安装 Ingress Controller

ingress官方文档：https://kubernetes.io/docs/concepts/services-networking/ingress/

Ingress Controllers官网介绍：https://kubernetes.io/docs/concepts/services-networking/ingress-controllers/

本文中使用如下部署方式：https://kubernetes.github.io/ingress-nginx/deploy/baremetal/#using-a-self-provisioned-edge

kubernetes支持多种Ingress Controllers，本文推荐使用

https://github.com/nginxinc/kubernetes-ingress

在 apple-master-a-1 上执行

su - gitlab-runner
 kubectl apply -f https://raw.githubusercontent.com/eip-work/eip-monitor-repository/master/dashboard/nginx-ingress.yaml

在IaaS云控制台完成如下配置（公网ELB）

创建负载均衡 ELB：

​ 监听器 1：80 / TCP， SOURCE_ADDRESS 会话保持

​ 服务器资源池 1： apple-worker-x-x 的所有节点的 80端口

​ 监听器 2：443 / TCP， SOURCE_ADDRESS 会话保持

​ 服务器资源池 2： apple-worker-x-x 的所有节点的443端口

假设刚创建的负载均衡 ELB 的 IP 地址为： z.z.z.z

配置域名解析

将域名 *.apple.yourdomain.com 解析到地址负载均衡服务器 的 IP 地址 z.z.z.z

验证配置

在浏览器访问 a.apple.yourdomain.com，将得到 404 NotFound 错误页面

  • 避免重复执行对测试机安装必要软件的过程
  • 以一种相对标准化的过程管理测试机的维护

标准机镜像中预装了如下内容：

  • docker
  • nfs-utils
  • kubernetes images
  • 您也可以不制作标准机镜像，而是在三台机器上都执行 制作标准机镜像 中的所有操作步骤

    纯图形界面运维 Kubernetes

    在作者的日常运维工作中，除了 kubectl port-forward 还需要回到命令行界面以外，其他运维任务已经全部在 Kuboard 中轻松完成。更让人期待的是，Kuboard 作者还计划实现 port-forward 的功能，如此一来，作者日后就完全不再需要使用 kubectl 了。
