在Kubernetes中,可以通过在多个Pod之间共享一个EBS卷来实现这个需求。以下是一种实现方法:
apiVersion: v1
kind: PersistentVolumeClaim
metadata:
name: my-pvc
spec:
accessModes:
- ReadWriteOnce
resources:
requests:
storage: 10Gi
apiVersion: v1
kind: PersistentVolumeClaim
metadata:
name: my-pvc
spec:
accessModes:
- ReadOnlyMany
resources:
requests:
storage: 10Gi
apiVersion: v1
kind: Pod
metadata:
name: read-write-pod
spec:
containers:
- name: my-app
image: my-app-image
volumeMounts:
- name: shared-volume
mountPath: /data
volumes:
- name: shared-volume
persistentVolumeClaim:
claimName: my-pvc
apiVersion: v1
kind: Pod
metadata:
name: read-only-pod
spec:
containers:
- name: my-app
image: my-app-image
volumeMounts:
- name: shared-volume
mountPath: /data
readOnly: true
volumes:
- name: shared-volume
persistentVolumeClaim:
claimName: my-pvc
通过这种方式,读写权限的Pod可以向EBS卷写入数据,并与只读权限的Pod共享这个卷。注意,需要确保在只读权限的Pod中设置了readOnly: true
,以防止意外的写入操作。
