Should I use Docker compose in production?

Docker Compose is very suitable for production, if you're deploying to 1 host. Let's face it, not every application needs to scale to infinity and beyond with multiple forms of redundancy. If you set up restart policies on your containers then they will automatically come up if they crash, or if you reboot your server.
