Description

Hi there 👋,

I have a compose.yml which includes some OCI artifacts and local files. However, when creating a new service that extends a local service, not all attributes get resolved properly.

Steps To Reproduce

# compose.a.yml
services:
  web:
    image: scratch
    environment:
      A: "A"

# compose.b.yml
include:
  - compose.a.yml
services:
  web:
    environment:
       B: B

  worker:
    image: scratch
    extends:
      service: web
    environment:
      C: C

Notice how the worker is missing A, while web has it.

❯ docker compose -f compose.b.yml config
name: the-box-django
services:
  web:
    environment:
      A: A
      B: B
    image: scratch
    networks:
      default: null
  worker:
    environment:
      B: B
      C: C
    image: scratch
    networks:
      default: null
networks:
  default:
    name: the-box-django_default
