Traefik has node affinity

I installed traefik via Helm from this repo: https://helm.traefik.io/traefik

It works, but it creates a persistent volume as hostPath which leads to a node affinity for the traefik pod. So it is not high available and it cannot be moved to another node (e. g. for updating this node).

How can I change this? For example using a NFS volume for traefik.

Here is the relevant part of the volume configuration:

spec:
  capacity:
    storage: 128Mi
  hostPath:
    path: >-
      /var/snap/microk8s/common/default-storage/traefik-traefik-pvc-3dd21e7b-260a-4053-a7f4-9fe6614e685b

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
