Traefik Plugin: Auth Delay

A traefik plugin to build additional request headers based on go templates.

This is meant to help replace some of the behavior that is common with request modification middlewares in proxies like Apache/httpd or nginx.

Data passed along to the template from the request object (req) for an example URL (https://localhost:80/some/path?query=true):

key	value	Example
Path	req.URL.EscapedPath()	/some/path
Scheme	req.URL.Scheme	https
Host	req.URL.Host	localhost:80
Method	req.Method	GET
Proto	req.Proto	HTTP/1.1
Query	req.URL.RawQuery	query=true
RequestURI	req.URL.RequestURI()	/some/path?query=true
HttpXForwardedProto	req.Header.Get("X-Forwarded-Proto")	https
HttpXForwardedHost	req.Header.Get("X-Forwarded-Host")	localhost:80
HttpHost	req.Header.Get("Host")	localhost:80

What is a Traefik Plugin

TL;DR; A Traefik plugin is a custom middleware for Traefik.

More on Traefik plugins is written here.

I also wrote an init container that simplifies using "local" plugins (i.e. plugins without Traefik Pilot) inside of Kubernetes.

TODO

• Decide about semantics for modifying, overwriting, appending, or removing headers

Thanks

Inspired by and much boilerplate from traefik-plugin-rewrite-headers, which is a fantastically useful Traefik Plugin.
