kubeup / hostroutes Goto Github PK

For master servers behind load balancer, pods cannot connect to the load balancer. So we have to add an option to support connecting to local apiserver.

hostroutes 只是个单机软件. 我最近写了个 pikeszfish/simplest-cni 里面参考了部分/许多 kubeup/hostroutes 的实现. 并将其实现/扩展为 k8s 下的 CNI.

因为没能看到 kubeup/hostroutes 的许可证, 也不是十分了解 kubeup 这个组织, 我在项目中用了 GNU General Public License v3.0. Is that cool?

on all nodes hostroutes display error:
