bmukum/cloudwatch-slacker

A Terraform module to send cloudwatch alarms to slack.

Cloudwatch Slack Notifications

This module deploys resources needed to send cloudwatch alarm information to slack and other destinations. By default, it picks up events for all Alarms in an "Alarm" state and send those events to the targets.

Basic Setup

• Create the AWS resources using the module as shown below.

module "cloudwatch-slack-notifications" {
  source   = "[email protected]:bmukum/cloudwatch-slacker.git?ref=v1"
  name                         = "test-cloudwatch-alarm-slack-notification"
}

• In the management console, navigate to the secrets manager service.
• Find the secret created by the module (${var.name}/cloudwatch_slack_notifications/webhook_url), and replace the value with the slack webhook.
