Kubernetes反复拉图像，并坚持创build容器
我试图创build一个单实例有状态的应用程序的行https://kubernetes.io/docs/tasks/run-application/run-single-instance-stateful-application/ ，除了我想使用Oracle数据库。
我运行W10并使用Minikube来设置群集，Hyper-V作为驱动程序，并且我还为Minikube创build了一个虚拟交换机。
我相应地编辑了部署YAML以使用Oracle数据库镜像和端口，并为Docker Hub添加了一个拉密（因为Oracle希望您login以拉取图像）。
最后的YAML：
apiVersion: v1 kind: Service metadata: name: orcldb spec: ports: - port: 1521 name: sqlnet - port: 5500 name: oraclexml selector: app: orcldb clusterIP: None --- apiVersion: v1 kind: PersistentVolumeClaim metadata: name: orcldb-pv-claim spec: accessModes: - ReadWriteOnce resources: requests: storage: 5Gi --- apiVersion: apps/v1beta2 kind: Deployment metadata: name: orcldb spec: selector: matchLabels: app: orcldb strategy: type: Recreate template: metadata: labels: app: orcldb spec: containers: - image: store/oracle/database-enterprise:12.2.0.1 name: orcldb ports: - containerPort: 1521 name: sqlnet - containerPort: 5500 name: oraclexml volumeMounts: - name: orcldb-persistent-storage mountPath: /var/lib/orcldb imagePullSecrets: - name: dockerhubkey volumes: - name: orcldb-persistent-storage persistentVolumeClaim: claimName: orcldb-pv-claim 所以，我运行kubectl create -f deployment.yaml ，一切都相应地创build：
service "orcldb" created persistentvolumeclaim "orcldb-pv-claim" created deployment "orcldb" created
但是，如果我运行kubectl describe pods orcldb ，我在事件中看到这一点：

另外，minikube集群有时会停止（？）/拒绝连接，之后我通常会重新启动minikube，但是一旦我离开它，它会在一段时间后恢复（重复拔出过程仍在继续）。
我一直没能find任何人面对这样的问题，所以我非常感谢为什么会发生这种情况。
部分minikube日志中有关磁盘的错误：

我从Oracle的巨大官方图像中移除，并使用Oracle Express 11g数据库的自定义映像。 图像现在被拉出，容器开始没有任何问题。
此外，Minikube在一段时间后会停止响应的问题可以通过在Hyper-V中禁用dynamic内存来解决，如本github问题中所述 。
