K8S之Volume存储

一、临时存储卷：emptyDir

创建一个空卷到Pod中，Pod删除，该卷也被删除

默认存储路径为：/var/lib/kubelet/pods/<Pod ID>/volumes/kubernetes.io~empty-dir/

spec:
  containers:
  - name: empty
    image: nginx
    imagePullPolicy: IfNotPresent
    ports:
    - containerPort: 80
    volumeMounts:
      - name: data
        mountPath: /data
  volumes:
  - name: data
    emptyDir: {
    
    }

二、节点存储卷hostPath

挂载节点上的目录或者文件到Pod容器中

挂载宿主机的/tmp目录到Pod容器的/data目录

spec:
  containers:
  - name: empty
    image: nginx
    imagePullPolicy: IfNotPresent
    ports:
    - containerPort: 80
    volumeMounts:
      - name: data
        mountPath: /data
  volumes:
  - name: data
    hostPath:
      path: /tmp

三、网络存储卷NFS

spec:
  containers:
  - name: empty
    image: nginx
    imagePullPolicy: IfNotPresent
    ports:
    - containerPort: 80
    volumeMounts:
      - name: data
        mountPath: /data
  volumes:
  - name: data
    nfs:
      server: 192.168.1.10			#NFS服务器地址
      path: /app					#NFS共享的目录
