--broker-node-group-info (structure)

Information about the broker nodes in the cluster.

BrokerAZDistribution -> (string)

The distribution of broker nodes across Availability Zones. This is an optional parameter. If you don’t specify it, Amazon MSK gives it the value DEFAULT. You can also explicitly set this parameter to the value DEFAULT. No other values are currently allowed.

Amazon MSK distributes the broker nodes evenly across the Availability Zones that correspond to the subnets you provide when you create the cluster.

ClientSubnets -> (list)

The list of subnets to connect to in the client virtual private cloud (VPC). AWS creates elastic network interfaces inside these subnets. Client applications use elastic network interfaces to produce and consume data. Client subnets can’t be in Availability Zone us-east-1e.


InstanceType -> (string)

The type of Amazon EC2 instances to use for Kafka brokers. The following instance types are allowed: kafka.m5.large, kafka.m5.xlarge, kafka.m5.2xlarge, kafka.m5.4xlarge, kafka.m5.12xlarge, and kafka.m5.24xlarge.

SecurityGroups -> (list)

The AWS security groups to associate with the elastic network interfaces in order to specify who can connect to and communicate with the Amazon MSK cluster. If you don’t specify a security group, Amazon MSK uses the default security group associated with the VPC.


StorageInfo -> (structure)

Contains information about storage volumes attached to MSK broker nodes.

EbsStorageInfo -> (structure)

EBS volume information.

VolumeSize -> (integer)

The size in GiB of the EBS volume for the data drive on each broker node.

Shorthand Syntax:


JSON Syntax:

  "BrokerAZDistribution": "DEFAULT",
  "ClientSubnets": ["string", ...],
  "InstanceType": "string",
  "SecurityGroups": ["string", ...],
  "StorageInfo": {
    "EbsStorageInfo": {
      "VolumeSize": integer

--client-authentication (structure)

Includes all client authentication related information.

Tls -> (structure)

Details for ClientAuthentication using TLS.

CertificateAuthorityArnList -> (list)

List of ACM Certificate Authority ARNs.


Shorthand Syntax:


JSON Syntax:

  "Tls": {
    "CertificateAuthorityArnList": ["string", ...]

--cluster-name (string)

The name of the cluster.

--configuration-info (structure)

Represents the configuration that you want MSK to use for the brokers in a cluster.

Arn -> (string)

ARN of the configuration to use.

Revision -> (long)

The revision of the configuration to use.

Shorthand Syntax:


JSON Syntax:

  "Arn": "string",
  "Revision": long

--encryption-info (structure)

Includes all encryption-related information.

EncryptionAtRest -> (structure)

The data-volume encryption details.

DataVolumeKMSKeyId -> (string)

The ARN of the AWS KMS key for encrypting data at rest. If you don’t specify a KMS key, MSK creates one for you and uses it.

EncryptionInTransit -> (structure)

The details for encryption in transit.

ClientBroker -> (string)

Indicates the encryption setting for data in transit between clients and brokers. The following are the possible values.

TLS means that client-broker communication is enabled with TLS only.

TLS_PLAINTEXT means that client-broker communication is enabled for both TLS-encrypted, as well as plaintext data.

PLAINTEXT means that client-broker communication is enabled in plaintext only.

The default value is TLS_PLAINTEXT.

InCluster -> (boolean)

When set to true, it indicates that data communication among the broker nodes of the cluster is encrypted. When set to false, the communication happens in plaintext.

The default value is true.

Shorthand Syntax:


JSON Syntax:

  "EncryptionAtRest": {
    "DataVolumeKMSKeyId": "string"
  "EncryptionInTransit": {
    "ClientBroker": "TLS"|"TLS_PLAINTEXT"|"PLAINTEXT",
    "InCluster": true|false

--enhanced-monitoring (string)

Specifies the level of monitoring for the MSK cluster. The possible values are DEFAULT, PER_BROKER, and PER_TOPIC_PER_BROKER.

Possible values:




--open-monitoring (structure)

The settings for open monitoring.

Prometheus -> (structure)

Prometheus settings.

JmxExporter -> (structure)

Indicates whether you want to enable or disable the JMX Exporter.

EnabledInBroker -> (boolean)

Indicates whether you want to enable or disable the JMX Exporter.

NodeExporter -> (structure)

Indicates whether you want to enable or disable the Node Exporter.

EnabledInBroker -> (boolean)

Indicates whether you want to enable or disable the Node Exporter.

Shorthand Syntax:


JSON Syntax:

  "Prometheus": {
    "JmxExporter": {
      "EnabledInBroker": true|false
    "NodeExporter": {
      "EnabledInBroker": true|false

--kafka-version (string)

The version of Apache Kafka.

    "S3": {
      "Bucket": "string",
      "Enabled": true|false,
      "Prefix": "string"

--number-of-broker-nodes (integer)

The number of broker nodes in the cluster.

--tags (map)

Create tags when creating the cluster.

key -> (string)

value -> (string)

Shorthand Syntax:


JSON Syntax:

{"string": "string"

--cli-input-json | --cli-input-yaml (string) Reads arguments from the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, those values will override the JSON-provided values. It is not possible to pass arbitrary binary values using a JSON-provided value as the string will be taken literally. This may not be specified along with --cli-input-yaml.

--generate-cli-skeleton (string) Prints a JSON skeleton to standard output without sending an API request. If provided with no value or the value input, prints a sample input JSON that can be used as an argument for --cli-input-json. Similarly, if provided yaml-input it will print a sample input YAML that can be used with --cli-input-yaml. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command.

--cli-auto-prompt (boolean) Automatically prompt for CLI input parameters.

See ‘aws help’ for descriptions of global parameters.


To create an Amazon MSK cluster

The following create-cluster example creates an MSK cluster named MessagingCluster with three broker nodes. A JSON file named brokernodegroupinfo.json specifies the three subnets over which you want Amazon MSK to distribute the broker nodes. This example doesn’t specify the monitoring level, so the cluster gets the DEFAULT level.

aws kafka create-cluster \
    --cluster-name "MessagingCluster" \
    --broker-node-group-info file://brokernodegroupinfo.json \
    --kafka-version "2.2.1" \
    --number-of-broker-nodes 3

Contents of brokernodegroupinfo.json:

    "InstanceType": "kafka.m5.xlarge",
    "BrokerAZDistribution": "DEFAULT",
    "ClientSubnets": [


    "ClusterArn": "arn:aws:kafka:us-west-2:123456789012:cluster/MessagingCluster/a1b2c3d4-5678-90ab-cdef-11111EXAMPLE-2",
    "ClusterName": "MessagingCluster",
    "State": "CREATING"

For more information, see Create an Amazon MSK Cluster in the Amazon Managed Streaming for Apache Kafka.


ClusterArn -> (string)

The Amazon Resource Name (ARN) of the cluster.

ClusterName -> (string)

The name of the MSK cluster.

State -> (string)

The state of the cluster. The possible states are CREATING, ACTIVE, and FAILED.
