Chaos Engineering - How to simulate I/O faults at runtime

In a production environment, filesystem faults might occur due to various incidents such as disk failures and administrator errors. As a Chaos Engineering platform, Chaos Mesh has supported simulating I/O faults in a filesystem ever since its early versions. By simply adding an IOChaos CustomResourceDefinition (CRD), we can watch how the filesystem fails and returns errors.

chaos-mesh-action: Integrate Chaos Engineering into Your CI

chaos-mesh-action - Integrate Chaos Engineering into Your CI

Chaos Mesh is a cloud-native chaos testing platform that orchestrates chaos in Kubernetes environments. While it’s well received in the community with its rich fault injection types and easy-to-use dashboard, it was difficult to use Chaos Mesh with end-to-end testing or the continuous integration (CI) process. As a result, problems introduced during system development could not be discovered before the release.

In this article, I will share how we use chaos-mesh-action, a GitHub action to integrate Chaos Mesh into the CI process.

Building an Automated Testing Framework Based on Chaos Mesh® and Argo

TiPocket - Automated Testing Framework

Chaos Mesh® is an open-source chaos engineering platform for Kubernetes. Although it provides rich capabilities to simulate abnormal system conditions, it still only solves a fraction of the Chaos Engineering puzzle. Besides fault injection, a full chaos engineering application consists of hypothesizing around defined steady states, running experiments in production, validating the system via test cases, and automating the testing.

This article describes how we use TiPocket, an automated testing framework to build a full Chaos Engineering testing loop for TiDB, our distributed database.

Simulating Clock Skew in K8s Without Affecting Other Containers on the Node

Clock synchronization in distributed system

Chaos Mesh™, an easy-to-use, open-source, cloud-native chaos engineering platform for Kubernetes (K8s), has a new feature, TimeChaos, which simulates the clock skew phenomenon. Usually, when we modify clocks in a container, we want a minimized blast radius, and we don't want the change to affect the other containers on the node. In reality, however, implementing this can be harder than you think. How does Chaos Mesh solve this problem?

Run your first chaos experiment in 10 minutes

Chaos Engineering is a way to test a production software system's robustness by simulating unusual or disruptive conditions. For many people, however, the transition from learning Chaos Engineering to practicing it on their own systems is daunting. It sounds like one of those big ideas that require a fully-equipped team to plan ahead. Well, it doesn't have to be. To get started with chaos experimenting, you may be just one suitable platform away.
