k8s日志基于nfs持久化配置

1、安装部署NFS服务：

yum -y install nfs-utils rpcbind
systemctl start nfs && systemctl enable nfs
systemctl start rpcbind && systemctl enable rpcbind
mkdir -p /data/volumes/{v1,v2,v3} 
cat > /etc/exports << EOF
/data/volumes/v1  192.168.1.0/24(rw,no_root_squash,no_all_squash)
EOF

2、创建pv

---
apiVersion: v1
kind: PersistentVolume
metadata:
  name: pv-nfs-1
spec:
  capacity: #存储大小
    storage: 100Mi
  accessModes: ["ReadWriteMany","ReadWriteOnce"] #该存储目录允许访问的模式，ReadWriteMany表示可以被多个节点已读写方式挂载，ReadWriteOnce表示可以被一个节点以读写方式挂载
  nfs:
    server: 192.168.1.17
    path: "/data/volumes_test/v1"

3、创建pvc

apiVersion: v1
kind: PersistentVolumeClaim
metadata:
  name: mypvc
  namespace: default
spec:
  accessModes: ["ReadWriteMany"]
  resources:
    requests:
      storage: 100Mi

4、日志目录使用pod名变量

        - name: POD_NAME
          valueFrom:
            fieldRef:
              apiVersion: v1
              fieldPath: metadata.name
        - name: POD_NAMESPACE
          valueFrom:
            fieldRef:
              apiVersion: v1
              fieldPath: metadata.namespace

5、k8s中deploy对象配置持久化

        terminationMessagePolicy: File
        volumeMounts:
        - mountPath: /data/logs
          name: appslogs
          subPathExpr: $(POD_NAMESPACE)/$(POD_NAME)
      dnsPolicy: ClusterFirst
      imagePullSecrets:
      - name: harbor-secret-test
      restartPolicy: Always
      schedulerName: default-scheduler
      securityContext: {}
      terminationGracePeriodSeconds: 30
      volumes:
      - name: appslogs
        persistentVolumeClaim:
          claimName: saas-pvc
