kubernetes-helm - istioctl 安装失败并出现多个超时

Question

按照 istio docs to install the demo profile我收到以下错误。其他人几个月来一直在收到此错误，但没有得到解决。

其他安装方法有效吗？ helm 安装已被弃用，但它仍然有效吗？有没有办法删除我现在的部分安装？

$ istioctl install --set profile=demo

Answer 1

我在另一个主节点上有 32 GB RAM 的 kubernetes 集群上尝试了 istioctl install，它成功了。该集群的创建方式与第一个集群的创建方式相同，主服务器上具有 12 GB RAM，因此允许安装工作的区别在于 RAM 量。

istioctl install 的最低 RAM 要求没有记录，但需要。超时错误消息具有误导性。它应该说RAM不足。还应该有裸机安装的文档。

如果没有足够的 RAM 进行安装，则预检检查不应指示通过。

我希望这对遇到超时消息的其他人有所帮助。
