AWS 2 ECS Component

Since Camel 3.1

Since Camel 3.1

Only producer is supported

The ECS component supports create, delete, describe and list AWS ECS clusters instances.

Prerequisites

You must have a valid Amazon Web Services developer account, and be signed up to use Amazon ECS. More information is available at Amazon ECS.

The AWS2 ECS component is not supported in OSGI

URI Format

aws2-ecs://label[?options]

You can append query options to the URI in the following format, ?options=value&option2=value&…​

URI Options

The AWS 2 ECS component supports 6 options, which are listed below.

Name Description Default Type

accessKey (producer)

Amazon AWS Access Key

String

lazyStartProducer (producer)

Whether the producer should be started lazy (on the first message). By starting lazy you can use this to allow CamelContext and routes to startup in situations where a producer may otherwise fail during starting and cause the route to fail being started. By deferring this startup to be lazy then the startup failure can be handled during routing messages via Camel’s routing error handlers. Beware that when the first message is processed then creating and starting the producer may take a little time and prolong the total processing time of the processing.

false

boolean

region (producer)

The region in which ECS client needs to work

String

secretKey (producer)

Amazon AWS Secret Key

String

basicPropertyBinding (advanced)

Whether the component should use basic property binding (Camel 2.x) or the newer property binding with additional capabilities

false

boolean

configuration (advanced)

The AWS ECS default configuration

ECS2Configuration

The AWS 2 ECS endpoint is configured using URI syntax:

aws2-ecs:label

with the following path and query parameters:

Path Parameters (1 parameters):

Name Description Default Type

label

Required Logical name

String

Query Parameters (11 parameters):

Name Description Default Type

accessKey (producer)

Amazon AWS Access Key

String

ecsClient (producer)

To use a existing configured AWS ECS as client

EcsClient

lazyStartProducer (producer)

Whether the producer should be started lazy (on the first message). By starting lazy you can use this to allow CamelContext and routes to startup in situations where a producer may otherwise fail during starting and cause the route to fail being started. By deferring this startup to be lazy then the startup failure can be handled during routing messages via Camel’s routing error handlers. Beware that when the first message is processed then creating and starting the producer may take a little time and prolong the total processing time of the processing.

false

boolean

operation (producer)

Required The operation to perform. The value can be one of: listClusters, describeCluster, createCluster, deleteCluster

ECS2Operations

proxyHost (producer)

To define a proxy host when instantiating the ECS client

String

proxyPort (producer)

To define a proxy port when instantiating the ECS client

Integer

proxyProtocol (producer)

To define a proxy protocol when instantiating the ECS client. The value can be one of: HTTP, HTTPS

HTTPS

Protocol

region (producer)

The region in which ECS client needs to work. When using this parameter, the configuration will expect the lowercase name of the region (for example ap-east-1) You’ll need to use the name Region.EU_WEST_1.id()

String

secretKey (producer)

Amazon AWS Secret Key

String

basicPropertyBinding (advanced)

Whether the endpoint should use basic property binding (Camel 2.x) or the newer property binding with additional capabilities

false

boolean

synchronous (advanced)

Sets whether synchronous processing should be strictly used, or Camel is allowed to use asynchronous processing (if supported).

false

boolean

Required ECS component options

You have to provide the amazonECSClient in the Registry or your accessKey and secretKey to access the Amazon ECS service.

Usage

Message headers evaluated by the ECS producer

Header Type Description

CamelAwsECSMaxResults

Integer

The limit number of results while listing clusters

CamelAwsECSOperation

String

The operation we want to perform

CamelAwsECSClusterName

String

The cluster name

ECS Producer operations

Camel-AWS ECS component provides the following operation on the producer side:

  • listClusters

  • createCluster

  • describeCluster

  • deleteCluster

Producer Examples

  • listClusters: this operation will list the available clusters in ECS

from("direct:listClusters")
    .to("aws2-ecs://test?ecsClient=#amazonEcsClient&operation=listClusters")

Automatic detection of EcsClient client in registry

The component is capable of detecting the presence of an EcsClient bean into the registry. If it’s the only instance of that type it will be used as client and you won’t have to define it as uri parameter. This may be really useful for smarter configuration of the endpoint.

Dependencies

Maven users will need to add the following dependency to their pom.xml.

pom.xml

<dependency>
    <groupId>org.apache.camel</groupId>
    <artifactId>camel-aws2-ecs</artifactId>
    <version>${camel-version}</version>
</dependency>

where ${camel-version} must be replaced by the actual version of Camel.

Spring Boot Auto-Configuration

When using aws2-ecs with Spring Boot make sure to use the following Maven dependency to have support for auto configuration:

<dependency>
  <groupId>org.apache.camel.springboot</groupId>
  <artifactId>camel-aws2-ecs-starter</artifactId>
  <version>x.x.x</version>
  <!-- use the same version as your Camel core version -->
</dependency>

The component supports 14 options, which are listed below.
