Maybe it's a JDK bug, and I can avoid this by adding -XX:UseSSE=2 to JAVA_TOOL_OPTIONS temporarily

请问下，按照 readme.md 克隆到本地，按照构建命令构建，skaffold dev 报错如上，需要做什么配置吗？
以下是按照构建部分输出：

bookstore-microservices-platform-gateway服务启动不了

周老师好，通过下面的命令启动整个集群：

kubectl apply -f bookstore.yml

其他都显示正常启动，就是bookstore-microservices-platform-gateway服务启动不了，是不是这个镜像有问题？因为我看到这个镜像的下载次数比其他镜像的多一倍。

基于minikube环境:

[root@k8s microservice_arch_kubernetes]# minikube version
minikube version: v1.7.2
commit: 50d543b5fcb0e1c0d7c27b1398a9a9790df09dfb

pod的日志如下：

[root@k8s microservice_arch_kubernetes]# kubectl logs bookstore-microservices-platform-gateway-84b7c776dd-k2sd4  -n bookstore-microservices
