パラメータ

このプラグインの設定で使用できるすべてのパラメータのリストは次のとおりです。

• name or plugin

  string required

  プラグイン名。この場合は aws-lambda 。

  • Kong Admin API、Kong Konnect API、宣言型構成、または decK ファイルを使用する場合、フィールドはnameです。
  • Kubernetes で KongPlugin オブジェクトを使用する場合、フィールドはpluginです。

• service.name or service.id

  string

  プラグインが対象とするサービス名または ID。最上位の /plugins エンドポイント. からプラグインをサービスに追加する場合は、これらのパラメータのいずれかを設定してください /services/{serviceName|Id}/plugins を使用する場合は必要ありません。

• route.name or route.id

  string

  プラグインがターゲットとするルート名または ID。最上位の /plugins エンドポイント. を通るルートにプラグインを追加する場合は、これらのパラメータのいずれかを設定してください /routes/{routeName|Id}/plugins を使用する場合は必要ありません。

• consumer.name or consumer.id

  string

  プラグインがターゲットとするコンシューマーの名前または ID。 最上位の /plugins エンドポイント. からコンシューマーにプラグインを追加する場合は、これらのパラメーターのいずれかを設定してください /consumers/{consumerName|Id}/pluginsを使用する場合は必要ありません。

• enabled

  boolean default: true

  このプラグインが適用されるかどうか。

• config

  record required
  • timeout

    number required default: 60000

    An optional timeout in milliseconds when invoking the function.

  • keepalive

    number required default: 60000

    An optional value in milliseconds that defines how long an idle connection lives before being closed.

  • aws_key

    string referenceable encrypted

    The AWS key credential to be used when invoking the function. The aws_key value is required if aws_secret is defined. If aws_key and aws_secret are not set, the plugin uses an IAM role inherited from the instance running Kong to authenticate. Can be symmetrically encrypted if using Kong Gateway and data encryption is configured.

  • aws_secret

    string referenceable encrypted

    The AWS secret credential to be used when invoking the function. The aws_secret value is required if aws_key is defined. If aws_key and aws_secret are not set, the plugin uses an IAM role inherited from the instance running Kong to authenticate. Can be symmetrically encrypted if using Kong Gateway and data encryption is configured.

  • aws_assume_role_arn

    string referenceable encrypted

    The target AWS IAM role ARN used to invoke the Lambda function. Typically this is used for a cross-account Lambda function invocation.

  • aws_role_session_name

    string default: kong

    The identifier of the assumed role session. It is used for uniquely identifying a session when the same target role is assumed by different principals or for different reasons. The role session name is also used in the ARN of the assumed role principle.

  • aws_region

    string

    The AWS region where the Lambda function is located. The plugin does not attempt to validate the supplied region name. If an invalid region name is provided, the plugin responds with an HTTP 500 Internal Server Error at runtime and logs a DNS resolution failure.

    The plugin will automatically detect the AWS region on runtime via AWS_REGION or AWS_DEFAULT_REGION environment variables when neither aws_region nor host is specified in plugin configuration. Using environment variables enables regionally distributed Kong cluster nodes to connect to the closest AWS region. If aws_region, host and environment variables have not been specified, the plugin responds with an HTTP 500 Internal Server Error at run-time.

  • function_name

    string

    The AWS Lambda function name to invoke. This may contain the function name only (my-function), the full ARN (arn:aws:lambda:us-west-2:123456789012:function:my-function) or a partial ARN (123456789012:function:my-function). You can also append a version number or alias to any of the formats.

  • qualifier

    string

    The Qualifier to use when invoking the function.

  • invocation_type

    string required default: RequestResponse Must be one of: RequestResponse, Event, DryRun

    The InvocationType to use when invoking the function. Available types are RequestResponse, Event, DryRun.

  • log_type

    string required default: Tail Must be one of: Tail, None

  • host

    string

    The host where the Lambda function is located. This value can point to a local Lambda server, allowing for easier debugging.

    Either aws_region or host must be provided.

  • port

    integer default: 443 between: 0 65535

    The TCP port that the plugin uses to connect to the server.

  • unhandled_status

    integer between: 100 999

    The response status code to use (instead of the default 200, 202, or 204) in the case of an Unhandled Function Error.

  • forward_request_method

    boolean default: false

    An optional value that defines whether the original HTTP request method verb is sent in the request_method field of the JSON-encoded request.

  • forward_request_uri

    boolean default: false

    An optional value that defines whether the original HTTP request URI is sent in the request_uri field of the JSON-encoded request. Request URI arguments (if any) are sent in the separate request_uri_args field of the JSON body.

  • forward_request_headers

    boolean default: false

    An optional value that defines whether the original HTTP request headers are sent as a map in the request_headers field of the JSON-encoded request.

  • forward_request_body

    boolean default: false

    An optional value that defines whether the request body is sent in the request_body field of the JSON-encoded request. If the body arguments can be parsed, they are sent in the separate request_body_args field of the request. The body arguments can be parsed for application/json, application/x-www-form-urlencoded, and multipart/form-data content types.

  • is_proxy_integration

    boolean default: false

    An optional value that defines whether the response format to receive from the Lambda to this format.

  • awsgateway_compatible

    boolean default: false

    An optional value that defines whether the plugin should wrap requests into the Amazon API gateway.

  • proxy_scheme

    string Must be one of: http, https

    As of Kong Gateway 2.8.0.0, this parameter is deprecated.
    
    If running Kong Gateway 2.7.x or earlier, the proxy_scheme value is required if proxy_url is defined. In 2.8.x or later versions, proxy_scheme is not required.

    An optional value that defines which HTTP scheme to use for connecting through the proxy server. The supported schemes are http and https.

  • proxy_url

    string

    An optional value that defines whether the plugin should connect through the given proxy server URL. Include the request scheme in the URL, which must be http. For example: http://my-proxy-server:3128.

    Kong Gateway uses HTTP tunneling via the CONNECT HTTP method so that no details of the AWS Lambda request are leaked to the proxy server.

  • skip_large_bodies

    boolean default: true

    An optional value that defines whether Kong should send large bodies that are buffered to disk. Note that enabling this option will have an impact on system memory depending on the number of requests simultaneously in flight at any given point in time and on the maximum size of each request. Also this option blocks all requests being handled by the nginx workers. That could be tens of thousands of other transactions that are not being processed. For small I/O operations, such a delay would generally not be problematic. In cases where the body size is in the order of MB, such a delay would cause notable interruptions in request processing. Given all of the potential downsides resulting from enabling this option, consider increasing the client_body_buffer_size value instead.

  • base64_encode_body

    boolean default: true
