Creating a PersistentVolume on Okteto Cloud - postgresql

Question

When I try to create a persistentVolume on Okteto Cloud with the following definition:
kind: PersistentVolume
apiVersion: v1
metadata:
name: postgres-pv
labels:
type: local
app: postgres
spec:
storageClassName: manual
capacity:
storage: 5Gi
accessModes:
- ReadWriteMany
hostPath:
path: "/mnt/data"
I get the following error:
Error from server (Forbidden): error when retrieving current configuration of:
Resource: "/v1, Resource=persistentvolumes", GroupVersionKind: "/v1, Kind=PersistentVolume"
Name: "postgres-pv", Namespace: ""
Object: &{map["apiVersion":"v1" "kind":"PersistentVolume" "metadata":map["annotations":map["kubectl.kubernetes.io/last-applied-configuration":""] "labels":map["app":"postgres" "type":"local"] "name":"postgres-pv"] "spec":map["accessModes":["ReadWriteMany"] "capacity":map["storage":"5Gi"] "hostPath":map["path":"/mnt/data"]]]}
from server for: "deploy/k8s.postgres.yml": persistentvolumes "postgres-pv" is forbidden: User "system:serviceaccount:okteto:07e6fdbf-55c2-4642-81e3-051e8309000f" cannot get resource "persistentvolumes" in API group "" at the cluster scope
However according to the Okteto cloud docs, persistentVolumes seem to be authorized.
How would I create one on there ?
.
For context I'm trying to reproduce a simple postgres deployment (no replication, no backups).
Here's my complete deployment file:
apiVersion: extensions/v1beta1
kind: Deployment
metadata:
name: postgres
spec:
replicas: 1
template:

app: postgres

volumeMounts:

Persistent volumes is a cluster-wide resource and it is not allowed.
The docs are wrong, thanks for pointing it out.
You can create instead PersistentVolumeClaims using the default storage class (and remove the persistent volume manifest):
apiVersion: v1
kind: PersistentVolumeClaim
metadata:
name: postgres-pv-claim
spec:
accessModes:
- ReadWriteOnce
resources:
requests:
storage: 10Gi
Hope it helps :-)
