<p>Im struggling to get Traefik working on K8s with ACME enabled. I want to store the certs as suggested on a persistantVolume. This for the fact that requesting certs is rateLimited and in case of pod restarts the cert would get lost. Below is my full config that is used for stable/traefik (helm chart) and installed in Azure AKS.</p>

<p>There are a issue that do not seem to work (or im just doing it wrong ofcourse). </p>

<p><strong>pod has unbound immediate PersistentVolumeClaims</strong></p>

<p>This is the initial error that i receive when booting up the pods. The weird thing is that the PersistantVolumeClaim is actually there and ready. When i change the volume itself in my Azure portal it also says its mount to my server</p>

<pre><code>traefik-acme

<p>Also the storageClass itself is active:</p>

<pre><code>$ kubectl get sc --all-namespaces

managed-premium     kubernetes.io/azure-disk   4d
</code></pre>

<p>When i then wait a little longer i receive below error:
<code>Unable to mount volumes for pod "traefik-d65fcbc8b-lkzsh_default(b68c8aa3-602d-11e9-a537-92753888c74b)": timeout expired waiting for volumes to attach or mount for pod "default"/"traefik-d65fcbc8b-lkzsh". list of unmounted volumes=[acme]. list of unattached volumes=[config acme default-token-p2lgf]</code></p>

<p>For your issue, it seems you misunderstand the persist volume claims. When you use the command:</p>

<pre><code>kubectl get sc --all-namespaces
</code></pre>

<p>It just shows the storage class, not the persist volume claims. The storage class is used to define how a unit of storage is dynamically created with a persistent volume. You need to create the persist volume claims as you need like this:</p>

<pre><code>apiVersion: v1
kind: PersistentVolumeClaim
metadata:
  name: azure-managed-disk
spec:
  accessModes:
  - ReadWriteOnce
  storageClassName: managed-premium
  resources:
    requests:
      storage: 5Gi
</code></pre>

<p>And you can use the command to show the persist volume claims like below:</p>

<pre><code>kubectl get pvc --all-namespaces
</code></pre>

<p>And it actually shows the persist volume claims that you create. Take a look at the <a href="https://learn.microsoft.com/en-us/azure/aks/azure-disks-dynamic-pv" rel="nofollow noreferrer">Dynamically create and use a persistent volume with Azure disks in Azure Kubernetes Service (AKS)</a>. Or <a href="https://learn.microsoft.com/en-us/azure/aks/azure-disk-volume" rel="nofollow noreferrer">Use the special disk that you create</a>.</p>

<p><strong>Update</strong></p>

<p>Also, I get the error as you, but when the pod in the running state, I check inside the pod and find the volumes all mounted correctly. So I guess if the error came because the pod is not in the running state. When the pod in the running state, volumes will mount as expected.</p>
