langep opened a new issue #4550: Dashboard docker shows data only after running pulsar-admin command
URL: https://github.com/apache/pulsar/issues/4550
 
 
   **Describe the bug**
   I am using docker-compose to run pulsar in standalone mode together with dashboard. However, my dashboard stays empty until I run `bin/pulsar-admin clusters list` inside the pulsar container.
   
   **To Reproduce**
   Steps to reproduce the behavior:
   1. Create docker-compose.yaml
   ```
   # docker-compose.yaml
   version: "3.7"
   services:
     apache-pulsar:
       hostname: apache-pulsar
       image: apachepulsar/pulsar:2.3.2
       command: ["bin/pulsar", "standalone"]
       ports:
         - "6650:6650"
         - "8080:8080"
     apache-pulsar-dashboard:
       hostname: apache-pulsar-dashboard
       image: apachepulsar/pulsar-dashboard
       ports:
         - "80:80"
       environment:
         - SERVICE_URL=http://apache-pulsar:8080
   ```
   
   2. Run `docker-compose up`
   3. Go to `http://locahost` and check the dashboard. It does not show data.
   4. Run `docker exec apache-pulsar /bin/bash`
   5. Run `bin/pulsar-admin cluster list` inside the container
   6. The dashboard now shows data (might need a refresh).
   
   **Expected behavior**
   Have the dashboard show data without running a command in the container.
   
   **Desktop (please complete the following information):**
    - OS: macOS but running in docker containers
   
   **Additional context**
   Might be related to #3367
