Pulsar 仪表板是一个网页应用程序，使用户能够以表格形式监测所有 主题 的实时状态。
The dashboard is a data collector that polls stats from all the brokers in a Pulsar instance (across multiple clusters) and stores all the information in a PostgreSQL database.
A Django web app is used to render the collected data.
使用dashboard的最简单方法是在 Docker 容器中运行它。
SERVICE_URL=http://broker.example.com:8080/ docker run -p 80:80 \ -e SERVICE_URL=$SERVICE_URL \ apachepulsar/pulsar-dashboard:2.4.2
can be found in
dashboard directory, you can build a image from scratch also:
docker build -t apachepulsar/pulsar-dashboard dashboard
If token authentication is enabled:
Provided token should have super-user access.
SERVICE_URL=http://broker.example.com:8080/ JWT_TOKEN=eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJzdWIiOiIxMjM0NTY3ODkwIiwibmFtZSI6IkpvaG4gRG9lIiwiaWF0IjoxNTE2MjM5MDIyfQ.SflKxwRJSMeKKF2QT4fwpMeJf36POk6yJV_adQssw5c docker run -p 80:80 \ -e SERVICE_URL=$SERVICE_URL \ -e JWT_TOKEN=$JWT_TOKEN \ apachepulsar/pulsar-dashboard
You need to specify only one service URL for a Pulsar cluster. Internally, the collector will figure out all the existing clusters and the brokers from where it needs to pull the metrics. If you're connecting the dashboard to Pulsar running in standalone mode, the URL will be
http://<broker-ip>:8080 by default.
<broker-ip> is the ip address or hostname of the machine running Pulsar standalone. The ip address or hostname should be accessible from the docker instance running dashboard.
Once the Docker container is running, the web dashboard will be accessible via
localhost or whichever host is being used by Docker.
If the Pulsar service is running in standalone mode in
SERVICE_URL would have to be the IP of the machine.
Similarly, given the Pulsar standalone advertises itself with localhost by default, we need to explicitely set the advertise address to the host IP. 例如:
bin/pulsar standalone --advertised-address 22.214.171.124
Only Pulsar Token authentication is supported as of now.
