### 挂载NFS存储到K8s容器步骤
| 步骤 | 描述 |
| ------ | ------ |
| 1 | 创建NFS服务器并共享目录 |
| 2 | 创建Kubernetes的ServiceAccount |
| 3 | 创建Secret对象来存储NFS服务器的认证信息 |
| 4 | 创建PersistentVolume对象用于配置NFS存储 |
| 5 | 创建PersistentVolumeClaim对象来声明NFS存储 |
| 6 | 创建Pod对象并挂载NFS存储 |
### 代码示例
#### 步骤1:创建NFS服务器并共享目录
```bash
# 安装NFS服务器
$ sudo apt-get update
$ sudo apt-get install nfs-kernel-server
# 创建并共享目录
$ sudo mkdir /nfs_share
$ sudo chown nobody:nogroup /nfs_share
$ sudo chmod 777 /nfs_share
$ sudo vi /etc/exports
# /nfs_share *(rw,sync,no_subtree_check)
$ sudo exportfs -a
```
#### 步骤2:创建Kubernetes的ServiceAccount
```yaml
apiVersion: v1
kind: ServiceAccount
metadata:
name: nfs-client
```
#### 步骤3:创建Secret对象来存储NFS服务器的认证信息
```yaml
apiVersion: v1
kind: Secret
metadata:
name: nfs-secret
type: Opaque
data:
username:
password:
```
#### 步骤4:创建PersistentVolume对象用于配置NFS存储
```yaml
apiVersion: v1
kind: PersistentVolume
metadata:
name: nfs-pv
spec:
capacity:
storage: 1Gi
accessModes:
- ReadWriteMany
nfs:
server:
path: /nfs_share
```
#### 步骤5:创建PersistentVolumeClaim对象来声明NFS存储
```yaml
apiVersion: v1
kind: PersistentVolumeClaim
metadata:
name: nfs-pvc
spec:
accessModes:
- ReadWriteMany
resources:
requests:
storage: 1Gi
```
#### 步骤6:创建Pod对象并挂载NFS存储
```yaml
apiVersion: v1
kind: Pod
metadata:
name: nfs-pod
spec:
containers:
- name: nfs-container
image: nginx
volumeMounts:
- mountPath: "/mnt/nfs"
name: nfs-volume
volumes:
- name: nfs-volume
persistentVolumeClaim:
claimName: nfs-pvc
```
### 总结
通过以上步骤,您已经成功地将NFS存储挂载到Kubernetes容器中。这样可以使容器之间可以共享存储空间,方便数据共享和持久化存储。希望这篇文章对您有所帮助,祝您在Kubernetes的学习和实践中顺利前行!
