Lost with taint and toleration, please help


I have several nodes into my cluster, all are working fine.
I would like to “specialize” one node, to finally just listening for Traefik :80 and :443

Just ensuring klipper-lb pod created by traefik daemonset should be enough, in my understanding.
Traefik is installed by Helm, but I can handle specific configuration for tests.

How to do this ?
I successfully tested tainting the specialized node, to exclude globally everything, but I didn’t found toleration configuration for Traefik, to work on all existing nodes AND on the very specific one.

Thanks in advance.
