aklivity / zilla-examples

A collection of pre-canned Zilla feature demos. Deploy on K8s via Helm.

Zilla Examples

This repo contains a collection of example folders that can be used individually to demonstrate key Zilla features. If this is your first step on your journey with Zilla, we encourage you to try our Quickstart.

Prerequisites

You will need an environment with Docker or Helm and Kubernetes installed. Check out our Postman collections for more ways to interact with an example.

Getting Started

The startup.sh script is meant to help setup and teardown the necessary components for each of the examples. Using it is the easiest way to interact with each example.

Install and run any of the examples using the startup.sh script:

./startup.sh -m example.name

You can specify your own Kafka host and port or the working directory where you want the examples to be downloaded. Existing example directories will not be overwritten.

./startup.sh -m -h kafka -p 9092 -d /tmp example.name

Alternatively, you can run this script the same way without cloning the repo.

wget -qO- https://raw.githubusercontent.com/aklivity/zilla-examples/main/startup.sh | sh -s -- -m example.name

Usage

./startup.sh --help

Usage: startup.sh [-km][-h KAFKA_HOST -p KAFKA_PORT][-d WORKDIR][-v VERSION][--no-kafka][--auto-teardown][--redpanda] example.name
