public class AWSAppMeshClient
extends AmazonWebServiceClient
implements AWSAppMesh

Client for accessing AWS App Mesh. All service calls made using this client are blocking, and will not return until the service call completes.

AWS App Mesh is a service mesh based on the Envoy proxy that makes it easy to monitor and control containerized microservices. App Mesh standardizes how your microservices communicate, giving you end-to-end visibility and helping to ensure high-availability for your applications.

App Mesh gives you consistent visibility and network traffic controls for every microservice in an application. You can use App Mesh with Amazon ECS (using the Amazon EC2 launch type), Amazon EKS, and Kubernetes on AWS.

App Mesh supports containerized microservice applications that use service discovery naming for their components. To use App Mesh, you must have a containerized application running on Amazon EC2 instances, hosted in either Amazon ECS, Amazon EKS, or Kubernetes on AWS. For more information about service discovery on Amazon ECS, see Service Discovery in the Amazon Elastic Container Service Developer Guide. Kubernetes kube-dns is supported. For more information, see DNS for Services and Pods in the Kubernetes documentation.

public static AWSAppMeshClientBuilder builder()

createMesh

public CreateMeshResult createMesh(CreateMeshRequest request)

Creates a new service mesh. A service mesh is a logical boundary for network traffic between the services that reside within it.

After you create your service mesh, you can create virtual nodes, virtual routers, and routes to distribute traffic between the applications in your mesh.

Specified by:

createMesh in interface AWSAppMesh

Parameters:

createMeshRequest -

Returns:

Result of the CreateMesh operation returned by the service.

Throws:

BadRequestException - The request syntax was malformed. Check your request syntax and try again.

ConflictException - The request contains a client token that was used for a previous update resource call with different specifications. Try the request again with a new client token.

ForbiddenException - You do not have permissions to perform this action.

InternalServerErrorException - The request processing has failed because of an unknown error, exception, or failure.

LimitExceededException - You have exceeded a service limit for your account. For more information, see Service Limits in the AWS App Mesh User Guide.

NotFoundException - The specified resource does not exist. Check your request syntax and try again.

ServiceUnavailableException - The request has failed due to a temporary failure of the service.

TooManyRequestsException - The maximum request rate permitted by the App Mesh APIs has been exceeded for your account. For best results, use an increasing or variable sleep interval between requests.

See Also:

AWS API Documentation

createRoute

public CreateRouteResult createRoute(CreateRouteRequest request)

Creates a new route that is associated with a virtual router.

You can use the prefix parameter in your route specification for path-based routing of requests. For example, if your virtual router service name is my-service.local, and you want the route to match requests to my-service.local/metrics, then your prefix should be /metrics.

If your route matches a request, you can distribute traffic to one or more target virtual nodes with relative weighting.

Specified by:

createRoute in interface AWSAppMesh

Parameters:

createRouteRequest -

Returns:

Result of the CreateRoute operation returned by the service.

Throws:

BadRequestException - The request syntax was malformed. Check your request syntax and try again.

ConflictException - The request contains a client token that was used for a previous update resource call with different specifications. Try the request again with a new client token.

ForbiddenException - You do not have permissions to perform this action.

InternalServerErrorException - The request processing has failed because of an unknown error, exception, or failure.

LimitExceededException - You have exceeded a service limit for your account. For more information, see Service Limits in the AWS App Mesh User Guide.

NotFoundException - The specified resource does not exist. Check your request syntax and try again.

ServiceUnavailableException - The request has failed due to a temporary failure of the service.

TooManyRequestsException - The maximum request rate permitted by the App Mesh APIs has been exceeded for your account. For best results, use an increasing or variable sleep interval between requests.

createVirtualNode

public CreateVirtualNodeResult createVirtualNode(CreateVirtualNodeRequest request)

Creates a new virtual node within a service mesh.

A virtual node acts as logical pointer to a particular task group, such as an Amazon ECS service or a Kubernetes deployment. When you create a virtual node, you must specify the DNS service discovery name for your task group.

Any inbound traffic that your virtual node expects should be specified as a listener. Any outbound traffic that your virtual node expects to reach should be specified as a backend.

The response metadata for your new virtual node contains the arn that is associated with the virtual node. Set this value (either the full ARN or the truncated resource name, for example, mesh/default/virtualNode/simpleapp, as the APPMESH_VIRTUAL_NODE_NAME environment variable for your task group's Envoy proxy container in your task definition or pod spec. This is then mapped to the node.id and node.cluster Envoy parameters.

If you require your Envoy stats or tracing to use a different name, you can override the node.cluster value that is set by APPMESH_VIRTUAL_NODE_NAME with the APPMESH_VIRTUAL_NODE_CLUSTER environment variable.

Specified by:

createVirtualNode in interface AWSAppMesh

Parameters:

createVirtualNodeRequest -

Returns:

Result of the CreateVirtualNode operation returned by the service.

Throws:

BadRequestException - The request syntax was malformed. Check your request syntax and try again.

ConflictException - The request contains a client token that was used for a previous update resource call with different specifications. Try the request again with a new client token.

ForbiddenException - You do not have permissions to perform this action.

InternalServerErrorException - The request processing has failed because of an unknown error, exception, or failure.

LimitExceededException - You have exceeded a service limit for your account. For more information, see Service Limits in the AWS App Mesh User Guide.

NotFoundException - The specified resource does not exist. Check your request syntax and try again.

ServiceUnavailableException - The request has failed due to a temporary failure of the service.

TooManyRequestsException - The maximum request rate permitted by the App Mesh APIs has been exceeded for your account. For best results, use an increasing or variable sleep interval between requests.

getCachedResponseMetadata

public ResponseMetadata getCachedResponseMetadata(AmazonWebServiceRequest request)

Returns additional metadata for a previously executed successful, request, typically used for debugging issues where a service isn't acting as expected. This data isn't considered part of the result data returned by an operation, so it's available through this separate, diagnostic interface.

Response metadata is only cached for a limited period of time, so if you need to access this extra diagnostic information for an executed request, you should use this method to retrieve it as soon as possible after executing the request.

Specified by:

getCachedResponseMetadata in interface AWSAppMesh

Parameters:

request - The originally executed request

Returns:

The response metadata for the specified request, or null if none is available.
