Install plugins as part of docker compose script
Sorry if this is a dumb question, but this is the first container I'm creating with docker-compose.

The homepage docs explain (quite well I might add :-)) what to do if:
- You want to use docker compose
- Use plugins installed via npm or startup.sh
- Needing extra packages such as ffmpeg via environment variable.

What's not clear is if you can specify the plugins via an environment variable as part of the docker-compose.yml file. Is this possible?

I'm simply trying to install https://www.npmjs.com/package/homebridge-homeassistant so my container will work out of the box with all container-required config in one location :-)
