Traefik - proxy and load balancer

Traefik has been released in version 2.9.5. As always we provide a patched version which includes our Mesos provider is included. With this version we have also implemented dynamiclable-names. This simplifies adding and updating labels.

How to use dynamic label names?

All Traefik labels need a name. As example: “homepage”:

traefik.http.routers.homepage.entrypoints: "web"

To have this created dynamically, it must be rewritten as follows:

traefik.http.routers.__mesos_taskid__.entrypoints": "web"

The Traefik Mesos provider replaces __mesos_taskid__ in the label-key as well as in the label-value, by the unique taskID.
