dagster

Hey all! I'm following this example for launching ecs  <https://github.com/dagster-io/dagster/tree/0.15.6/examples/deploy_ecs>  and keep running into this error in cloudwatch:
```dagster._check.CheckError: Failure condition: Couldn't import module dagster_aws.ecs when attempting to load the configurable class dagster_aws.ecs.EcsRunLauncher```
Any idea what might raise this error?

Solved: I was missing dagster-aws in a Dockerfile :disappointed:
