我们在之前的（安装和构建ci）实践中，用到都是tekton cli，查看ci执行情况都是通过logs，不是很友好。 tekton dashboard提供了很多的ui界面。这里我们来安装并使用。

1. 创建dashboard.yaml

2. 安装dashboard

kubectl apply -f dashboard.yaml 

3. 查看dashboard

kubectl get deploy -n tekton-pipelines | grep dashboard
kubectl get svc -n tekton-pipelines | grep dashboard

我的输出为：

carawang@ci %kubectl get svc -n tekton-pipelines | grep dashboard
tekton-dashboard                    LoadBalancer   10.103.207.156   <pending>     9097:30755/TCP                       4m52s

因为我用的是minikube，没有endpoint可以供访问，需要forward一下。

4. forward dashboard

kubectl port-forward -n tekton-pipelines service/tekton-dashboard 9097:9097

不报错的话，就可以访问http://localhost:9097

5. 查看pipelineruns等

可以看到界面很友好。
