Upstream When

Configuration

For each plugin, the Traefik static configuration must define the module name (as is usual for Go packages).

The following declaration (given here in YAML) defines an plugin:

Copy
# Static configuration

experimental:
  plugins:
    upstreamFirst:
      moduleName: github.com/PandaWorker/traefik-upstream-when
      version: v0.1.1

Here is an example of a file provider dynamic configuration (given here in YAML), where the interesting part is the http.middlewares section:

Copy
# Dynamic configuration

http:
  routers:
    my-router:
      rule: host(`demo.localhost`)
      service: service-foo
      entryPoints:
        - web
      middlewares:
        - my-plugin

  services:
   service-foo:
      loadBalancer:
        servers:
          - url: http://127.0.0.1:5000
  
  middlewares:
    my-plugin:
      upstreamFirst:
        UpstreamUrl: http://127.0.0.1:5001
        UpstreamStatus:
          - 200

Dev Mode

The Traefik static configuration must define a plugin name, a GoPath, and the module name (as is usual for Go packages).

Copy
# Static configuration

experimental:
  devPlugin:
    goPath: /plugins/go
    moduleName: github.com/PandaWorker/traefik-upstream-when
