AWS::MSK::Cluster BrokerNodeGroupInfo

Describes the setup to be used for the broker nodes in the cluster.

Syntax

To declare this entity in your Amazon CloudFormation template, use the following syntax:

JSON

{ "BrokerAZDistribution" : String, "ClientSubnets" : [ String, ... ], "ConnectivityInfo" : ConnectivityInfo, "InstanceType" : String, "SecurityGroups" : [ String, ... ], "StorageInfo" : StorageInfo }

Properties

BrokerAZDistribution

This parameter is currently not in use.

Required: No

Type: String

Minimum: 6

Maximum: 9

Update requires: Replacement

ClientSubnets

The list of subnets to connect to in the client virtual private cloud (VPC). Amazon creates elastic network interfaces inside these subnets. Client applications use elastic network interfaces to produce and consume data.

If you use the US West (N. California) Region, specify exactly two subnets. For other Regions where Amazon MSK is available, you can specify either two or three subnets. The subnets that you specify must be in distinct Availability Zones. When you create a cluster, Amazon MSK distributes the broker nodes evenly across the subnets that you specify.

Client subnets can't occupy the Availability Zone with ID use1-az3.

SecurityGroups

The 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. If you specify security groups that were shared with you, you must ensure that you have permissions to them. Specifically, you need the ec2:DescribeSecurityGroups permission.
