AWS MSK Serverless

This page describes how to connect Lenses to an Amazon MSK Serverless cluster.

It is recommended to install the Agent on an EC2 instance or with EKS in the same VPC as your MSK Serverless cluster.

Security Groups

Enable communications between the Agent & the Amazon MSK Serverless cluster by opening the Amazon MSK Serverless cluster's security group in the AWS Console and add the IP address of your Agent installation.

IAM Policy

To authenticate the Agent & access resources within our MSK Serverless cluster, we'll need to create an IAM policy and apply that to the resource (EC2, EKS cluster, etc) running the Agent service. here is an example IAM policy with sufficient permissions which you can associate with the relevant IAM role:

{
    "Version": "2012-10-17",
    "Statement": [
        {
            "Effect": "Allow",
            "Action": [
                "kafka-cluster:Connect",
                "kafka-cluster:AlterCluster",
                "kafka-cluster:DescribeCluster"
            ],
            "Resource": "arn:aws:kafka:[region]:[aws_account_id]:cluster/[cluster_name]/[cluster_uuid]/*"
        },
        {
            "Effect": "Allow",
            "Action": [
                "kafka-cluster:DescribeTopic",
                "kafka-cluster:CreateTopic",
                "kafka-cluster:WriteData",
                "kafka-cluster:ReadData"
            ],
            "Resource": "arn:aws:kafka:[region]:[aws_account_id]:topic/[cluster_name]/[cluster_uuid]/*"
        },
        {
            "Effect": "Allow",
            "Action": [
                "kafka-cluster:AlterGroup",
                "kafka-cluster:DescribeGroup"
            ],
            "Resource": "arn:aws:kafka:[region]:[aws_account_id]:group/[cluster_name]/[cluster_uuid]/*"
        }
    ]
}

MSK Serverless IAM to be used after cluster creation. Update this IAM policy with the relevant ARN.

Select your MSK endpoint

Click your MSK Serverless Cluster in the MSK console and select View Client Information page to check the bootstrap server endpoint.

Configure Provisioning

provisioning.yaml

kafka:
  tags: ["optional-tag"]
  name: Kafka
  configuration:
    kafkaBootstrapServers:
      value:
       - SASL_SSL://your.kafka.broker.0:9098
       - SASL_SSL://your.kafka.broker.1:9098
    protocol: SASL_SSL
    saslMechanism: 
      value: AWS_MSK_IAM
    saslJaasConfig:
      value: software.amazon.msk.auth.iam.IAMLoginModule required;
    additionalProperties:
      value:
        sasl.client.callback.handler.class: "software.amazon.msk.auth.iam.IAMClientCallbackHandle

SQL Processor Configurations

To enable the creation of SQL Processors that create consumer groups, you need to add the following statement in your IAM policy:

{
  "Action": [
    "kafka-cluster:*Topic*",
    "kafka-cluster:WriteData",
    "kafka-cluster:ReadData"
  ],
  "Resource": "arn:aws:kafka:[region]:[aws_account_id]:cluster/[cluster_name]/[cluster_uuid]/*"
}

Update the placeholders in the IAM policy based on the relevant MSK Serverless cluster ARN.

To integrate with the AWS Glue Schema Registry, you also need to add the following statement for the registries and schemas in your IAM policy:

{
  "Action": [
    "kafka-cluster:*Group*"
  ],
  "Resource": "arn:aws:kafka:[region]:[aws_account_id]:cluster/[cluster_name]/[cluster_uuid]/*"
}

Update the placeholders in the IAM policy based on the relevant MSK Serverless cluster ARN.

To integrate with the AWS Glue Schema Registry, you also need to modify the security policy for the registry and schemas, which results in additional functions within it:

{
  "Action": [
    "glue:DeregisterDataPreview",
    "glue:ListRegistries",
    "glue:CreateRegistry",
    "glue:RegisterSchemaVersion",
    "glue:GetRegistry",
    "glue:UpdateRegistry",
    "glue:ListSchemas",
    "glue:DeleteRegistry",
    "glue:GetSchema",
    "glue:CreateSchema",
    "glue:ListSchemaVersions",
    "glue:GetSchemaVersion",
    "glue:UpdateSchema",
    "glue:DeleteSchemaVersions"
  ],
  "Resource": [
    "arn:aws:glue:[region]:[aws_account_id]:registry/*",
    "arn:aws:glue:[region]:[aws_account_id]:schema/*"
  ]
}

More details about how IAM works with MSK Serverless can be found in the documentation: MSK Serverless

Limitations

When using the Agent with MSK Serverless:

The agent does not receive Prometheus-compatible metrics from the brokers because they are not exported outside of CloudWatch.
The agent does not configure quotas and ACLs because MSK Serveless does not allow this.
