Header rewrite Traefik plugin

Traefik plugin that can modify http headers.

Configuration

Traefik static configuration for local plugin:

...
experimental:
  localPlugins:
    header-rewrite:
      moduleName: github.com/gritgmbh/header-rewrite-traefik-plugin

Plugin is then configured as a route middleware

http:
  routers:
    route1:
      middlewares: ["headerRewrite"]
  middlewares:
    headerRewrite:
      plugin:
        header-rewrite:
          from: X-Forwarded-Access-Token
          to: Authorization
          prefix: 'Bearer '
          keepOriginal: false
          keepOriginalTarget: true
          regex: "^(.+)-old$"
          replacement: "$1"
 

In this example, when there is X-Forwarded-Access-Token header, it's values will be moved into Authorization header with Bearer as a value prefix. The X-Forwarded-Access-Token header will be removed (keepOriginal: false) and if there were any values in Authorization header, they will stay there (keepOriginalTarget: true). If a Regex is given, this is evaluated and all matches are replaced with Replacement.
