Litmus
Litmus is an open-source tool for testing and validating Kubernetes deployments, focusing on chaos engineering to ensure resilience and reliability of cloud-native applications. It provides a framework to inject controlled failures into Kubernetes environments, helping teams identify weaknesses and improve system robustness. Originally developed by MayaData and now part of the Cloud Native Computing Foundation (CNCF), it integrates with Kubernetes-native resources like Custom Resource Definitions (CRDs) for seamless operation.
Developers should learn Litmus when building or maintaining Kubernetes-based applications that require high availability and fault tolerance, such as microservices architectures or critical production systems. It is particularly useful for implementing chaos engineering practices to proactively test system resilience against failures like pod crashes, network latency, or resource constraints, reducing downtime risks. Use cases include validating disaster recovery plans, compliance with service-level agreements (SLAs), and improving DevOps workflows through automated chaos experiments.
