2019/03/19 - Amazon Elastic Container Service for Kubernetes - 1 new 5 updated api methods
Changes Added support to control private/public access to the Kubernetes API-server endpoint
Updates an Amazon EKS cluster configuration. Your cluster continues to function during the update. The response output includes an update ID that you can use to track the status of your cluster update with the DescribeUpdate API operation.
Currently, the only cluster configuration changes supported are to enable or disable Amazon EKS public and private API server endpoints. For more information, see Amazon EKS Cluster Endpoint Access Control in the Amazon EKS User Guide .
Cluster updates are asynchronous, and they should finish within a few minutes. During an update, the cluster status moves to UPDATING (this status transition is eventually consistent). When the update is complete (either Failed or Successful ), the cluster status moves to Active .

string
[REQUIRED]
The name of the Amazon EKS cluster to update.
dict
An object representing an Amazon EKS cluster VPC configuration request.
subnetIds (list) --
Specify subnets for your Amazon EKS worker nodes. Amazon EKS creates cross-account elastic network interfaces in these subnets to allow communication between your worker nodes and the Kubernetes control plane.
(string) --
securityGroupIds (list) --
Specify one or more security groups for the cross-account elastic network interfaces that Amazon EKS creates to use to allow communication between your worker nodes and the Kubernetes control plane. If you do not specify a security group, the default security group for your VPC is used.
(string) --
endpointPublicAccess (boolean) --
Set this value to false to disable public access for 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. For more information, see Amazon EKS Cluster Endpoint Access Control in the Amazon EKS User Guide .
endpointPrivateAccess (boolean) --
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 will use the private VPC endpoint. The default value for this parameter is false , which disables private access for your Kubernetes API server. For more information, see Amazon EKS Cluster Endpoint Access Control in the Amazon EKS User Guide .
string
Unique, case-sensitive identifier that you provide to ensure the idempotency of the request.

Creates an Amazon EKS control plane.
The Amazon EKS control plane consists of control plane instances that run the Kubernetes software, like etcd and the API server. The control plane runs in an account managed by AWS, and the Kubernetes API is exposed via the Amazon EKS API server endpoint.
Amazon EKS worker nodes run in your AWS account and connect to your cluster's control plane via the Kubernetes API server endpoint and a certificate file that is created for your cluster.
The cluster control plane is provisioned across multiple Availability Zones and fronted by an Elastic Load Balancing Network Load Balancer. Amazon EKS also provisions elastic network interfaces in your VPC subnets to provide connectivity from the control plane instances to the worker nodes (for example, to support kubectl exec , logs , and proxy data flows).
After you create an Amazon EKS cluster, you must configure your Kubernetes tooling to communicate with the API server and launch worker nodes into your cluster. For more information, see Managing Cluster Authentication and Launching Amazon EKS Worker Nodes in the Amazon EKS User Guide .

dict
[REQUIRED]
The VPC configuration used by the cluster control plane. Amazon EKS VPC resources have specific requirements to work properly with Kubernetes. For more information, see Cluster VPC Considerations and Cluster Security Group Considerations in the Amazon EKS User Guide . You must specify at least two subnets. You may specify up to five security groups, but we recommend that you use a dedicated security group for your cluster control plane.

(string) --
securityGroupIds (list) --
