### Is there an existing issue for this?

- [X] I have searched the existing issues

### Current Behavior

I am using below docker-compose file to start the localstack container with es service
```
version: "3"
services:
  wiremock:
    image: "rodolpheche/wiremock"
    ports:
      - "8080"
  localstack:
    image: "localstack/localstack-full:0.14.2"
    ports:
      - "4566"
      - "4510:4510"
    environment:
      AWS_ACCESS_KEY_ID: "local-access-key-id"
      AWS_SECRET_ACCESS_KEY: "local-secret-access-key"
      HOSTNAME_EXTERNAL: "localstack"
      OPENSEARCH_ENDPOINT_STRATEGY: "port"
      SERVICES: "es"
      EDGE_PORT: "4566"
    volumes:
      - "/var/run/docker.sock:/var/run/docker.sock"

```

running `aws --region ap-south-1 --endpoint-url http://localstack:4566 es create-elasticsearch-domain --domain-name my-domain` to create domain
this command is returning `localhost:4510` as an endpoint, I am able to curl `curl localhost:4510` within localstack bash but 
neither on the host machine nor in `wiremock` container.



### Expected Behavior

I should able to access elastic search domain in host machine as well in another container
