在 vagrantbox (virtualbox) 中将 Dashboard 应用程序部署到 Kubernetes

Question

我正在尝试在 virtualbox 中设置一个 kubernetes 集群。我关注了 https://kubernetes.io/blog/2019/03/15/kubernetes-setup-using-ansible-and-vagrant，到目前为止一切似乎都正常。

但是我无法让仪表板应用程序工作。我遵循了 https://github.com/kubernetes/dashboard and https://github.com/kubernetes/dashboard/blob/master/docs/user/access-control/creating-sample-user.md 的指南，但我无法从我的主机访问 Web-UI。

我的整个设置可以在这里找到：https://github.com/sebastian9486/v-kube-cluster/tree/feature/deploy-dashboard

我的 Vagrantfile 在 src/main/kube-cluster 中，我的 ansible playbook 在 src/main/kube-cluster/kubernetes-setup 中。这些部分目前有效。

在 src/main/kube-cluster/kubernetes-setup/deploy/ 中是 dashboard.sh 部署仪表板应用程序。可能有一些更优雅的方式，但为了知道我试着得到它运行.

安装看起来不错。我的 dashboard.sh

的输出

Answer 1

问题已在评论部分解决，但为了更好的可见性，我决定提供一个答案。

部署 Kubernetes Dashboard 后，要从本地工作站访问它，我们可以通过运行创建到 Kubernetes 集群（我们的机器和 Kubernetes API 服务器之间的代理服务器）的安全通道:

$ kubectl proxy
 Starting to serve on 127.0.0.1:8001

注意： 默认情况下，仪表板只能从启动代理服务器的计算机访问。

仪表板端点可在以下 link 下访问：

http://localhost:8001/api/v1/namespaces/kubernetes-dashboard/services/https:kubernetes-dashboard:/proxy/

了解访问 Kubernetes 仪表板的其他方式（kubectl port-forward, NodePort and Ingress), please visit the Accessing Dashboard documentation。
