terraform-aws-ecs-cloudwatch-sns-alarms

Terraform module for creating alarms for tracking important changes and occurrences from ECS Services.

This project is part of our comprehensive "SweetOps" approach towards DevOps.

It's 100% Open Source and licensed under the APACHE2.

We literally have hundreds of terraform modules that are Open Source and well-maintained. Check them out!

Usage

IMPORTANT: We do not pin modules to versions in our examples because of the difficulty of keeping the versions in the documentation in sync with the latest released versions. We highly recommend that in your code you pin the version to the exact version you are using so that your infrastructure remains stable, and update versions in a systematic way so that they do not catch you by surprise.

Also, because of a bug in the Terraform registry (hashicorp/terraform#21417), the registry shows many of our inputs as required when in fact they are optional. The table below correctly indicates which inputs are required.

For a complete example, see examples/complete.

For automated tests of the complete example using bats and Terratest, see test.

module "ecs_service_alarms" {
  source = "cloudposse/ecs-cloudwatch-sns-alarms/aws"
  # Cloud Posse recommends pinning every module to a specific version
  # version     = "x.x.x"
  namespace      = "eg"
  stage          = "staging"
  name           = "app"
  cluster_name   = "example"
  service_name   = "app"
}
