kubectl_memory (Optional[Size]) – Amount of memory to allocate to the provider’s lambda function. Default: Size.gibibytes(1)
kubectl_private_subnet_ids (Optional[Sequence[str]]) – Subnets to host the kubectl compute resources. If not specified, the k8s endpoint is expected to be accessible publicly. Default: - k8s endpoint is expected to be accessible publicly
kubectl_provider (Optional[IKubectlProvider]) – KubectlProvider for issuing kubectl commands. Default: - Default CDK provider
kubectl_role_arn (Optional[str]) – An IAM role with cluster administrator and “system:masters” permissions. Default: - if not specified, it not be possible to issue kubectl commands against an imported cluster.
kubectl_security_group_id (Optional[str]) – A security group to use for kubectl execution. If not specified, the k8s endpoint is expected to be accessible publicly. Default: - k8s endpoint is expected to be accessible publicly
on_event_layer (Optional[ILayerVersion]) – 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. The handler expects the layer to include the following node_modules:: proxy-agent Default: - a layer bundled with this module.
open_id_connect_provider (Optional[IOpenIdConnectProvider]) – An Open ID Connect provider for this cluster that can be used to configure service accounts. You can either import an existing provider using iam.OpenIdConnectProvider.fromProviderArn, or create a new provider using new eks.OpenIdConnectProvider Default: - if not specified cluster.openIdConnectProvider and cluster.addServiceAccount will throw an error.
prune (Optional[bool]) – 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
security_group_ids (Optional[Sequence[str]]) – Additional security groups associated with this cluster. Default: - if not specified, no additional security groups will be considered in cluster.connections.
vpc (Optional[IVpc]) – The VPC in which this Cluster was created. Default: - if not specified cluster.vpc will throw an error
