Traefik Plugin Rawdata

Traefik Provider plugin to import /api/rawdata from another Traefik instance.

Highly experimental, you might use this as a stopgap solution while migrating services for example. But in production I would avoiding using this plugin as a permanent solution.

Usecase

Traefik's built-in provider configuration has some limits.

For example, https://github.com/traefik/traefik/issues/6063 while Docker Swarm and Docker as-is are supported. You can't specify them both. Nor can you use multiple HTTP endpoints https://doc.traefik.io/traefik/providers/http/#endpoint.

This plugin offers a poor man workaround, where you add another Traefik instance purely for discovery and import this to your main Traefik instance.

Gotchas

This plugin does not attempt to rewrite service IP's, networking information, or anything like hat. So whatever your secondary Traefik instance discovers, needs to be accessible by your primary Traefik instance in the same way.
