# Below is the configuration for using an existing docker network instead of the letting docker-compose create one by default. I use an external network to handle routing and deployment of multiple docker compose stacks on same server using traefik (https://github.com/traefik/traefik).
# While running this docke-compose, you have 2 options
#   1. Comment out the below 4 lines, and run this stack as usual, with `docker-compose up`
#   2. Create a docker network with name `traefik` using command `docker network create traefik`, and move onto better things in your life.
