Autostart a global traefik reverse proxy

This repository contains all configs needed to auto-start a global traefik instance as a reverse-proxy in a docker-compose setup.

The use case is described in my blog post: https://hollo.me/devops/routing-to-multiple-docker-compose-development-setups-with-traefik.html

Installation

1. Clone this repository to ~/traefik
2. Create the external docker network "gateway"

   docker network create \
   --driver=bridge \
   --attachable \
   --internal=false \
   gateway

3. Create the needed SSL-Certificates using mkcert:

   mkcert "*.example.com"

   and change the config of certificates in the certificates.toml, so that only your needed certificates are listed.
4. Add 127.0.0.1 subdomain1.example.com subdomain2.example.com ... to your /etc/hosts file, so that the trafiic is routed to the traefik instance.
5. cp ~/traefik/com.user.traefik.autostart.plist ~/Library/LaunchAgents/com.user.traefik.autostart.plist
6. Load the service with launchctl load ~/Library/LaunchAgents/com.user.traefik.autostart.plist
7. Check the log file for errors: tail -F ~/Library/Logs/traefik.autostart.log
8. Visit http://127.0.0.1:8080/dashboard/#/ - You should see your traefik dashboard.

If you're not my future self, adapt the paths to the user's home directory in the configs before running anything. 😬
