Chapter 11. AWS SNS Sink

Send message to an Amazon Simple Notification Service (SNS) topic.

11.1. Authentication methods
Copy link

In this Kamelet you can avoid using 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 can also use the Profile Credentials Provider, by setting the useProfileCredentialsProvider option to true and profileCredentialsName to the profile name.

Only one of access key/secret key or default credentials provider could be used

For more information, see the AWS credentials documentation

11.2. Optional Headers

In the Kamelet you can optionally set the following header:

  • subject / ce-subject: the subject of the message

11.5.1.2. Running a route with JBang
Copy link

Suppose you have a file named route.yaml with this content: 

- route:
    from:
      uri: "kamelet:timer-source"
      parameters:
        period: 10000
        message: 'test'
      steps:
        - to:
            uri: "kamelet:log-sink"

You can now run it directly through the following command. 

camel run route.yaml
