I'm looking for a way to scale up a docker-compose service & saw the --scale option but could not find any method to get the index & count within each container.

Here's a simplified compose file:

version: '2.1'
services:
  my_thing:
    restart: always
    build: .
    entrypoint: /entry.sh
    depends_on:
      - database
  database:
    restart: always
    image: postgres:12.1-alpine
    ...

If I did docker-compose up my_thing --scale 5 within the entry I'd like to be able to see which instance I am (1 to 5) …
