## What it is
Pumba is a chaos testing and network emulation CLI tool for Docker, containerd, and Podman containers. It can kill, stop, pause, or remove containers, inject network delays and packet loss, and stress-test container resources.

## Use cases
- inject network latency into docker containers
- chaos test kubernetes pods by killing containers
- simulate packet loss between services
- stress test container cpu and memory
- verify service resilience to random container failures
- emulate slow networks for containerized apps

## When to choose
- you practice chaos engineering on containerized workloads
- you need network fault injection for Docker, containerd, or Podman
- you want a Netflix Chaos Monkey-style tool at the container level

## When to avoid
- you need chaos testing for non-containerized hosts or VMs
- you want a managed chaos platform with dashboards and experiments UI
- your environment disallows privileged helper containers or root access
