I'm trying to store acme file in a persistent volume on kubernetes. I'm following this tutorial : https://blog.nobugware.com/post/2019/advanced-traefik-2-0-with-kubernetes/

I have a persistent volume claim (pvc) named traefik-acme-storage.

acme-storage.yaml

---
apiVersion: v1
kind: PersistentVolumeClaim
metadata:
  labels:
    app: traefik
  name: traefik-acme-storage
  namespace: traefik
spec:
  accessModes:
    - ReadWriteOnce
  resources:
    requests:
      storage: "100Mi"

I have also a daemonset which expose traefik and mount a volume named storage-volume linked with my persistent volume claim.

traefik.yaml

---
apiVersion: apps/v1
kind: DaemonSet
metadata:
  namespace: traefik
  name: traefik-ingress-controller
  labels:
    k8s-app: traefik-ingress
    app: traefik

spec:
  selector:
    matchLabels:
      k8s-app: traefik-ingress-lb
      name: traefik-ingress-lb
  template:
    metadata:
      labels:
        k8s-app: traefik-ingress-lb
        name: traefik-ingress-lb
    spec:
      terminationGracePeriodSeconds: 60
      dnsPolicy: ClusterFirstWithHostNet
      hostNetwork: true
      serviceAccountName: traefik-ingress-controller
      containers:
      - name: traefik-ingress-lb
        image: traefik:v2.1.4
        args:
          - --log.level=INFO
          - --entrypoints.web.Address=:80
          - --entrypoints.websecure.Address=:443
          - --providers.kubernetescrd
          - --certificatesresolvers.default.acme.storage=/data/acme.json
        ports:
          - name: http
            containerPort: 80
          - name: https
            containerPort: 443
          - name: admin
            containerPort: 8080
        volumeMounts:
          - name: storage-volume
            mountPath: /data
      volumes:
        - name: storage-volume
          persistentVolumeClaim:
            claimName: traefik-acme-storage

When I apply these two files the pod created by the daemonset and the persistent volume claims are both in pending state.

The error I have in the pod :

Events:
  Type     Reason            Age        From               Message
  ----     ------            ----       ----               -------
  Warning  FailedScheduling  <unknown>  default-scheduler  error while running "VolumeBinding" filter plugin for pod "traefik-ingress-controller-9xgns": pod has unbound immediate PersistentVolumeClaims

The error I have in the persistent volume claim :

  Normal  FailedBinding  11s (x4 over 49s)  persistentvolume-controller  no persistent volumes available for this claim and no storage class is set

Can someone explain to me why the pvc can't bind my volume declared in the daemonset container and how to solve this ?

Thanks by advance
