Show HN: SSM/KMS/ENV-aware Go template file fetcher and parser for AWS ECS

Since ECS is missing k8s configMap/secrets style integrations for SSM and KMS I wrote this small tool to help get secrets into place without a bunch of ECS-specific custom entrypoint code. Scratches a particular itch I've encountered a number of times working with ECS and thought it might be useful to anyone else running AWS ECS services.
