AWS::MSK::Cluster
The AWS::MSK::Cluster resource creates an Amazon
MSK cluster. For more information, see What Is Amazon MSK? in the
Amazon MSK Developer Guide.
Syntax
To declare this entity in your AWS CloudFormation template, use the following syntax:
JSON
{ "Type" : "AWS::MSK::Cluster", "Properties" : { "BrokerNodeGroupInfo" :BrokerNodeGroupInfo, "ClientAuthentication" :ClientAuthentication, "ClusterName" :String, "ConfigurationInfo" :ConfigurationInfo, "EncryptionInfo" :EncryptionInfo, "EnhancedMonitoring" :String, "KafkaVersion" :String, "LoggingInfo" :LoggingInfo, "NumberOfBrokerNodes" :Integer, "OpenMonitoring" :OpenMonitoring, "Tags" :Json} }

Properties
BrokerNodeGroupInfo-
The setup to be used for brokers in the cluster.
Required: Yes
Type: BrokerNodeGroupInfo
Update requires: No interruption
ClientAuthentication-
Includes information related to client authentication.
Required: No
Type: ClientAuthentication

Specifies the level of monitoring for the MSK cluster. The possible values are
DEFAULT,PER_BROKER, andPER_TOPIC_PER_BROKER.Required: No
Type: String
Update requires: No interruption
KafkaVersion-
The version of Apache Kafka. You can use Amazon MSK to create clusters that use Apache Kafka versions 1.1.1 and 2.2.1.
Required: Yes
Type: String
Update requires: No interruption
LoggingInfo-
You can configure your MSK cluster to send broker logs to different destination types. This is a container for the configuration details related to broker logs.
Required: No
Type: LoggingInfo
Update requires: No interruption
NumberOfBrokerNodes-
The number of broker nodes you want in the Amazon MSK cluster. You can submit an update to increase the number of broker nodes in a cluster.
Required: Yes
Type: Integer
Update requires: No interruption
OpenMonitoring-
The settings for open monitoring.
Required: No
Type: OpenMonitoring
Update requires: No interruption
Tags-
A map of key:value pairs to apply to this resource. Both key and value are of type String.
Required: No
Type: Json
Update requires: Replacement
Return values
Ref
When you pass the logical ID of this resource to the intrinsic Ref function, Ref returns the Amazon MSK cluster ARN. For example:
REF MyTestCluster
For the Amazon MSK cluster MyTestCluster, Ref returns the ARN of the
cluster.
For more information about using the Ref function, see Ref.

Create Two MSK Clusters To Use With Apache MirrorMaker
This YAML shows how to set up two MSK clusters for MirrorMaker. It also sets up the Amazon VPC, subnets, security groups, and IAM roles that are necessary for this example. In addition, it creates an EC2 instance that has Apache Kafka, Java, and the Amazon CLI. You can use this EC2 instance to run Apache Kafka tools, including MirrorMaker. You must manually create the MirrorMaker configuration files.
