Serverless Cloudwatch alerts 2 Slack

Cloudwatch alerts on slack.

Usually glueing Cloudwatch alerts to Slack requires a Lambda function, requires you to know how to parse the SNS, and specify a channel.

This projects creates a lambda function that knows how to send cloudwatch-alert-SNSs to Slack. You can use this project to handle alerts for multiple projects.

Usage

• do serverless install -u https://github.com/dav009/serverless-aws-alarms-notifier
• Go to AWS ec2's parameter store and add a new parameter containing your slack token
• Edit serverless.yml replacing parameter_name_where_slack_token_is_store for the parameter name on ec2 parameter store
• Deploy
  • run sh bootstrap.sh (just neded the first time..)
  • run sls deploy
• Use the SNS generated by this project when creating your Cloudwatch alerts (cloudwatch-alerts-sns).
  • When creating your Cloudwatch alarm add channel:XX to the alarm description, replace XX with a slack channel

Note: make sure the role of the generated lambda function has access to sms:xx and to the KMS key you used to encrypt your parameter.
