Seccomp profile in docker-compose file

Docker Engine Compose
1

I’d like to make a docker-compose.yml with a stanza like this:

services:
  desktop:
    # build: .
    image: debian-desktop
    ports:
      - 5902:5901
    networks:
      - shared
    volumes:
      - /home/alx/src:/home/alx/src
    security_opt:
      - seccomp:chrome.json

where chrome.json is a complex seccomp profile. With docker run, this profile can be passed with --security-opt seccomp:./chrome.json, but I can’t figure out how the cognate syntax for docker-compose.yml. I’m not the first person to run into this, and haven’t found any solutions online, so it’s possible there just isn’t one.
