@wolfstudy I deployed pulsar referring to
[deploy-kubernetes](http://pulsar.apache.org/docs/en/deploy-kubernetes/), i didn't use helm.
There is only one different step, pulsar-dashboard is deployed with 2.4.1 tag because of [5847](https://github.com/apache/pulsar/issues/5847).

@dockerzhang i can't reproduce your issue.
My step of reproduce:
- cd deployment/kubernetes/helm
- helm install test-pulsar --values ./pulsar/values-mini.yaml ./pulsar
- kubectl exec -it test-pulsar-grafana-5b6db946f9-dprkg -n pulsar /bin/bash
- curl -v http://127.0.0.1:3000/dashboard/file/topic.json?refresh=5s&orgId=1
the output as follows:
```
root@test-pulsar-grafana-5b6db946f9-dprkg:/# curl -v http://127.0.0.1:3000/dashboard/file/topic.json?refresh=5s&orgId=1

@dockerzhang
the yaml files are pretty out-of-dated. It is hard for us to maintain individual yaml files for different platforms. we have decided to remove those yaml files.
Please consider using the latest helm chart for deploying Pulsar on Kubernetes. The Helm chart is now protected and verified using the Helm chart testing framework and it is the official support Helm chart by the Pulsar PMC.
follow the instructions (http://pulsar.apache.org/docs/en/kubernetes-helm/) to get started
follow the instructions to configure (http://pulsar.apache.org/docs/en/helm-deploy/) the helm chart to install a production setup
