AWS::Lambda::WebFunctionRevision ServiceConfig

The service configuration for a web function revision, including execution role, timeout, VPC network access, concurrency, and telemetry settings.

Syntax

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

JSON

{
  "EgressNetworkConnectorArn" : String,
  "EnvironmentVariables" : {Key: Value, ...},
  "ExecutionRoleArn" : String,
  "MaxConcurrencyPerEnvironment" : Integer,
  "TelemetryConfig" : TelemetryConfig,
  "TimeoutSeconds" : Integer
}

YAML

  EgressNetworkConnectorArn: String
  EnvironmentVariables: 
    Key: Value
  ExecutionRoleArn: String
  MaxConcurrencyPerEnvironment: Integer
  TelemetryConfig: 
    TelemetryConfig
  TimeoutSeconds: Integer

Properties

EgressNetworkConnectorArn

The Amazon Resource Name (ARN) of the Lambda network connector that gives the web function access to resources in your VPC. You must specify the fully qualified ARN, including the connector version, which pins the revision to that version. If the network connector is deleted, invocations of revisions that reference it fail. Revisions that specify a network connector support only HomeRegion endpoints, not MultiRegion or PerRegion.
