5.7 部署istio dashboard

Naftis 是一个基于 web 的 Istio dashboard，通过任务模板的方式来帮助用户更方便地执行 Istio 任务。 用户可以在 Naftis 中定义自己的任务模板，并填充变量来构造单个或多个构造任务实例，从而完成各种服务治理功能。

Naftis的功能：

• 内部集成了一些常用 dashboard

• 可定制的任务模板支持

• 支持回滚指定任务

• 支持指定根服务节点的服务拓扑图

• 提供查看 Istio 的 Services 和 Pod 的支持

• 开箱即用，通过 Kubectl 相关指令即可快速部署

• 支持 Istio 1.0

configmap/naftis-mysql-test created
persistentvolumeclaim/naftis-mysql created
service/naftis-mysql created
pod/naftis-mysql-test created
deployment.apps/naftis-mysql created

确认 MySQL 已部署

kubectl get po -n naftis
NAME                           READY   STATUS    RESTARTS   AGE
naftis-mysql-54444ffc5-7mp86   1/1     Running   0          33s
naftis-mysql-test              0/1     Running   0          33s

部署 Naftis API 和 UI 服务

kubectl apply -n naftis -f naftis.yaml
namespace/naftis created
configmap/naftis-config created
clusterrolebinding.rbac.authorization.k8s.io/naftis-rbac created
service/naftis-api created
service/naftis-ui created
deployment.apps/naftis-ui created
deployment.apps/naftis-api created

确认 Naftis 所有的服务已经正确定义并正常运行中

kubectl get svc -n naftis
NAME           TYPE           CLUSTER-IP       EXTERNAL-IP   PORT(S)        AGE
naftis-api     ClusterIP      10.104.140.162   <none>        50000/TCP      27s
naftis-mysql   ClusterIP      10.105.179.76    <none>        3306/TCP       79s
naftis-ui      LoadBalancer   10.97.7.57       <pending>     80:30377/TCP   27s

kubectl get pod -n naftis
NAME                           READY   STATUS    RESTARTS   AGE
naftis-api-7cbdb88f97-qrg2f    0/1     Running   0          6s
naftis-mysql-54444ffc5-8vnsq   1/1     Running   0          58s
naftis-mysql-test              0/1     Running   0          58s
naftis-ui-5f769cdbbd-85cwz     1/1     Running   0          6s

端口转发访问 Naftis

kubectl -n naftis port-forward $(kubectl -n naftis get pod -l app=naftis-ui -o jsonpath='{.items[0].metadata.name}') --address 0.0.0.0 8080:80 &

打开浏览器，访问 http://localhost:8080 即可。默认用户名和密码分别为 admin、admin。

或者修改naftis-ui服务类型为NodePort

kubectl patch -n naftis svc naftis-ui -p '{"spec": {"type": "NodePort"}}'
service/naftis-ui patched

kubectl get svc -n naftis naftis-ui
NAME        TYPE       CLUSTER-IP   EXTERNAL-IP   PORT(S)        AGE
naftis-ui   NodePort   10.97.7.57   <none>        80:30377/TCP   6m39s

然后通过http://192.168.100.10:30377进行访问。

页面支持中文和英文两种，具体的操作略。
