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.

The AWS2 IAM component is not supported in OSGI

URI Format

aws2-iam://label[?options]

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

URI Options

The AWS Identity and Access Management (IAM) component supports 16 options, which are listed below.

Name Description Default Type

configuration (producer)

Component configuration

IAM2Configuration

iamClient (producer)

Autowired To use a existing configured AWS IAM as 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. There are 13 enums and the value can be one of: listAccessKeys, createUser, deleteUser, getUser, listUsers, createAccessKey, deleteAccessKey, updateAccessKey, createGroup, deleteGroup, listGroups, addUserToGroup, removeUserFromGroup

IAM2Operations

overrideEndpoint (producer)

Set the need for overidding the endpoint. This option needs to be used in combination with uriEndpointOverride option

false

boolean

pojoRequest (producer)

If we want to use a POJO request as body or not

false

boolean

proxyHost (producer)

To define a proxy host when instantiating the IAM client

String

proxyPort (producer)

To define a proxy port when instantiating the IAM client

Integer

proxyProtocol (producer)

To define a proxy protocol when instantiating the IAM client. There are 2 enums and the value can be one of: HTTP, HTTPS

HTTPS

Protocol

region (producer)

The region in which IAM 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()

aws-global

String

trustAllCertificates (producer)

If we want to trust all certificates in case of overriding the endpoint

false

boolean

uriEndpointOverride (producer)

Set the overriding uri endpoint. This option needs to be used in combination with overrideEndpoint option

false

boolean

autowiredEnabled (advanced)

Whether autowiring is enabled. This is used for automatic autowiring options (the option must be marked as autowired) by looking up in the registry to find if there is a single instance of matching type, which then gets configured on the component. This can be used for automatic configuring JDBC data sources, JMS connection factories, AWS Clients, etc.

true

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

Static credentials vs Default Credential Provider

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

  • 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.

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

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 build an AWS Request can be complex, because of multiple options. We introduce the possibility to use a POJO as 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>
  <version>x.x.x</version>
  <!-- use the same version as your Camel core version -->
