# 定义 ReadOnlyMany 存储的方法
|
||
|
|
|
||
|
|
## 概述
|
||
|
|
|
||
|
|
要实现 `ReadOnlyMany` (多机只读) 的前提条件是后端存储是共享存储，在腾讯云上有 `COS` (对象存储) 和 `CFS` (文件存储) 两种。本文介绍这两种共享存储在腾讯云容器服务环境里定义成 PV 的使用方法。
|
||
|
|
|
||
|
|
## COS
|
||
|
|
|
||
|
|
1. `accessModes` 指定 `ReadOnlyMany`。
|
||
|
|
2. `csi.volumeAttributes.additional_args` 指定 `-oro`。
|
||
|
|
|
||
|
|
yaml 示例:
|
||
|
|
|
||
|
|
```yaml
|
||
|
|
apiVersion: v1
|
||
|
|
kind: PersistentVolume
|
||
|
|
metadata:
|
||
|
|
name: registry
|
||
|
|
spec:
|
||
|
|
accessModes:
|
||
|
|
- ReadOnlyMany
|
||
|
|
capacity:
|
||
|
|
storage: 1Gi
|
||
|
|
csi:
|
||
|
|
readOnly: true
|
||
|
|
driver: com.tencent.cloud.csi.cosfs
|
||
|
|
volumeHandle: registry
|
||
|
|
volumeAttributes:
|
||
|
|
additional_args: "-oro"
|
||
|
|
url: "http://cos.ap-chengdu.myqcloud.com"
|
||
|
|
bucket: "roc-**********"
|
||
|
|
path: /test
|
||
|
|
nodePublishSecretRef:
|
||
|
|
name: cos-secret
|
||
|
|
namespace: kube-system
|
||
|
|
```
|
||
|
|
|
||
|
|
## CFS
|
||
|
|
|
||
|
|
1. `accessModes` 指定 `ReadOnlyMany`。
|
||
|
|
2. `mountOptions` 指定 `ro`。
|
||
|
|
|
||
|
|
yaml 示例:
|
||
|
|
|
||
|
|
```yaml
|
||
|
|
apiVersion: v1
|
||
|
|
kind: PersistentVolume
|
||
|

|
||
|
|
name: test
|
||
|
|
spec:
|
||
|
|
accessModes:
|
||
|
|
- ReadOnlyMany
|
||
|
|
capacity:
|
||
|
|
storage: 10Gi
|
||
|
|
storageClassName: cfs
|
||
|
|
persistentVolumeReclaimPolicy: Retain
|
||
|
|
volumeMode: Filesystem
|
||
|
|
mountOptions:
|
||
|
|
- ro
|
||
|
|
csi:
|
||
|
|
driver: com.tencent.cloud.csi.cfs
|
||
|
|
volumeAttributes:
|
||
|
|
host: 10.10.99.99
|
||
|
|
path: /test
|
||
|
|
volumeHandle: cfs-********
|
||
|
|
```
