将glusterfs存储同时挂载到initContainer和container的指定目录上，如：/var/data/在initContainer中拉取资源放到/var/data/，也就推到了分布式存储glusterfs上，如：wget -P /var/data/ http://127.0.0.1:8081/repository/k8s/kubectl/kubectl-v1.10.0-linux-amd64.tar.gz这样当业务容器启动后，就可以在指定目录/var/data下看到initContainer拉取到的资源在initContainer中，最好增加一部检测指定资源是否存在，以防重复拉取，如：if [ ! -f “/var/data/kubectl-v1.10.0-linux-amd64.tar.gz” ]; then wget -P /var/data/ http://127.0.0.1:8081/repository/k8s/kubectl/kubectl-v1.10.0-linux-amd64.tar.gz; fiapiVersion: apps/v1kind: Deploymentmetadata: name: mysqlspec: replicas: 1 selector: matchLabels: name: mysql template: metadata: labels: name: mysql spec: initContainers: - name: getresource image: busybox:v0.1.0 command: [‘sh’, ‘-c’, ‘wget -P /var/data/ http://127.0.0.1:8081/repository/k8s/kubectl/kubectl-v1.10.0-linux-amd64.tar.gz ‘] volumeMounts: - name: mysql-pvc mountPath: /var/data containers: - name: mysql image: percona:5.7.22 imagePullPolicy: Always ports: - containerPort: 3306 resources: limits: memory: “500Mi” cpu: “500m” requests: memory: “500Mi” cpu: “250m” env: - name: MYSQL_ROOT_PASSWORD value: “mysql” volumeMounts: - name: mysql-pvc mountPath: /var/data volumes: - name: mysql-pvc persistentVolumeClaim: claimName: mysql—apiVersion: v1kind: PersistentVolumeClaimmetadata: name: mysqlspec: accessModes: - ReadWriteMany resources: requests: storage: “5Gi” volumeName: storageClassName: glusterfs—kind: ServiceapiVersion: v1metadata: name: mysqlspec: type: ClusterIP ports: - name: mysql port: 3306 targetPort: 3306 protocol: TCP selector: name: mysql
