Caddy as a container Directions here -> https://hub.docker.com/r/abiosoft/caddy/

in Docker compose:

1. Add this to compose

   app:
   image: keymetrics/pm2:8-alpine
   	// whatever your node app is
   caddy: 
   image: abiosoft/caddy
   depends_on: 
     - app
   ports:
     - "80:80"
     - "443:443"
   volumes:
     - ./Caddyfile:/etc/Caddyfile
     - $HOME/.caddy:/root/.caddy

2. Add a Caddyfile in your project, use the container name of your app

   slime.yu-mi.us {
       proxy / app:3000
   }

3. Run docker-compose up -d
4. Your app is (hopefully) live :)
