AWS 2 Security Token Service (STS)

Since Camel 3.5

Only producer is supported

The AWS2 STS component supports assumeRole operation. AWS STS.

Prerequisites

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

The AWS2 STS component is not supported in OSGI

URI Format

aws2-sts://label[?options]

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

URI Options

The AWS 2 Security Token Service (STS) component supports 14 options, which are listed below.

Name Description Default Type

autoDiscoverClient (common)

Setting the autoDiscoverClient mechanism, if true, the component will look for a client instance in the registry automatically otherwise it will skip that checking.

true

boolean

configuration (producer)

Component configuration

STS2Configuration

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. There are 3 enums and the value can be one of: assumeRole, getSessionToken, getFederationToken

The region in which STS 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()

Usage

STS Producer operations

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

  • assumeRole

  • getSessionToken

  • getFedeationToken

Producer Examples

  • assumeRole: this operation will make an AWS user assume a different role temporary

from("direct:assumeRole")
    .setHeader(STS2Constants.ROLE_ARN, constant("arn:123"))
    .setHeader(STS2Constants.ROLE_SESSION_NAME, constant("groot"))
    .to("aws2-sts://test?stsClient=#amazonSTSClient&operation=assumeRole")
  • getSessionToken: this operation will return a temporary session token

from("direct:getSessionToken")
    .to("aws2-sts://test?stsClient=#amazonSTSClient&operation=getSessionToken")
  • getFederationToken: this operation will return a temporary federation token

from("direct:getFederationToken")
    .setHeader(STS2Constants.FEDERATED_NAME, constant("federation-account"))
    .to("aws2-sts://test?stsClient=#amazonSTSClient&operation=getSessionToken")

Automatic detection of StsClient client in registry

The component is capable of detecting the presence of an StsClient 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.

Using a POJO as body

Sometimes build an AWS Request can be complex, because of multiple options. We introduce the possibility to use a POJO as body. In AWS STS, as example for Assume Role request, you can do something like:

from("direct:createUser")
     .setBody(AssumeRoleRequest.builder().roleArn("arn:123").roleSessionName("groot").build())
    .to("aws2-sts://test?stsClient=#amazonSTSClient&operation=assumeRole&pojoRequest=true")

In this way you’ll pass the request directly without the need of passing headers and options specifically related to this operation.

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-sts</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-sts 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-sts-starter</artifactId>
  <version>x.x.x</version>
  <!-- use the same version as your Camel core version -->
</dependency>
