AWS::Synthetics::Canary Code - AWS CloudFormation
SyntaxProperties

This is the new AWS CloudFormation Template Reference Guide. Please update your bookmarks and links. For help getting started with CloudFormation, see the AWS CloudFormation User Guide.

AWS::Synthetics::Canary Code

Use this structure to input your script code for the canary. This structure contains the Lambda handler with the location where the canary should start running the script. If the script is stored in an S3 bucket, the bucket name, key, and version are also included. If the script is passed into the canary directly, the script code is contained in the value of Script.

Syntax

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

JSON

{
  "BlueprintTypes" : [ String, ... ],
  "Dependencies" : [ Dependency, ... ],
  "Handler" : String,
  "S3Bucket" : String,
  "S3Key" : String,
  "S3ObjectVersion" : String,
  "Script" : String,
  "SourceLocationArn" : String
}

YAML

  BlueprintTypes: 
    - String
  Dependencies: 
    - Dependency
  Handler: String
  S3Bucket: String
  S3Key: String
  S3ObjectVersion: String
  Script: String
  SourceLocationArn: String

Properties

BlueprintTypes

BlueprintTypes are a list of templates that enable simplified canary creation. You can create canaries for common monitoring scenarios by providing only a JSON configuration file instead of writing custom scripts. multi-checks is the only supported value.

When you specify BlueprintTypes, the Handler field cannot be specified since the blueprint provides a pre-defined entry point.

Required: No

Type: Array of String

Maximum: 1

Update requires: No interruption

Dependencies

Property description not available.

Required: No

Type: Array of Dependency

Maximum: 1

Update requires: No interruption

Handler

The entry point to use for the source code when running the canary. For canaries that use the syn-python-selenium-1.0 runtime or a syn-nodejs.puppeteer runtime earlier than syn-nodejs.puppeteer-3.4, the handler must be specified as fileName.handler. For syn-python-selenium-1.1, syn-nodejs.puppeteer-3.4, and later runtimes, the handler can be specified as fileName.functionName, or you can specify a folder where canary scripts reside as folder/fileName.functionName.

This field is required when you don't specify BlueprintTypes and is not allowed when you specify BlueprintTypes.

Required: Conditional

Type: String

Pattern: ^(([0-9a-zA-Z_-]+(\/|\.))*[0-9A-Za-z_\\-]+(\.|::)[A-Za-z_][A-Za-z0-9_]*)?$

Minimum: 0

S3Bucket

If your canary script is located in S3, specify the bucket name here. The bucket must already exist.

Required: Conditional

Type: String

Update requires: No interruption

S3Key

The Amazon S3 key of your script. For more information, see Working with Amazon S3 Objects.

Required: Conditional

Type: String

SourceLocationArn
