Chaos Engineering

Chaos engineering can be used to simulate various types of failures that may occur in a cluster, such as node failures, network partitions, and application failures.

Before introducing chaos into a Kubernetes cluster, it is essential to define the objective of the experiment. This could be to test the resilience of a specific application, identify bottlenecks in the system, or evaluate the effectiveness of a new feature

Tools

These tools allow you to simulate various types of failures and disruptions, such as node outages, network issues, and resource constraints:

  • Chaos Mesh
  • LitmusChaos
  • Chaos Toolkit
  • Kube-Monkey
  • Chaos Kube
