k8s(Kubernetes)设置 pod，Deployment 域名自定义映射ip,hosts 解析 HostAliases

核心

      hostAliases:
      # 解决服务器内,因路由器配置不全， 不能访问外网问题
        - hostnames:
            - graph.requarks.io
          ip: 104.26.14.122

案例 wiki k8s Deployment

直接 编辑修改 Deployment

kubectl edit Deployment wiki

最后内容如下，如需保存 按 esc 键，最后输入 :wq 保存退出，容器会自动重新生成新的
