Chaos Mesh v0.8.0 Release Notes

Chaos Mesh v0.8.0 provides the ability to orchestrate chaos experiments in the Kubernetes environment, with support of comprehensive types of failure simulation, including Pod failures, container failures, network failures, file system failures, system time failures, and kernel failures. Helm installation method is also supported so that users can quickly deploy Chaos Mesh for chaos experiments. Chaos Mesh uses YAML to define chaos experiments, and provides a rich range of preset chaos test samples for users to quickly try Chaos Mesh.

New Features and Enhancements

  • Add PodChaos to simulate the failure on Pods and Containers, including Pods and Containers being killed, Pods being continuously unavailable
