sts

在sts之中使用的是volumeClaimTemplates进行相关的存储的配置

apiVersion: apps/v1
kind: StatefulSet
metadata:
  name: web
spec:
  selector:
    matchLabels:
      app: nginx # 必须匹配 .spec.template.metadata.labels
  serviceName: "nginx"
  replicas: 3 # 默认值是 1
  minReadySeconds: 10 # 默认值是 0
  template:
    metadata:
      labels:
        app: nginx # 必须匹配 .spec.selector.matchLabels
    spec:
      terminationGracePeriodSeconds: 10
      containers:
      - name: nginx
        image: registry.k8s.io/nginx-slim:0.8
        ports:
        - containerPort: 80
          name: web
        volumeMounts:
        - name: www
          mountPath: /usr/share/nginx/html
  volumeClaimTemplates:
  - metadata:
      name: www
    spec:
      accessModes: [ "ReadWriteOnce" ]
      storageClassName: "my-storage-class"
      resources:
        requests:
          storage: 1Gi

给一个示例,以后要配置起码不会没有思路

Deploy

和sts不同,deploy需要进行手动的去声明pv和pvc(如果有provision的话,就只需要写pvc就行)

apiVersion: v1
kind: PersistentVolume
metadata:
  name: pv2
  labels:           #这里将pv设置一个labels
    app: nfs
spec:
  capacity:
    storage: 1Gi
  accessModes:
  - ReadWriteOnce
  persistentVolumeReclaimPolicy: Recycle
  nfs:
    path: /data/k8s-volume
    server: 192.168.1.144
---
apiVersion: v1
kind: PersistentVolumeClaim
metadata:
  name: pvc2-nfs
spec:
  accessModes:
  - ReadWriteOnce
  resources:
    requests:
      storage: 1Gi
  selector:         ##pvc匹配标签为app=nfs的pv
    matchLabels:
      app: nfs

官方文档

apiVersion: apps/v1
kind: Deployment
metadata:
  name: pv-nfs-nginx
spec:
  replicas: 3
  selector:
    matchLabels:
      app: pv-nfs-nginx
  template:
    metadata:
      labels:
        app: pv-nfs-nginx
    spec:
      containers:
      - name: pv-nfs-nginx
        image: nginx
        ports:
        - containerPort: 801
        volumeMounts:           #挂载，首先添加需要挂载的目录
        - name: pv-nginx        #挂载点的名称
          mountPath: /usr/share/nginx/html   #挂载点的路径
      volumes:    #绑定
      - name: pv-nginx
        persistentVolumeClaim:    #将镜像中的nginx目录挂载到下面名称的pvc中
          claimName: pvc2-nfs   #pvc名称
---
apiVersion: v1
kind: Service
metadata:
  name: nfs-pvc
  labels:
    app: pv-nfs-nginx
spec:
  type: NodePort
  ports:
  - port: 80
    targetPort: 80
    nodePort: 324
  selector:
    app: pv-nfs-nginx

上面写的是如何进行声明,使用的话,直接使用pvc的名字绑定就行,一般看一下就懂啥意思了

storageClass

相较于上面写pv和pvc的方式,sc的使用对于用户来说更加便捷,只需要在pvc中声明使用的sc,再写上需要的大小,sc就可以自动创建pv

kind: PersistentVolumeClaim
apiVersion: v1
metadata:
  name: test-claim
spec:
  storageClassName: nfs-client
  accessModes:
    - ReadWriteMany
  resources:
    requests:
      storage: 1Mi
