k8s 使用nfs创建pv和pvc,将pvc挂到nginx应用中的完整配置文件

以下是使用NFS创建PV和PVC，并将PVC挂到Nginx应用中的完整配置文件：

1. 创建NFS服务器和共享目录

在NFS服务器上创建一个共享目录，并将其导出为NFS共享。

2. 创建PV和PVC

创建PV和PVC的yaml文件，示例：

apiVersion: v1
kind: PersistentVolume
metadata:
  name: nfs-pv
spec:
  capacity:
    storage: 10Gi
  accessModes:
    - ReadWriteMany
  nfs:
    server: nfs-server-ip
    path: /path/to/nfs/share
---
kind: PersistentVolumeClaim
apiVersion: v1
metadata:
  name: nfs-pvc
spec:
  accessModes:
    - ReadWriteMany
  resources:
    requests:
      storage: 10Gi

3. 创建Nginx Deployment和Service

创建Nginx Deployment和Service的yaml文件，示例：

kind: Deployment
apiVersion: apps/v1
metadata:
  name: nginx-deployment
spec:
  replicas: 1
  selector:
    matchLabels:
      app: nginx
  template:
    metadata:
      labels:
        app: nginx
    spec:
      containers:
        - name: nginx
          image: nginx:latest
          ports:
            - containerPort: 80
          volumeMounts:
            - name: nfs-volume
              mountPath: "/usr/share/nginx/html"
      volumes:
        - name: nfs-volume
          persistentVolumeClaim:
            claimName: nfs-pvc
---
apiVersion: v1
kind: Service
metadata:
  name: nginx-service
spec:
  selector:
    app: nginx
  ports:
    - name: http
      port: 80
      targetPort: 80
  type: LoadBalancer

4. 应用配置文件

应用配置文件的yaml文件，示例：

apiVersion: v1
kind: ConfigMap
metadata:
  name: nginx-config
data:
  nginx.conf: |
    worker_processes 1;
    events { worker_connections 1024; }
    http {
        server {
            listen 80;
            server_name localhost;
            location / {
                root /usr/share/nginx/html;
                index index.html;
            }
        }
    }
---
apiVersion: apps/v1
kind: Deployment
metadata:
  name: nginx-deployment
spec:
  replicas: 1
  selector:
    matchLabels:
      app: nginx
  template:
    metadata:
      labels:
        app: nginx
    spec:
      containers:
        - name: nginx
          image: nginx:latest
          ports:
            - containerPort: 80
          volumeMounts:
            - name: nfs-volume
              mountPath: "/usr/share/nginx/html"
            - name: nginx-config
              mountPath: "/etc/nginx/nginx.conf"
              subPath: nginx.conf
      volumes:
        - name: nfs-volume
          persistentVolumeClaim:
            claimName: nfs-pvc
        - name: nginx-config
          configMap:
            name: nginx-config

其中，应用配置文件中的ConfigMap可自定义Nginx配置。

5. 应用配置文件

将以上配置文件应用到Kubernetes集群中：

kubectl apply -f pv-pvc.yaml
kubectl apply -f nginx.yaml
kubectl apply -f nginx-config.yaml

这样，就完成了使用NFS创建PV和PVC，并将PVC挂到Nginx应用中的完整配置。
