README

falcon

falcon is your friendly neighborhood local development Docker reverse proxy. That mouthful of words basically means that falcon lets you access your Docker containers at friendly domain addresses, like yourwebapp.docker instead of localhost:<whatever_port_was_free>. Behind the scenes, falcon uses Traefik to perform all proxying and some DNS trickery to get everything working properly.

Installation

Because falcon is written in Go, the easiest way to install it is to use Go's module system. After installing Go, simply run go install github.com/Hawkbawk/falcon@latest to install falcon. Assuming you've added your GOPATH to your regular PATH, you should be able to run falcon and you should see a friendly message explaining what commands are available to you. For now, there are only two commands, up, that start falcon and its requisite services, and down, which stops falcon and restores your networking configuration to its default state.

Configuration

Because falcon uses Traefik behind the scense for all proxying, you'll be using labels to tell falcon the domain (and possibly poprt) that you want to be able to access your container at. The template below shows you the labels that you'd need to add in order to access your application at the domain of your choice:

- traefik.enable=true # required to make proxying work
- traefik.http.routers.<app_name_here>.rule=Host(`<desired_domain>.docker`) # required to specify domain
- traefik.http.routers.<app_name_here>.loadbalancer.port=80 # optional

Note that the port option allows you to specify what port your container is running your application on. This option is only necessary if your container exposes multiple ports. If your container only exposes and works on a single port, Traefik will automatically detect what port to use.

For further reading, see Traefik's documentation related to routing with Docker
