Localstack starts on Docker, but I can’t access

I run a "Docker Compose" to start a localstack instance with the S3 service. It raises normally, but when trying to use AWS CLI to access it I get the following error:

>  aws --endpoint-url=http://localhost:4572 s3api put-bucket-acl --bucket demo-bucket --acl public-read

Connection was closed before we received a valid response from endpoint URL: "http://localhost:4572/demo-bucket?acl".

My Docker-Compose is:

version: '3.7'
services:
  localstack:
    image: localstack/localstack
    container_name: localstack_service
    ports:
      - "4567-4584:4567-4584"
      - "8055:8080"
    environment:
      - SERVICES=s3
      - DEBUG=1
      - DATA_DIR=/tmp/localstack/data
    volumes:
      - ./tmp/localstack:/tmp/localstack   
      - /var/run/docker.sock:/var/run/docker.sock
networks:
  default:
    name: mock_demo

localstack log on Docker:

docker aws docker-compose s3 localstack

First, I see you are using the following version of Localstack:

localstack_demo | LocalStack version: 0.12.1

This way, you are accessing the wrong port for your services, as described in Github, all services must be accessed via Edge Port (the default port being 4566):

Note: Starting with version 0.11.0, all Apis are Exposed via a single edge service, which is accessible on http://localhost:4566 by default (customizable via EDGE_PORT, see further Below).

That said, your command would be as follows:

aws --endpoint-url=http://localhost:4566 s3api put-bucket-acl --bucket demo-bucket --acl public-read
