Install: brew install pumba

About:
Pumba is a chaos testing command-line tool designed for Docker containers. It enables developers to simulate various failure scenarios, such as resource stress and network disruptions, directly on containerized applications. This helps validate the resilience and stability of microservices under adverse conditions.

Key Features:

Network emulation (delay, loss, duplication)
Resource stress (CPU, memory)
Container lifecycle disruption (pause, stop, kill)
Support for Docker Swarm and Kubernetes
Extensible architecture for custom chaos

Use Cases:

Testing fault tolerance of microservices architectures
Validating container orchestration resilience (e.g., Kubernetes self-healing)
Assessing application performance under network latency or packet loss

Alternatives:

Chaos Mesh – Kubernetes-native platform offering broader chaos experiments but with higher complexity; Pumba is simpler and can target standalone Docker containers.
Litmus – Kubernetes-focused chaos engineering framework with a comprehensive experiment library; Pumba is more lightweight and Docker-centric.
