What's the docker-compose equivalent of docker run --init?

According to https://github.com/krallin/tini#using-tini, tini is built into docker, and can be used by passing the --init flag to docker run. In my case I'm using docker-compose and don't invoke docker run directly. How can I pass this flag?

Here is an example from Docker Docs:

services:
  web:
    image: alpine:latest
    init: true

If you are using version 2 of docker-compose, the configuration parameter is called init.

Example:

version: '2.2'
services:
  web:
    image: alpine:latest
    init: /usr/libexec/docker-init

Please see here for more details: https://docs.docker.com/compose/compose-file/compose-file-v2/#init

If you're using docker-compose version 3, apparently this has been removed and returned in version 3.7. Please refer to the following ticket: https://github.com/docker/docker.github.io/issues/3149
