Hi! I've installed the k3s on ubuntu 24 with curl -sfL https://get.k3s.io | sh -s - --disable local-storage, and today I upgraded with same command. But the traefik not upgraded with he cluster (of course). Can I safely change the helm chart version in the /var/lib/rancher/k3s/server/manifests/traefik.yaml file? What is the recommended upgrade process of traefik?

No. What do you mean by "not upgraded". What were you expecting to see?

Yeah, i realized that the traefik.yaml is automatically managed by k3s, so I cannot change the helm version. I wanted to upgrade trafeik helm chart to version v28.

no, you can’t change the chart version that way. only the app (image) version.
