SelfManagedKafka

描述 SelfManagedKafka 事件源类型的对象。有关更多信息，请参阅《开发人员指南》中的AWS Lambda 与自行管理的 Apache Kafka 配合使用。AWS Lambda

AWS Serverless Application Model (AWS SAM) 在设置此事件类型时生成AWS::Lambda::EventSourceMapping资源。

要使用架构注册表，您需要为函数定义特定的 IAM 角色权限。有关所需配置的示例，请参阅使用 IAM 角色完成设置。

Self-managed Kafka 事件源

以下是 SelfManagedKafka 事件源类型的示例。

Events:
  SelfManagedKafkaEvent:
    Type: SelfManagedKafka
    Properties:
      BatchSize: 1000
      Enabled: true
      KafkaBootstrapServers:
        - abc.xyz.com:xxxx
      SourceAccessConfigurations:
        -  Type: BASIC_AUTH
           URI: arn:aws:secretsmanager:us-west-2:123456789012:secret:my-path/my-secret-name-1a2b3c
      Topics:
        - MyKafkaTopic

Self-managed 采用 OAuth 2.0 身份验证的 Kafka 事件源

以下示例使用进行 SASL/OAUTHBEARER身份验证。OAUTHBEARER_AUTH入口指向持有 OAuth 2.0 凭证的密钥，每个元数据条目都带有一个字面值，Lambda 会将其传递给您的一个或多个身份提供商。

Events:
  SelfManagedKafkaEvent:
    Type: SelfManagedKafka
    Properties:
      KafkaBootstrapServers:
        - abc.xyz.com:9092
      Topics:
        - MyKafkaTopic
      StartingPosition: LATEST
      ConsumerGroupId: consumergroup1
      SourceAccessConfigurations:
        - Type: OAUTHBEARER_AUTH
          URI: arn:aws:secretsmanager:us-west-2:123456789012:secret:my-path/my-oauth-secret-1a2b3c
        - Type: OAUTHBEARER_SCOPE
          URI: read write
        - Type: OAUTHBEARER_AUDIENCE
          URI: https://api.example.com
        - Type: SERVER_ROOT_CA_CERTIFICATE
          URI: arn:aws:secretsmanager:us-west-2:123456789012:secret:my-path/my-server-root-ca-cert-7p8q9r
        - Type: VPC_SUBNET
          URI: subnet:subnet-12345678
        - Type: VPC_SECURITY_GROUP
          URI: security_group:sg-12345678

Self-managed 采用 IAM 身份验证的 Kafka 事件源

以下示例使用 IAM 进行身份验证。该IAM_AUTH条目不带任何URI字段，因为 Lambda 使用函数执行角色的凭证对每个连接进行签名。向您的执行角色授予 Lambda 所需的集群权限，因为 AWS SAM 不会添加这些权限。

Events:
  SelfManagedKafkaEvent:
    Type: SelfManagedKafka
    Properties:
      KafkaBootstrapServers:
        - abc.xyz.com:9092
      Topics:
        - MyKafkaTopic
      StartingPosition: LATEST
      ConsumerGroupId: consumergroup1
      SourceAccessConfigurations:
        - Type: IAM_AUTH
        - Type: VPC_SUBNET
          URI: subnet:subnet-12345678
        - Type: VPC_SECURITY_GROUP
          URI: security_group:sg-12345678

Self-managed 采用 IAM 和 OAuth 2.0 身份验证的 Kafka 事件源

以下示例使用进行IAM_OAUTHBEARER_AUTH身份验证。此条目不包含任何URI字段，但您必须将其与经纪人URI所期望的受众群体配对。OAUTHBEARER_AUDIENCELambda 为执行角色请求一个短期的 Web 身份令牌，该令牌需要sts:GetWebIdentityToken许可，并且您的经纪人必须信任 AWS 发行者并接受受众价值。

Events:
  SelfManagedKafkaEvent:
    Type: SelfManagedKafka
    Properties:
      KafkaBootstrapServers:
        - abc.xyz.com:9092
      Topics:
        - MyKafkaTopic
      StartingPosition: LATEST
      ConsumerGroupId: consumergroup1
      SourceAccessConfigurations:
        - Type: IAM_OAUTHBEARER_AUTH
        - Type: OAUTHBEARER_AUDIENCE
          URI: kafka-cluster
        - Type: VPC_SUBNET
          URI: subnet:subnet-12345678
        - Type: VPC_SECURITY_GROUP
          URI: security_group:sg-12345678

Self-managed 带有 Kafka 事件源 AWS Glue 架构注册表

以下是使用 AWS Glue 架构注册表配置SelfManagedKafka的事件源类型的示例。

Events:
  SelfManagedKafkaEvent:
    Type: SelfManagedKafka
    Properties:
      KafkaBootstrapServers:
        - abc.xyz.com:9092
      Topics:
        - SchemaRegistryTestTopic
      StartingPosition: LATEST
      ProvisionedPollerConfig:
        MinimumPollers: 1
      SchemaRegistryConfig:
        SchemaRegistryURI: !Sub arn:${AWS::Partition}:glue:us-west-2:123456789012:registry/myregistry
        EventRecordFormat: JSON
        SchemaValidationConfigs:
          - Attribute: KEY
          - Attribute: VALUE
      SourceAccessConfigurations:
        - Type: VPC_SUBNET
          URI: subnet:subnet-12345678
        - Type: VPC_SECURITY_GROUP
          URI: security_group:sg-12345678
