Deploy Pulsar on DC/OS


If you want to enable all builtin Pulsar IO connectors in your Pulsar deployment, you can choose to use apachepulsar/pulsar-all image instead of apachepulsar/pulsar image. apachepulsar/pulsar-all image has already bundled all builtin connectors.

DC/OS (the DataCenter Operating System) is a distributed operating system used for deploying and managing applications and systems on Apache Mesos. DC/OS is an open-source tool that Mesosphere creates and maintains .

Apache Pulsar is available as a Marathon Application Group, which runs multiple applications as manageable sets.


In order to run Pulsar on DC/OS, you need the following:

  • DC/OS version 1.9 or higher

  • A DC/OS cluster with at least three agent nodes

  • The DC/OS CLI tool installed

  • The PulsarGroups.json configuration file from the Pulsar GitHub repo.

    $ curl -O

Each node in the DC/OS-managed Mesos cluster must have at least:

  • 4 CPU
  • 4 GB of memory
  • 60 GB of total persistent disk

Alternatively, you can change the configuration in PulsarGroups.json according to match your resources of DC/OS cluster.

Deploy Pulsar using the DC/OS command interface

You can deploy Pulsar on DC/OS using this command:

$ dcos marathon group add PulsarGroups.json

This command deploys Docker container instances in three groups, which together comprise a Pulsar cluster:

When you run DC/OS, a ZooKeeper cluster already runs at master.mesos:2181, thus you do not have to install or start up ZooKeeper separately.

After executing the dcos command above, click on the Services tab in the DC/OS GUI interface, which you can access at http://m1.dcos in this example. You should see several applications in the process of deploying.

The BookKeeper group

To monitor the status of the BookKeeper cluster deployment, click on the bookkeeper group in the parent pulsar group.

DC/OS bookkeeper status

At this point, 3 bookies should be shown as green, which means that the bookies have been deployed successfully and are now running.

DC/OS bookkeeper running

You can also click into each bookie instance to get more detailed information, such as the bookie running log.

DC/OS bookie log

To display information about the BookKeeper in ZooKeeper, you can visit http://m1.dcos/exhibitor. In this example, 3 bookies are under the available directory.

The Pulsar broker Group

Similar to the BookKeeper group above, click into the brokers to check the status of the Pulsar brokers.

DC/OS broker running

You can also click into each broker instance to get more detailed information, such as the broker running log.

DC/OS broker log

Broker cluster information in Zookeeper is also available through the web UI. In this example, you can see that the loadbalance and managed-ledgers directories have been created.

Monitor Group

The monitory group consists of Prometheus and Grafana.

Click into the instance of prom to get the endpoint of Prometheus, which is in this example.

DC/OS prom endpoint

If you click that endpoint, you can see the Prometheus dashboard. The URL display all the bookies and brokers.

DC/OS prom targets


Click into grafana to get the endpoint for Grafana, which is in this example.

If you click that endpoint, you can access the Grafana dashboard.

Run a simple Pulsar consumer and producer on DC/OS

Now that you have a fully deployed Pulsar cluster, you can run a simple consumer and producer to show Pulsar on DC/OS in action.

Download and prepare the Pulsar Java tutorial

You can clone a Pulsar Java tutorial repo. This repo contains a simple Pulsar consumer and producer (you can find more information in the README file of the repo).

$ git clone

Change the SERVICE_URL from pulsar://localhost:6650 to pulsar://a1.dcos:6650 in both and The pulsar://a1.dcos:6650 endpoint is for the broker service. You can fetch the endpoint details for each broker instance from the DC/OS GUI. a1.dcos is a DC/OS client agent, which runs a broker. The client agent IP address can also replace this.

Now, change the message number from 10 to 10000000 in main method of so that it can produce more messages.

Now compile the project code using the command below:

$ mvn clean package

Run the consumer and producer

Execute this command to run the consumer:

$ mvn exec:java -Dexec.mainClass="tutorial.ConsumerTutorial"

Execute this command to run the producer:

$ mvn exec:java -Dexec.mainClass="tutorial.ProducerTutorial"

You can see the producer producing messages and the consumer consuming messages through the DC/OS GUI.

View Grafana metric output

While the producer and consumer run, you can access running metrics information from Grafana.

Uninstall Pulsar

You can shut down and uninstall the pulsar application from DC/OS at any time in the following two ways:

  1. Using the DC/OS GUI, you can choose Delete at the right end of Pulsar group.

    DC/OS pulsar uninstall

  2. You can use the following command:

    $ dcos marathon group remove /pulsar
