    Istio 和几个遥测应用做了集成。 遥测能帮你了解服务网格的结构、展示网络的拓扑结构、分析网格的健康状态。
    使用下面说明部署 Kiali 仪表板、 以及 Prometheus、 Grafana、 还有 Jaeger。

    1、安装 Kiali 和其他插件,等待部署完成

    [root@k8s-master ~]# cd /usr/local/istio-1.15.6
    [root@k8s-master istio-1.15.6]# kubectl apply -f samples/addons
    [root@k8s-master istio-1.15.6]# kubectl rollout status deployment/kiali -n istio-system

    2、访问 Kiali 仪表板

    [root@k8s-master istio-1.15.6]# istioctl dashboard kiali --address 192.168.1.59 -p 20001

    http://192.168.1.59:20001/kiali
    Failed to open browser; open http://192.168.1.59:20001/kiali in your browser.

    此时创建的 service 不提供外部访问,我们修改 service 来暴露 NodePort 以支持外部访问

    [root@k8s-master istio-1.15.6]# kubectl -n istio-system edit svc kiali

    在 spec.ports 的 http 节点添加 nodePort: 31001,并且修改 spec.type 的值为 NodePort,保存退出后配置生效即可通过 nodePort 端口访问 Kiali

    [root@k8s-master istio-1.15.6]# kubectl -n istio-system edit svc kiali
    # Please edit the object below. Lines beginning with a '#' will be ignored,
    # and an empty file will abort the edit. If an error occurs while saving this file will be
    # reopened with the relevant failures.
