kubernetes - 无法公开部署 Kubernetes 仪表板 (HTTPS)

问题描述

我是 kubernetes 的新手，经过很长时间的研究，似乎我的资源已经用完了，所以如果有人可以帮助我，我会非常高兴。

我目前拥有的

入口资源（仪表板）：

命名空间 姓名 班级 主机 地址 端口 年龄
Kubernetes-仪表板 仪表板入口 仪表盘.k8s.mydomain.de 10.10.1.164 80 52m

当我尝试使用https://dashboard.k8s.mydomain.de没有任何反应到达 kubernetes 仪表板时。当我尝试使用https://dashboard.k8s.mydomain.de:30710nginx 入口控制器的 HTTPS TCP 端口来访问它时，它就可以工作了。它是一个不安全的连接，浏览器会警告我，但它可以工作。但显然这不是期望的行为。

我想拥有什么

我想以某种方式部署 kubernetes 仪表板，以便https://dashboard.k8s.mydomain.de通过 HTTPS 访问 kubernetes 仪表板。我不知道为什么目前情况并非如此。

这些是.yaml我用于部署和东西的配置文件：

apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
  name: dashboard-ingress
  namespace: kubernetes-dashboard
  annotations:
    nginx.ingress.kubernetes.io/backend-protocol: HTTPS
spec:
  rules:
    - host: dashboard.k8s.mydomain.de
      http:
        paths:
          - path: /
            pathType: Prefix
            backend:
              service:
                name: kubernetes-dashboard
                port:
                  number: 443

nginx入口控制器的日志告诉我它注册了入口资源，所以我很困惑：

当我使用 microk8s 而不是 kubeadm 设置集群时，它可以工作。请指定我必须做什么才能完成这项工作。

解决方案

请在 hostNetwork 模式下运行 nginx 入口控制器https://kubernetes.github.io/ingress-nginx/deploy/baremetal/#via-the-host-network

template:
  spec:
    hostNetwork: true

并将其作为 DaemonSet 运行。

并将 dnsPolicy 设置为 ClusterFirstWithHostNet

另外，请阅读https://kubernetes.github.io/ingress-nginx/deploy/baremetal/#via-the-host-network中的安全警告

如果您使用的是https://kubernetes.github.io/ingress-nginx/deploy/#using-helm然后将下面添加到值文件

controller:
  dnsPolicy: ClusterFirstWithHostNet
  hostNetwork: true
  kind: DaemonSet
