--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 occupy the Availability Zone with ID use use1-az3.


InstanceType -> (string)

The type of Amazon EC2 instances to use for Apache 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.

ProvisionedThroughput -> (structure)

EBS volume provisioned throughput information.

--storage-mode (string)

This controls storage mode for supported storage tiers.

Possible values:



--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. The generated JSON skeleton is not stable between versions of the AWS CLI and there are no backwards compatibility guarantees in the JSON skeleton generated.

Global Options

--debug (boolean)

Turn on debug logging.

--endpoint-url (string)

Override command’s default URL with the given URL.

--no-verify-ssl (boolean)

By default, the AWS CLI uses SSL when communicating with AWS services. For each SSL connection, the AWS CLI will verify SSL certificates. This option overrides the default behavior of verifying SSL certificates.

--no-paginate (boolean)

Disable automatic pagination.

--output (string)

The formatting style for command output.

  • json

  • text

  • table

  • yaml

  • yaml-stream

--query (string)

A JMESPath query to use in filtering the response data.

--profile (string)

Use a specific profile from your credential file.

--region (string)

The region to use. Overrides config/env settings.

--version (string)

Display the version of this tool.

--color (string)

Turn on/off color output.

  • on

  • off

  • auto

--no-sign-request (boolean)

Do not sign requests. Credentials will not be loaded if this argument is provided.

--ca-bundle (string)

The CA certificate bundle to use when verifying SSL certificates. Overrides config/env settings.

--cli-read-timeout (int)

The maximum socket read time in seconds. If the value is set to 0, the socket read will be blocking and not timeout. The default value is 60 seconds.

--cli-connect-timeout (int)

The maximum socket connect time in seconds. If the value is set to 0, the socket connect will be blocking and not timeout. The default value is 60 seconds.

--cli-binary-format (string)

The formatting style to be used for binary blobs. The default format is base64. The base64 format expects binary blobs to be provided as a base64 encoded string. The raw-in-base64-out format preserves compatibility with AWS CLI V1 behavior and binary values must be passed literally. When providing contents from a file that map to a binary blob fileb:// will always be treated as binary and use the file contents directly regardless of the cli-binary-format setting. When using file:// the file contents will need to properly formatted for the configured cli-binary-format.

  • base64

  • raw-in-base64-out

--no-cli-pager (boolean)

Disable cli pager for output.

--cli-auto-prompt (boolean)

Automatically prompt for CLI input parameters.

--no-cli-auto-prompt (boolean)

Disable automatically prompt for CLI input parameters.



To use the following examples, you must have the AWS CLI installed and configured. See the Getting started guide in the AWS CLI User Guide for more information.

Unless otherwise stated, all examples have unix-like quotation rules. These examples will need to be adapted to your terminal’s quoting rules. See Using quotation marks with strings in the AWS CLI User Guide .

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",
