AWS Identity and Access Management (IAM)

Since Camel 3.1

Only producer is supported

The AWS2 IAM component supports create, run, start, stop and terminate AWS IAM instances.

Prerequisites

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

URI Format

aws2-iam://label[?options]

You can append query options to the URI in the following format:

?options=value&option2=value&…​

The AWS2 IAM component works on the aws-global region, and it has aws-global as the default region

Configuring Options

Camel components are configured on two separate levels:

  • component level

  • endpoint level

Configuring Component Options

At the component level, you set general and shared configurations that are, then, inherited by the endpoints. It is the highest configuration level.

For example, a component may have security settings, credentials for authentication, urls for network connection and so forth.

Some components only have a few options, and others may have many. Because components typically have pre-configured defaults that are commonly used, then you may often only need to configure a few options on a component; or none at all.

You can configure components using:

  • the Component DSL.

  • in a configuration file (application.properties, *.yaml files, etc).

  • directly in the Java code.

Configuring Endpoint Options

You usually spend more time setting up endpoints because they have many options. These options help you customize what you want the endpoint to do. The options are also categorized into whether the endpoint is used as a consumer (from), as a producer (to), or both.

Configuring endpoints is most often done directly in the endpoint URI as path and query parameters. You can also use the Endpoint DSL and DataFormat DSL as a type safe way of configuring endpoints and data formats in Java.

A good practice when configuring options is to use Property Placeholders.

Property placeholders provide a few benefits:

  • They help prevent using hardcoded urls, port numbers, sensitive information, and other settings.

  • They allow externalizing the configuration from the code.

  • They help the code to become more flexible and reusable.

The following two sections list all the options, firstly for the component followed by the endpoint.

Component Options

The AWS Identity and Access Management (IAM) component supports 22 options, which are listed below.

Name Description Default Type

configuration (producer)

Component configuration.

IAM2Configuration

iamClient (producer)

Autowired To use an existing configured AWS IAM client.

IamClient

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)

The operation to perform. You can configure a default operation on the component level, or the operation as part of the endpoint, or via a message header with the key CamelAwsIAMOperation.

Enum values:

  • listAccessKeys

  • createUser

  • deleteUser

  • getUser

  • listUsers

  • createAccessKey

  • deleteAccessKey

String

Usage

Static credentials, Default Credential Provider and Profile Credentials Provider

You have the possibility of avoiding the usage of explicit static credentials by specifying the useDefaultCredentialsProvider option and set it to true.

The order of evaluation for Default Credentials Provider is the following:

  • Java system properties - aws.accessKeyId and aws.secretKey.

  • Environment variables - AWS_ACCESS_KEY_ID and AWS_SECRET_ACCESS_KEY.

  • Web Identity Token from AWS STS.

  • The shared credentials and config files.

  • Amazon ECS container credentials - loaded from the Amazon ECS if the environment variable AWS_CONTAINER_CREDENTIALS_RELATIVE_URI is set.

  • Amazon EC2 Instance profile credentials.

You have also the possibility of using Profile Credentials Provider, by specifying the useProfileCredentialsProvider option to true and profileCredentialsName to the profile name.

Only one of static, default and profile credentials could be used at the same time.

For more information about this you can look at AWS credentials documentation

IAM Producer operations

Camel-AWS2 IAM component provides the following operation on the producer side:

  • listAccessKeys

  • createUser

  • deleteUser

  • listUsers

  • getUser

  • createAccessKey

  • deleteAccessKey

  • updateAccessKey

  • createGroup

  • deleteGroup

  • listGroups

  • addUserToGroup

  • removeUserFromGroup

Examples

Producer Examples

  • createUser: this operation will create a user in IAM

from("direct:createUser")
    .setHeader(IAM2Constants.USERNAME, constant("camel"))
    .to("aws2-iam://test?iamClient=#amazonIAMClient&operation=createUser")

  • deleteUser: this operation will delete a user in IAM

from("direct:deleteUser")
    .setHeader(IAM2Constants.USERNAME, constant("camel"))
    .to("aws2-iam://test?iamClient=#amazonIAMClient&operation=deleteUser")

  • listUsers: this operation will list the users in IAM

from("direct:listUsers")
    .to("aws2-iam://test?iamClient=#amazonIAMClient&operation=listUsers")

  • createGroup: this operation will add a group in IAM

from("direct:deleteUser")
    .setHeader(IAM2Constants.GROUP_NAME, constant("camel"))
    .to("aws2-iam://test?iamClient=#amazonIAMClient&operation=createGroup")

  • deleteGroup: this operation will delete a group in IAM

from("direct:deleteUser")
    .setHeader(IAM2Constants.GROUP_NAME, constant("camel"))
    .to("aws2-iam://test?iamClient=#amazonIAMClient&operation=deleteGroup")

  • listGroups: this operation will list the groups in IAM

from("direct:listUsers")
    .to("aws2-iam://test?iamClient=#amazonIAMClient&operation=listGroups")

Using a POJO as body

Sometimes building an AWS Request can be complex because of multiple options. We introduce the possibility to use a POJO as a body. In AWS IAM, there are multiple operations you can submit, as an example for Create User request, you can do something like:

from("direct:createUser")
     .setBody(CreateUserRequest.builder().userName("camel").build())
    .to("aws2-iam://test?iamClient=#amazonIAMClient&operation=createUser&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-iam</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-iam 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-iam-starter</artifactId>
