docker-compose 未知主机？

Question

I can not use the AWS SDK putObject to upload a file to a fake s3 in local stack. I get an unknown host exception when I try to call putObject. The SDK is calling out to my-bucket.localstack:4572 but my docker contain does not seem to be able to resolve the request and throws a unknown host exception. Is there away to point my-bucket.localstack:4572 to localstack?

version: "3"
services:
  app:
    image: app:latest
    command: run
    networks:
      - mynetwork
    ports:

      - AWS_SECRET_ACCESS_KEY=111
      - AWS_REGION=us-east-1

  localstack:
    image: localstack/localstack
    networks:
      - mynetwork
    ports:
      - "4567-4584:4567-4584"

Configuring the AWS SDK to use path style access resolved my problem.
