我一直在寻找一种正确的方法来使用内部负载平衡器对我的内部 vm 规模集进行地形改造，该负载平衡器不会通过公共 IP 暴露于互联网。但是，节点应该可以访问 Internet 以下载位于 github 中的一些包。
我在部署负载均衡器和规模集时遇到了这个问题，但是我没有来自规模集节点的 Internet 带外连接......
我读了这篇文章，但它没有告诉 如何继续
根据我的理解，我应该可以从我的节点访问 Internet 以下载包，因为我使用标准负载均衡器，但它不起作用。
我错过了什么？我宁愿避免使用NAT 网关..
下面是我创建 RG、Vnet 子网、LB 规则以及最后是 VMSS 和 jumbpox 的完整 terraform 脚本。
