Maintain and update your traefik.io basic rules with GIT + CI.
The mapping.json file is a simplified version of the traefik REST syntax.
In your CI, set process.env.TRAEFIK_URL="http://127.0.0.1:8080/api/providers/rest"
Run node deploy to update traefik configuration from mapping.json or let your CI do the job.
