## Example

```ts

// The values are placeholders you should change.
import { aws_msk as msk } from 'aws-cdk-lib';
const cfnConfigurationProps: msk.CfnConfigurationProps = {
  name: 'name',
  serverProperties: 'serverProperties',

  // the properties below are optional
  description: 'description',
  kafkaVersionsList: ['kafkaVersionsList'],
  latestRevision: {
    creationTime: 'creationTime',
    description: 'description',
    revision: 123,
  },
};
```

## Properties

- `description`: string — The description of the configuration.

- `kafkaVersionsList`: string[] — The [versions of Apache Kafka](https://docs.aws.amazon.com/msk/latest/developerguide/supported-kafka-versions.html) with which you can use this MSK configuration.

  When you update the `KafkaVersionsList` property, CloudFormation recreates a new configuration with the updated property before deleting the old configuration. Such an update requires a [resource replacement](https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/using-cfn-updating-stacks-update-behaviors.html#update-replacement) . To successfully update `KafkaVersionsList` , you must also update the `Name` property in the same operation.

  If your configuration is attached with any clusters created using the AWS Management Console or AWS CLI , you'll need to manually delete the old configuration from the console after the update completes.

  For more information, see [Can’t update KafkaVersionsList in MSK configuration](https://docs.aws.amazon.com/msk/latest/developerguide/troubleshooting.html#troubleshoot-kafkaversionslist-cfn-update-failure) in the *Amazon MSK Developer Guide* .

- `latestRevision`: [IResolvable](/cdk/api/v2/docs/aws-cdk-lib.IResolvable.html) | [CfnConfiguration.LatestRevisionProperty](/cdk/api/v2/docs/aws-cdk-lib.aws_msk.CfnConfiguration.LatestRevisionProperty.html) — Latest revision of the MSK configuration.

- `name`: string (required) — The name of the configuration.

  Configuration names are strings that match the regex "^[0-9A-Za-z][0-9A-Za-z-]{0,}$".

- `serverProperties`: string (required) — Contents of the `server.properties` file. When using the console, the SDK, or the AWS CLI , the contents of `server.properties` can be in plaintext.
