我已经按照以下步骤设置了Kubernetes。一切看起来都很好 - 但它在单个节点/服务器上运行。
现在我想采取下一步在多个节点上运行。我想知道我应该在哪里配置我的物理服务器ip，这样我就可以在多个物理服务器上创建pod。
我跑：
hack/local-up-cluster.sh
然后（在另一个终端）：
cluster/kubectl.sh config set-cluster local --server=http://127.0.0.1:8080 --insecure-skip-tls-verify=true
cluster/kubectl.sh config set-context local --cluster=local
cluster/kubectl.sh config use-context local
并且：
cluster/kubectl.sh create -f run-aii.yaml
我的run-aii.yaml：

答案 0 :(得分：1)
听起来您想要设置多节点群集，有很多方法可以做到这一点（http://kubernetes.io/docs/getting-started-guides/）。
如果你想在你的机器上使用本地解决方案，那么流浪者或者码头工作方式非常简单。
如果要寻找云，那么GCE是下一个最简单的（https://cloud.google.com/container-engine/）。
一旦设置了多节点群集，那么在部署pod时，它将被安排到群集中的节点。
唯一的 gotcha 要注意上面的清单，您是否正在使用HostPaths进行所有卷安装。当您知道正在运行pod的机器时，这很好，但是，您应该将自己抽象出来。
为了更好地解决您，您需要查看一些非特定于主机的持久性卷。但是现在，你可以让它运作起来。 =）
