[ aws . kafka ]



Returns a list of all the MSK clusters in the current Region.

See also: AWS API Documentation

See ‘aws help’ for descriptions of global parameters.

list-clusters is a paginated operation. Multiple API calls may be issued in order to retrieve the entire data set of results. You can disable pagination by providing the --no-paginate argument. When using --output text and the --query argument on a paginated response, the --query argument must extract data from the results of the following query expressions: ClusterInfoList


[--cluster-name-filter <value>]
[--cli-input-json | --cli-input-yaml]
[--starting-token <value>]
[--page-size <value>]
[--max-items <value>]
[--generate-cli-skeleton <value>]
[--cli-auto-prompt <value>]


--cluster-name-filter (string)

Specify a prefix of the name of the clusters that you want to list. The service lists all the clusters whose names start with this prefix.

--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.

--starting-token (string)

A token to specify where to start paginating. This is the NextToken from a previously truncated response.

For usage examples, see Pagination in the AWS Command Line Interface User Guide .

--page-size (integer)

The size of each page to get in the AWS service call. This does not affect the number of items returned in the command’s output. Setting a smaller page size results in more calls to the AWS service, retrieving fewer items in each call. This can help prevent the AWS service calls from timing out.

For usage examples, see Pagination in the AWS Command Line Interface User Guide .

--max-items (integer)

The total number of items to return in the command’s output. If the total number of items available is more than the value specified, a NextToken is provided in the command’s output. To resume pagination, provide the NextToken value in the starting-token argument of a subsequent command. Do not use the NextToken response element directly outside of the AWS CLI.

For usage examples, see Pagination in the AWS Command Line Interface User Guide .

--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.

For more information, see Listing Amazon MSK Clusters in the Amazon Managed Streaming for Apache Kafka Developer Guide.


ClusterInfoList -> (list)

Information on each of the MSK clusters in the response.


Returns information about a cluster.

ActiveOperationArn -> (string)

Arn of active cluster operation.

BrokerNodeGroupInfo -> (structure)

Information about the broker nodes.

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)

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.

EnhancedMonitoring -> (string)

Specifies which metrics are gathered for the MSK cluster. This property has three possible values: DEFAULT, PER_BROKER, and PER_TOPIC_PER_BROKER. For a list of the metrics associated with each of these three levels of monitoring, see Monitoring .
