OKD Web 容器化安装管理kubevirt虚拟机

        OKD Web 控制台是可从 Web 浏览器访问的用户界面。开发人员可以使用 Web 控制台来可视化、浏览和管理命名空间的内容。它也被称为更友好kubectl的单页 Web 应用程序形式。它与监控、计费和Operator Lifecycle Manager 或 OLM等其他服务集成。幕后发生的一些事情包括：

•  在 /api/kubernetes 下代理 Kubernetes API
•  提供额外的非 Kubernetes API 用于与集群交互
•  提供所有前端静态资产
•  用户认证

        创建一个特定的服务帐户（控制台）来运行 OpenShift Web 控制台，以防之前未创建它并授予集群管理员权限：

$ kubectl create serviceaccount console -n kube-system
$ kubectl create clusterrolebinding console --clusterrole=cluster-admin --serviceaccount=kube-system:console -n kube-system

         提取与控制台服务帐户关联的令牌秘密名称：

$ kubectl get serviceaccount console --namespace=kube-system -o jsonpath='{.secrets[0].name}'
console-token-ppfc2

        修改YAML 文件，为令牌部分分配适当的值。
