Pulsar Dashboard Displays Very Little Information
See original GitHub issueDescribe the bug
The pulsar-dashboard does not display the information published by the pulsar cluster.
To Reproduce Steps to reproduce the behavior:
- Install a bare metal pulsar
- on an openstack cloud
- rather than a DNS server distribute identical /etc/hosts files to each of the vm’s and the development machine
- 3 zookeeper each on their own vm
- 3 bookie/broker each pair on their own vm
- On the development machine: Git clone the pulsar
- build the docker image : docker build -t apachepulsar/pulsar-dashboard dashboard 2: export SERVICE_URL=http://ledge2:8080/ 3: docker run -p 80:80 -e SERVICE_URL=$SERVICE_URL apachepulsar/pulsar-dashboard
- Construct a
- single tenant
- several namespaces
- several topics
Expected behavior The pulsar-dashboard should show clusters, tenants, namespaces, etc.
Screenshots
The pulsar http server shows the presence of the cluster …
The pulsar-dashboard apparently does not know about the cluster…
But no if you bring up one of the tabs having a CLUSTERS menu on the right there is the missing cluster…
Desktop (please complete the following information):
- OS: Ubuntu 18.04 for the development machine and vm’s
Additional context Because /etc/hosts is used instead of DNS it is necessary to use the ledger2 ipaddr.
export SERVICE_URL=http://128.60.107.171:8080/

The problem is with the name lookup. The messages returned by pulsar contain the urls for other objects. Those url contain host names and the docker image has no way of looking them up. This is easily remedied by changing the way the docker image is run.
Note the --network=host parameter. In my case this amounts to granting access to the /etc/hosts files. I would think that this would be the recommended way to run pulsar-dashboard in the “getting started” section of the documentation.
