Services or capabilities described in Amazon Web Services documentation might vary by Region. To see the differences applicable to the China Regions, see Getting Started with Amazon Web Services in China (PDF).

AWS::Bedrock::KnowledgeBase

Specifies a knowledge base as a resource in a top-level template. Minimally, you must specify the following properties:

  • Name – Specify a name for the knowledge base.

  • RoleArn – Specify the Amazon Resource Name (ARN) of the IAM role with permissions to invoke API operations on the knowledge base. For more information, see Create a service role for Knowledge base for Amazon Bedrock.

  • KnowledgeBaseConfiguration – Specify the embeddings configuration of the knowledge base. The following sub-properties are required:

    • Type – Specify the value VECTOR.

  • StorageConfiguration – Specify information about the vector store in which the data source is stored. The following sub-properties are required:

    • Type – Specify the vector store service that you are using.

    Note

    Redis Enterprise Cloud vector stores are currently unsupported in Amazon CloudFormation.

For more information about using knowledge bases in Amazon Bedrock, see Knowledge base for Amazon Bedrock.

See the Properties section below for descriptions of both the required and optional properties.
