Trigger Step Function with API Gateway and use Fargate within Step Function?

Question

I want to be able to have a step function that does the following:

1. The step function starts with a call to API Gateway from my web app
2. The step function starts a Fargate pod based on a specific image
3. The step function runs a task on the pod it just created
3. After the Fargate task completes, terminate the pod so it does not consume resources

Is this possible to tell Step Functions to start a new pod based on a certain image and then terminate that pod after it returns a success code?

I have not been able to find any info on this.

Thank you

Please do respect the time others dedicated helping you by mark answers as accepted.

You can do this by -

1. Once the task has been completed, you can query the TaskARN through the [metadata service](https://docs.aws.amazon.com/AmazonECS/latest/userguide/task-metadata-endpoint-v4-fargate.html) and terminate the task; 
2. You should also mark the step function step as [completed](https://docs.aws.amazon.com/step-functions/latest/dg/connect-ecs.html#connect-ecs-pass-to); 
3. Fargate tasks never "completes" before the "pod".
