Step 2: Create an IAM role granting access to create topics on the Amazon MSK cluster - Amazon Managed Streaming for Apache Kafka

Step 2: Create an IAM role granting access to create topics on the Amazon MSK cluster

In this step, you perform two tasks. The first task is to create an IAM policy that grants access to create topics on the cluster and to send data to those topics. The second task is to create an IAM role and associate this policy with it. In a later step, you create a client machine that assumes this role and uses it to create a topic on the cluster and to send data to that topic.

To create an IAM policy that makes it possible to create topics and write to them

  1. Open the IAM console at https://console.aws.amazon.com/iam/.

  2. On the navigation pane, choose Policies.

  3. Choose Create Policy.

  4. Choose the JSON tab, then replace the JSON in the editor window with the following JSON.

    Replace region with the code of the AWS region where you created your cluster. Replace Account-ID with your account ID. Replace MSKTutorialCluster with the name of your cluster.

    {
    "Version": "2012-10-17",
    "Statement": [
        {
            "Effect": "Allow",
            "Action": [
                "kafka-cluster:Connect",
                "kafka-cluster:AlterCluster",
                "kafka-cluster:DescribeCluster"
            ],
            "Resource": [
                "arn:aws:kafka:region:Account-ID:cluster/MSKTutorialCluster/*"
            ]
        },
        {
            "Effect": "Allow",
            "Action": [
                "kafka-cluster:*Topic*",
                "kafka-cluster:WriteData",
                "kafka-cluster:ReadData"
            ],
            "Resource": [
                "arn:aws:kafka:region:Account-ID:topic/MSKTutorialCluster/*"
            ]
        },
        {
            "Effect": "Allow",
            "Action": [
                "kafka-cluster:AlterGroup",
                "kafka-cluster:DescribeGroup"
            ],
            "Resource": [
                "arn:aws:kafka:region:Account-ID:group/MSKTutorialCluster/*"
            ]
        }
    ]
}
