Extending service in the same docker-compose.yml file

Let's say I have a service like:

my-service:
  build:
    context: "./my-service"
    dockerfile: Dockerfile.dev
  ports:
    - 8072:8000
  depends_on:
    - another-service
  environment:
    PROXY: "true"

And I want to create my-service-2 with exactly the same configurations but only with different port. I could do this:

my-service-2:
  build:
    context: "./my-service"
    dockerfile: Dockerfile.dev
  ports:
    - 8073:8000
  depends_on:
    - another-service
  environment:
    PROXY: "true"

But is there any way I could do something like:

my-service-2 extends my-service:
  ports:
    - 8073:8000

So I wouldn't need to rewrite the same thing many times.

Thanks!

Extends is supported till compose v2.1 although its usage is not how you asked for.

You need to keep the common configurations in one compose file and in the docker-compose.yml you can define the services extending from the common compose configuration.

Here is an elaborate example and documentation on this: https://docs.docker.com/compose/extends/
