Spark Kubernetes构建docker镜像失败

我在Kubernetes上试Spark。刚刚在我的VPC中的EC2实例上下载了Spark 2.4.3。我已经在/etc/sysconfig/docker中设置了我的代理，并且能够从docker hub导入和运行docker映像

命令：bin/docker-image-tool.sh-t k8s-spark-2.4.3 build

你知道怎么解决这个问题吗？

我也试着在“docker登录”后运行这个。结果是一样的

您的EC2实例似乎与internet没有连接

我在笔记本电脑上运行的Ubuntu 16.04虚拟机中遇到了完全相同的问题

我能够用curl下载软件包，并使用web浏览器访问alpine存储库目录，因此我知道问题不在于网络连接

信不信由你，解决方案是重新启动虚拟机中运行的docker服务

我在搜索apline软件包加载错误时发现这是一个建议的解决方案，它成功了

它有互联网连接。它位于proxy的后面，但我确实按照我的问题中提到的设置了proxy。@VenkatAnkam您为dockerhub指定了一个代理，而不是AlpineLinux Packages的代理dockerhub的代理或任何其他代理都是相同的，对吗？您不需要

docker登录

。错误只是说从$base\u img执行

时找不到第一个容器映像
spark
，这是因为它没有构建（因为无法访问Alpine linux repos）
