In this blog, we dive into real-world chaos engineering scenarios using LitmusChaos, an open-source tool for testing Kubernetes resilience. We explore three key experiments: simulating network latency on an NGINX application, generating high load with the k6-loadgen experiment, and inducing memory pressure on a node using the node-memory-hog fault. These practical examples demonstrate how LitmusChaos can uncover vulnerabilities in your Kubernetes setup, ensuring your applications are prepared for unexpected failures. Learn how to implement these experiments and monitor the results with Grafana dashboards.
