How to provide support for Persistent Volume provisioner within an kubernetes cluster?

Question

Ok so this might be a basic question, but i'm new to kubernetes and tried to install wordpress using helm unto it, using the stable/wordpress chart, but i keep getting an error "pod has unbound immediate PersistentVolumeClaims (repeated 2 times)" is this because of the requirement in here https://github.com/helm/charts/tree/master/stable/wordpress . "PV provisioner support in the underlying infrastructure" how do i enable this in my infrastructure, i have setup my cluster across three nodes on digitalocean, i've tried searching for tutorials on this, with no luck until now. Please let me know what i'm missing, thanks.

Answer 1

PersistentVolume types are implemented as plugins. Kubernetes currently supports the following plugins:

GCEPersistentDisk
AWSElasticBlockStore
AzureFile
AzureDisk
FC (Fibre Channel)
Flexvolume
Flocker
NFS
iSCSI
RBD (Ceph Block Device)
CephFS
Cinder (OpenStack block storage)
Glusterfs
VsphereVolume
Quobyte Volumes
HostPath (Single node testing only – local storage is not supported in any way and WILL NOT WORK in a multi-node cluster)
Portworx Volumes
ScaleIO Volumes
StorageOS

You can enable support for PVs or Dynamic PVs using thoese plugins.

detail reference

On Digital Ocean you can use block storage for volumes.

Answer 2

Kubernetes can be set-up for Dynamic Volume Provisioning . This would allow the Chart to run to completion using the default configuration as the PVs would be provisioned on-demand.
