puls

puls is a CLI tool that allows you to run a local Pulsar instance with different configurations.

The motivation is to minimize the entry threshold for Pulsar novices and quickly try different Puslar features without spending much time.

Usage

puls start

Requirements

• Installed Docker >= 2.24.0
• Enough computing resources. For Docker Desktop, you can adjust available resources by following these instructions.

You can take the following numbers as a basis:

• A cluster with 1 broker and 1 bookie needs 1 CPU core and 1GB RAM.
• A cluster with 3 brokers and 3 bookies needs 1.5-2 CPU cores and 3GB RAM.

For example, you'll need about 3-4CPU cores and 6GB RAM for the following Pulsar instance with two clusters:

puls create --num-clusters 2 --num-bookies 3 --num-brokers 3 multi-cluster

Planned features

• Minio S3 to demonstrate the Pulsar tiered storage feature
• Postgres to demonstrate Pulsar IO
• Dekaf UI as Pulsar management UI
• Monitoring stack - Prometheus, Grafana
