我有以下PersistentVolumeClaim:
apiVersion: v1
kind: PersistentVolumeClaim
metadata:
name: nginx-pvc
spec:
accessModes:
- ReadWriteOnce
resources:
requests:
storage: 256Mi
storageClassName: fask
和部署:
apiVersion: apps/v1
kind: Deployment
metadata:
name: nginx-deployment
spec:
replicas: 2
selector:
matchLabels:
app: nginx
template:
metadata:
labels:
app: nginx
spec:
containers:
- name: nginx
image: nginx:1.7.9
ports:
- containerPort: 80
volumeMounts:
- name: data
mountPath: "/var/www/html"
volumes:
- name: data
persistentVolumeClaim:
claimName: nginx-pvc
如果我使用单个副本部署运行,我的 PV 将由 vSphere StorageClass动态创建
但是,如果我有超过2 个副本,它将无法创建第二个 PV:
AttachVolume.Attach failed for volume "pvc-8facf319-6b1a-11e8-935b-00505680b1b8" : Failed to add disk 'scsi0:1'.
