HC计算框架-terraform-aws-sns-to-cloudwatch-logs-lambda-PROSAGA-码农传奇

terraform-aws-sns-to-cloudwatch-logs-lambda is a Terraform module to provision a Lambda Function which routes SNS messages to CloudWatch Logs

Terraform versions >= 0.12, use module version >= "3.0.1" (See exception)
Terraform versions <= 0.11, use module version = "1.0.1"

Exception: if using var.aws_region to specify deployment region, use version = "2.0.1", until you can switch to provider aliases and explicit provider passing.

Terraform Module Features

This Module allows simple and rapid deployment

Creates Lambda function, Lambda Layer, IAM Policies, Triggers, and Subscriptions
Creates (or use existing) SNS Topic, CloudWatch Log Group and Log Group Stream
Options:
- Create CloudWatch Event to prevent Function hibernation
- Set Log Group retention period
Python function editable in repository and in Lambda UI
- Python dependencies packages in Lambda Layers zip
Optionally create custom Lambda Layer zip using build-lambda-layer-python
- Enables adding/changing dependencies
- Enables compiling for different version of Python
Breaking Changes in 3.0.0 - required to enable new Terraform 0.13 module arguments for_each, count, and depends_on
- The module’s internal AWS provider block has been removed
- var.aws_region has been removed and can’t be used to set a target region
- By default, modules inherit the region of the calling module’s Provider
- To specify alternate regions, use provider aliases and expicit provider passing
- Additional information on module considerations can be found in the docs for Provider Configuration in Modules with 0.13

This Lambda Function forwards subject & body of SNS messages to CloudWatch Log Group Stream

Enhances the value of CloudWatch Logs by enabling easy entry creation from any service, function and script that can send SNS notifications
Enables cloud-init, bootstraps and functions to easily write log entries to a centralized CloudWatch Log
Simplifies troubleshooting of solutions with decentralized logic
- scripts and functions spread across instances, Lambda and services
Easily add instrumentation to scripts: aws sns publish --topic-arn $TOPIC_ARN --message $LOG_ENTRY
- Use with IAM instance policy requires --region $AWS_REGION parameter

Usage

module "sns_logger" {
  source            = "robertpeteuil/sns-to-cloudwatch-logs-lambda/aws"
  version           = "3.0.1"     # Use with Terraform >= 0.12 (including 0.13)
  # version           = "1.0.1"   # Latest version for Terraform <= 0.11
  sns_topic_name    = "projectx-logging"
  log_group_name    = "projectx"
  log_stream_name   = "script-logs"
}

NOTE: Make sure you are using version pinning to avoid unexpected changes when the module is updated.
