Pulsar command-line tools

Pulsar offers several command-line tools that you can use for managing Pulsar installations, performance testing, using command-line producers and consumers, and more.

All Pulsar command-line tools can be run from the bin directory of your installed Pulsar package. The following tools are currently documented:

pulsar
pulsar-client
pulsar-daemon
pulsar-perf
bookkeeper
broker-tool

Getting help

You can get help for any CLI tool, command, or subcommand using the --help flag, or -h for short. Here's an example:

$ bin/pulsar broker --help

`pulsar`

The pulsar tool is used to start Pulsar components, such as bookies and ZooKeeper, in the foreground.

These processes can also be started in the background, using nohup, using the pulsar-daemon tool, which has the same command interface as pulsar.

Usage:

$ pulsar command

Commands:

bookie
broker
compact-topic
discovery
configuration-store
initialize-cluster-metadata
proxy
standalone
websocket
zookeeper
zookeeper-shell

Example:

$ PULSAR_BROKER_CONF=/path/to/broker.conf pulsar broker
