When deployed in a VPC, the Lambda function will use ENIs in the VPC to access network resources and an Interface Endpoint will be created in the VPC for Amazon SNS. If an existing VPC is provided, thedeployVpcproperty cannot betrue. This usesec2.IVpcto allow clients to supply VPCs that exist outside the stack using theec2.Vpc.fromLookup()method.vpcProps?ec2.VpcPropsOptional user-provided properties to override the default properties for the new VPC.enableDnsHostnames,enableDnsSupport,natGatewaysandsubnetConfigurationare set by the pattern, so any values for those properties supplied here will be overridden. IfdeployVpcis nottruethen this property will be ignored.deployVpc?booleanWhether to create a new VPC based onvpcPropsinto which to deploy this pattern. Setting this to true will deploy the minimal, most private VPC to run the pattern:One isolated subnet in each Availability Zone used by the CDK programenableDnsHostnamesandenableDnsSupportwill both be set to trueIf this property istruethenexistingVpccannot be specified. Defaults tofalse.topicArnEnvironmentVariableName?stringOptional Name for the Lambda function environment variable set to the arn of the topic. Default: SNS_TOPIC_ARNtopicNameEnvironmentVariableName?stringOptional Name for the Lambda function environment variable set to the name of the topic. Default: SNS_TOPIC_NAMEenableEncryptionWithCustomerManagedKey?booleanIf no key is provided, this flag determines whether the SNS Topic is encrypted with a new CMK or an AWS managed key. This flag is ignored if any of the following are defined: topicProps.masterKey, encryptionKey or encryptionKeyProps.encryptionKey?kms.KeyAn optional, imported encryption key to encrypt the SNS Topic with.encryptionKeyProps?kms.KeyPropsOptional user provided properties to override the default properties for the KMS encryption key used to encrypt the SNS Topic with.Pattern PropertiesNameTypeDescriptionlambdaFunctionlambda.FunctionReturns an instance of the Lambda function created by the pattern.snsTopicsns.TopicReturns an instance of the SNS topic created by the pattern.vpc?ec2.IVpcReturns an interface on the VPC used by the pattern (if any). This may be a VPC created by the pattern or the VPC supplied to the pattern constructor.Default settingsOut of the box implementation of the Construct without any override will set the following defaults:AWS Lambda FunctionConfigure limited privilege access IAM role for Lambda function to access the Firehose Delivery StreamEnable reusing connections with Keep-Alive for NodeJs Lambda functionEnable X-Ray TracingSet Environment Variables(default) SNS_TOPIC_NAME(default) SNS_TOPIC_ARNAWS_NODEJS_CONNECTION_REUSE_ENABLED (for Node 10.x and higher functions)Amazon SNS TopicConfigure least privilege access permissions for SNS TopicEnable server-side encryption forSNS Topic using AWS managed KMS KeyEnforce encryption of data in transitArchitecture© Copyright Amazon.com, Inc. or its affiliates.
