Can docker-compose / dockerfile access host env vars at build time?

Is it possible for a dockerfile / docker compose file to access the host env vars at build time when running docker-compose build app or do you have to manually pass them into the build command?

Environment variables from the host that you want to use at build time would need to be passed into the build command with the --build-arg flag described here.
