用kubernetes

Question

我尝试用Couchbase实现Spring Boot的示例。实施Docker流程后，我通过了Kubernetes。

我在启动Minikube并打开仪表板后运行

kubectl apply -f k8s

命令时会有一些问题。
couchbase抛出了下面所示的这个问题

Failed to pull image "couchbase:latest": rpc error: code = Unknown desc = context deadline exceeded

该应用程序名为TodowithCouchbase抛出了下面所示的此问题Failed to pull image "noyandocker/todowithcouchbase:latest": rpc error: code = Unknown desc = context deadline exceeded

可以通过此
