traefik-http-shaping

HTTP Shaping is a middleware plugin for traefik allowing to track IN/OUT traffic of an HTTP endpoint and limit network usage. Once any of the limit is reached, the HTTP request returns a too many requests status code.

Adding the middleware

In traefik.yml, using the dev method, add:

experimental:
  localPlugins:
    httpShaping:
      moduleName: github.com/martinlevesque/http_shaping

and copy the plugin into your local folder:

mkdir -p plugins-local/src/github.com/martinlevesque/http_shaping
git clone https://github.com/martinlevesque/http_shaping.git plugins-local/src/github.com/martinlevesque/http_shaping
