# EventBridge Scheduler to Step Functions

This pattern uses EventBridge Scheduler to start the execution of a Step Functions State Machine every minute.

Learn more about this pattern at Serverless Land Patterns: https://serverlessland.com/patterns/eventbridge-schedule-to-step-function-terraform

Important: this application uses various AWS services and there are costs associated with these services after the Free Tier usage - please see the [AWS Pricing page](https://aws.amazon.com/pricing/) for details. You are responsible for any AWS costs incurred. No warranty is implied in this example.

## Requirements

* [Create an AWS account](https://portal.aws.amazon.com/gp/aws/developer/registration/index.html) if you do not already have one and log in. The IAM user that you use must have sufficient permissions to make necessary AWS service calls and manage AWS resources.
* [AWS CLI](https://docs.aws.amazon.com/cli/latest/userguide/install-cliv2.html) installed and configured
* [Git Installed](https://git-scm.com/book/en/v2/Getting-Started-Installing-Git)
* [Terraform](https://learn.hashicorp.com/tutorials/terraform/install-cli?in=terraform/aws-get-started) installed
## Deployment Instructions

1. Create a new directory, navigate to that directory in a terminal and clone the GitHub repository:
    ``` 
    git clone https://github.com/aws-samples/serverless-patterns
    ```
1. Change directory to the pattern directory:
    ```
    cd eventbridge-schedule-to-step-function-terraform
    ```
1. From the command line, initialize terraform to  to downloads and installs the providers defined in the configuration:
    ```
    terraform init
    ```
1. From the command line, apply the configuration in the main.tf file:
    ```
    terraform apply
    ```
1. During the prompts:
    * Enter yes
1. Note the outputs from the deployment process. These contain the resource names and/or ARNs which are used for testing.

## How it works

This Terraform template creates a Step Functions State Machine with a simple "Pass" state that gets executed every minute.

## Testing

After running `terraform apply`, go to the Step Functions console. Find your Step Functions State Machine "my-state-machine", and under the "Executions" section you should find the successful executions.

## Cleanup
 
1. Change directory to the pattern directory:
    ```
    cd eventbridge-schedule-to-step-function-terraform
    ```
2. Delete all created resources by terraform
    ```bash
    terraform destroy
    ```
3. During the prompts:
    * Enter yes
4. Confirm all created resources has been deleted
    ```bash
    terraform show
    ```
