Now I only have terminal to access kubernetes cluster now, check the ingress controller like this:

$ k get daemonset --all-namespaces
NAMESPACE     NAME                         DESIRED   CURRENT   READY   UP-TO-DATE   AVAILABLE   NODE SELECTOR                              AGE
kube-system   traefik-ingress-controller   0         0         0       0            0           IngressProxy=true                          60d
logging       fluentd-es                   0         0         0       0            0           beta.kubernetes.io/fluentd-ds-ready=true   28d

I am now using kubectl(v1.15.2) to scale daemon set like this:

kubectl scale --replicas=1 DaemonSet/traefik-ingress-controller -n kube-system

but it shows:

Error from server (NotFound): the server could not find the requested resource

what should I do to start the traefik in terminal using command line? This is my daemon set describe output:
