TIL you can include other files via Docker Compose

Docker Compose has an include directive that lets you split your setup into multiple files:

# compose.yml
include:
  - path: ./compose/temporal/compose.yml
    env_file:
      - ./compose/temporal/.env
  - path: ./compose/compose-db.yml

services:
  app:
    depends_on:
      - db
      - temporal

Each included file is resolved relative to its own directory, so paths within it just work. The included services can then be referenced directly via depends_on or networking. It also works recursively.
