AWS MSK configuration

WARNING

This configuration will be deprecated in version 1.9 and removed in the future. In version 1.9 this configuration will be used to preload your clusters.

If one of your brokers in a cluster environment is located in an Amazon MSK cluster, you should specify saslMechanism, saslProtocol, saslJassConfig, and saslCallbackHandler for this broker, like this:

kouncil:
  clusters:
    - name: transaction-cluster
      brokers:
        - host: 192.10.0.1
          port: 9092
          saslMechanism: AWS_MSK_IAM
          saslProtocol: SASL_SSL
          saslJassConfig: software.amazon.msk.auth.iam.IAMLoginModule required awsProfileName="username";
          saslCallbackHandler: software.amazon.msk.auth.iam.IAMClientCallbackHandler
        - host: 192.10.0.2
          port: 9093
        - host: 192.10.0.3
          port: 9094

The above configuration uses IAM access to the Amazon MSK cluster, and you should provide AWS_SECRET_ACCESS_KEY and AWS_ACCESS_KEY_ID as environment variables to Kouncil. These two values should be generated for the user with access to the Amazon MSK cluster, and their user name should be provided in awsProfileName in the Kouncil configuration.
