public class AmazonEKSAsyncClient
extends AmazonEKSClient
implements AmazonEKSAsync

Client for accessing Amazon EKS asynchronously. Each asynchronous method will return a Java Future object representing the asynchronous operation; overloads which accept an AsyncHandler can be used to receive notification when an asynchronous operation completes.

Amazon Elastic Container Service for Kubernetes (Amazon EKS) is a managed service that makes it easy for you to run Kubernetes on AWS without needing to stand up or maintain your own Kubernetes control plane. Kubernetes is an open-source system for automating the deployment, scaling, and management of containerized applications.

Amazon EKS runs three Kubernetes control plane instances across three Availability Zones to ensure high availability. Amazon EKS automatically detects and replaces unhealthy control plane instances, and it provides automated version upgrades and patching for them.

Amazon EKS is also integrated with many AWS services to provide scalability and security for your applications, including the following:

• Elastic Load Balancing for load distribution

• IAM for authentication

• Amazon VPC for isolation

Amazon EKS runs up to date versions of the open-source Kubernetes software, so you can use all the existing plugins and tooling from the Kubernetes community. Applications running on Amazon EKS are fully compatible with applications running on any standard Kubernetes environment, whether running in on-premises data centers or public clouds. This means that you can easily migrate any standard Kubernetes application to Amazon EKS without any code modification required.

Method Detail

asyncBuilder

public static AmazonEKSAsyncClientBuilder asyncBuilder()

getExecutorService

public ExecutorService getExecutorService()

Returns the executor service used by this client to execute async requests.

Returns:

The executor service used by this client to execute async requests.

createClusterAsync

public Future<CreateClusterResult> createClusterAsync(CreateClusterRequest request)

Description copied from interface: AmazonEKSAsync

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 Nodesin the Amazon EKS User Guide.

Specified by:

createClusterAsync in interface AmazonEKSAsync

Returns:

A Java Future containing the result of the CreateCluster operation returned by the service.

asyncHandler - Asynchronous callback handler for events in the lifecycle of the request. Users can provide an implementation of the callback methods in this interface to receive notification of successful or unsuccessful completion of the operation.

Returns:

A Java Future containing the result of the CreateCluster operation returned by the service.

deleteClusterAsync

public Future<DeleteClusterResult> deleteClusterAsync(DeleteClusterRequest request)

Description copied from interface: AmazonEKSAsync

Deletes the Amazon EKS cluster control plane.

If you have active services in your cluster that are associated with a load balancer, you must delete those services before deleting the cluster so that the load balancers are deleted properly. Otherwise, you can have orphaned resources in your VPC that prevent you from being able to delete the VPC. For more information, see Deleting a Cluster in the Amazon EKS User Guide.

Returns:

A Java Future containing the result of the DeleteCluster operation returned by the service.

shutdown

public void shutdown()

Shuts down the client, releasing all managed resources. This includes forcibly terminating all pending asynchronous service calls. Clients who wish to give pending asynchronous service calls time to complete should call getExecutorService().shutdown() followed by getExecutorService().awaitTermination() prior to calling this method.
