como vincular uma reivindicação de volume persistente a um gcePersistentDisk?
Gostaria de vincular PersistentVolumeClaim com um gcePersistentDisk PersistentVolume. Abaixo os passos que eu fiz para conseguir isso:
1. Criação do gcePersistentDisk:gcloud compute disks create --size=2GB --zone=us-east1-b gce-nfs-disk
# pv-pvc.yml
apiVersion: v1
kind: PersistentVolume
metadata:
name: nfs-pv
spec:
capacity:
storage: 2Gi
accessModes:
- ReadWriteOnce
gcePersistentDisk:
pdName: gce-nfs-disk
fsType: ext4
---
apiVersion: v1
kind: PersistentVolumeClaim
metadata:
name: nfs-pvc
labels:
app: test
spec:
accessModes:
- ReadWriteOnce
resources:
requests:
storage: 2Gi
Depois de correrkubectl apply -f pv-pvc.yml, anfs-pvc não está ligado anfs-pv. De fato, abaixo está a lista dos PersistentVolume e PersistentVolumeClaim que tenho:
$ kubectl get pv
NAME CAPACITY ACCESS MODES RECLAIM POLICY STATUS CLAIM STORAGECLASS REASON AGE
nfs-pv 2Gi RWO Retain Available 30s
pvc-16e4cdf2-cd3d-11e7-83ae-42010a8e0243 2Gi RWO Delete Bound default/nfs-pvc standard 26s
$ kubectl get pvc
NAME STATUS VOLUME CAPACITY ACCESS MODES STORAGECLASS AGE
nfs-pvc Bound pvc-16e4cdf2-cd3d-11e7-83ae-42010a8e0243 2Gi RWO standard 59s
O PersistentVolume obtido é um volume no disco do nó que criei no Google Container Engine. Então, eu perdi alguma coisa?
PS: a versão do kubernetes
$ kubectl version
