VpcConfigRequest
An object representing the VPC configuration to use for an Amazon EKS cluster.
Types
Properties
Specifies the control plane egress routing mode for the cluster. If the cluster is set to AWS_MANAGED, Amazon EKS manages the egress path from the control plane and you don't need to configure NAT gateways or other routing infrastructure for control plane traffic. If the cluster is set to CUSTOMER_ROUTED, you manage the egress path from the control plane in your VPC subnets. You are responsible for ensuring that the control plane can reach required endpoints such as webhook servers and OIDC providers. The default value is AWS_MANAGED. Once set to CUSTOMER_ROUTED, this setting cannot be changed back to AWS_MANAGED on the same cluster.
Set this value to true to enable private access for your cluster's Kubernetes API server endpoint. If you enable private access, Kubernetes API requests from within your cluster's VPC use the private VPC endpoint. The default value for this parameter is false, which disables private access for your Kubernetes API server. If you disable private access and you have nodes or Fargate pods in the cluster, then ensure that publicAccessCidrs includes the necessary CIDR blocks for communication with the nodes or Fargate pods. For more information, see Cluster API server endpoint in the Amazon EKS User Guide.
Set this value to false to disable public access to your cluster's Kubernetes API server endpoint. If you disable public access, your cluster's Kubernetes API server can only receive requests from within the cluster VPC. The default value for this parameter is true, which enables public access for your Kubernetes API server. The endpoint domain name and IP address family depends on the value of the ipFamily for the cluster. For more information, see Cluster API server endpoint in the Amazon EKS User Guide.
The CIDR blocks that are allowed access to your cluster's public Kubernetes API server endpoint. Communication to the endpoint from addresses outside of the CIDR blocks that you specify is denied. The default value is 0.0.0.0/0 and additionally ::/0 for dual-stack IPv6 clusters. If you've disabled private endpoint access, make sure that you specify the necessary CIDR blocks for every node and Fargate Pod in the cluster. For more information, see Cluster API server endpoint in the Amazon EKS User Guide.
Specify one or more security groups for the cross-account elastic network interfaces that Amazon EKS creates to use that allow communication between your nodes and the Kubernetes control plane. If you don't specify any security groups, then familiarize yourself with the difference between Amazon EKS defaults for clusters deployed with Kubernetes. For more information, see Amazon EKS security group considerations in the Amazon EKS User Guide.
