Harnessing Chaos Testing in Vald: A Comprehensive Guide to the Vald-Chaos-Test Helm Chart

Jul 6, 2025

Introduction to Vald and Chaos Testing

Vald is an advanced vector search engine designed for high-performance applications. In the realm of cloud-native applications, ensuring resilience against failures is crucial. This is where chaos testing comes into play. By simulating failures, developers can identify weaknesses in their systems and improve overall reliability.

What is the Vald-Chaos-Test Helm Chart?

The Vald-Chaos-Test Helm chart provides a structured way to implement chaos testing on Vald deployments using Chaos Mesh. This chart allows developers to simulate various failure scenarios, such as network issues and pod failures, to ensure that their applications can withstand unexpected disruptions.

Main Features of Vald-Chaos-Test

  • Network Chaos: Simulate network bandwidth limitations and partitions.
  • Pod Chaos: Test the resilience of your application by simulating pod failures and terminations.
  • Customizable Parameters: Adjust chaos parameters such as duration, bandwidth, and failure rates to suit your testing needs.
  • Easy Integration: Seamlessly integrate with existing Vald deployments using Helm.

Technical Architecture and Implementation

The Vald-Chaos-Test Helm chart is structured to work with Kubernetes and Chaos Mesh. It leverages Kubernetes resources to create chaos experiments that can be easily managed and monitored. The chart includes configurations for various chaos scenarios, allowing developers to customize their testing environments.

Setup and Installation Process

To get started with the Vald-Chaos-Test Helm chart, follow these steps:

  1. Ensure you have Helm and Chaos Mesh installed in your Kubernetes cluster.
  2. Add the Vald Helm repository:
  3. helm repo add vald https://github.com/vdaas/vald
  4. Install the Vald-Chaos-Test chart:
  5. helm install vald-chaos-test vald/vald-chaos-test

Usage Examples and API Overview

Once installed, you can configure chaos experiments using the provided values in the Helm chart. Here’s an example of how to enable network chaos:

networkChaos:
  enabled: true
  bandwidth:
    limit: 100
    duration: "100ms"

This configuration simulates a network bandwidth limit of 100 units for a duration of 100 milliseconds.
