kubernetes 存储-基于NFS的PV创建应用

kubernetes 存储-基于NFS的PV创建应用

1. 安装nfs

yum install -y nfs-utils rpcbind

2. 创建共享目录

mkdir /data

3. 更改目录属主

chown -R nfsnobody:nfsnobody /data

4. 修改配置文件

vim /etc/exports
/nfs/data/  10.10.10.0/24(rw,sync,all_squash)  ## 可读写，同步到本地，压缩为nfsnobody权限

5. 启动nfs

systemctl start nfs
systemctl enable nfs

6. 创建 pv 资源

vim nginx-html-pv.yaml

apiVersion: v1
kind: PersistentVolume
metadata:
  name: nginx-html-pv
spec:
  capacity:
    storage: 1Gi     ## 申请储存空间
  accessModes:
    - ReadWriteMany     ## 允许多个pod读写
  nfs:
    path: /nfs/data/nginx/html   ## 需要申请的nfs目录
    server: 10.10.10.10    ## nfs服务器地址

7. 创建 pvc 资源

vim nginx-html-pvc.yaml

apiVersion: v1
kind: PersistentVolumeClaim
metadata:
  name: nginx-html-pvc
  labels:
    app: nginx
spec:
  accessModes:
    - ReadWriteMany
  resources:
    requests:
      storage: 1Gi    ## 需要的大小，匹配pv

8. 创建 Deploymnet 资源

vim nginx-deployment.yaml

apiVersion: apps/v1
kind: Deployment
metadata:
  name: nginx-deployment
  labels:
    app: nginx
spec:
  replicas: 2      ## pod 附本数
  selector:
    matchLabels:
      app: nginx
  strategy:
    type: Recreate   ## 升级方式
  template:
    metadata:
      labels:
        app: nginx
    spec:
      imagePullSecrets:
      - name: registry-secret   # 下载私有仓库的镜像时需要设置Secret
      containers:
      - image: hub.ko.com/k8s-harbor/nginx:v1
        name: nginx
        ports:
        - containerPort: 80
        volumeMounts:
        - name: nginx-html-storage       # 使用 pvc 并挂载
          mountPath: /usr/share/nginx/html
      volumes:
      - name: nginx-html-storage         ## 申明 pvc
        persistentVolumeClaim:
          claimName: nginx-html-pvc
