# Mad Adder

AWS cloud scheduler with second-level precision based on Terraform, CloudWatch, Lambda, and SNS.

Using CloudWatch to trigger Lambda execution at a given intervals, the Lambda app(s) then trigger SNS notifications at second-level granularity.  The SNS topic can then be used to spawn Lambda functions to do your bidding.

## Deployment

1. Configure the `shadowconf.hcl` file in the project root as needed.

2. Execute `shadow fax *.tf.tpl`.

3. Run `terraform init`, `plan`, and `apply` in the project root to create the

   SNS topic.

4. Add the `topic_arn` to the `shadowconf.hcl` file in the project root.

5. Execute `shadow fax terraform.tpl` to generate the `terraform` directory.

6. Change into the `terraform` directory and execute `terraform init`, `plan`,

   and `apply`.
