deploying Portainer on Kubernetes Cluster failed

after deploying Portainer on Kubernetes Cluster (1 master, 2 workers), following https://documentation.portainer.io/v2.0/deploy/ceinstallk8s/, by

helm install --create-namespace -n portainer portainer portainer/portainer --set persistence.storageClass=slow

I got the status:

kubectl get all -n portainer
NAME                             READY   STATUS    RESTARTS   AGE
pod/portainer-6cb48f955f-qmtdq   0/1     Pending   0          2d

NAME                TYPE       CLUSTER-IP      EXTERNAL-IP   PORT(S)                          AGE
service/portainer   NodePort   10.97.158.200   <none>       9000:30777/TCP,30776:30776/TCP   2d3h

NAME                        READY   UP-TO-DATE   AVAILABLE   AGE
deployment.apps/portainer   0/1     1            0           2d

NAME                                   DESIRED   CURRENT   READY   AGE
replicaset.apps/portainer-6cb48f955f   1         1         0       2d

So, The pod is not READY, with STATUS Pending. The service is up but has no EXTERNAL-IP. The deployment is not READY or AVAILABLE. The ReplicaSet is not READY.

And I can't access the instance on port 30777. i.e. http://20.199.64.113:30777/

More 'kubectl describe' info:

root@kubemaster:/home/kubemaster# kubectl describe pod portainer -n portainer

root@kubemaster:/home/kubemaster# kubectl describe pv portainer -n portainer
Error from server (NotFound): persistentvolumes "portainer" not found

I did researched the below error/warning:


Warning  FailedScheduling  129m  default-scheduler  0/3 nodes are available: 3 pod has unbound immediate PersistentVolumeClaims.


Warning  ProvisioningFailed  2m22s (x259 over 9h)  persistentvolume-controller  Failed to provision volume with StorageClass "slow": AzureDisk -  failed to get Azure Cloud Provider. GetCloudProvider returned <nil> instead

But still wasn't able to enable Portainer instance.

Is there anything i missed out or anyway to debug

thanks ahead

If you are using PersistentVolumeClaim you need a volume provisioner for Dynamic Volume Provisioning. The bigger cloud providers typically has this.

If you don't have a volume provisioner in your cluster, you have to create a PersistentVolume resource and possibly also a StorageClass and declare how to use your storage system.

Take a look: portainer-on-kubernetes.
So in your case as you have mentioned you can install external volume provisioner - NFS subdir external provisioner.
