About Pumba

Pumba injects chaos into Docker, containerd, and Podman containers by killing, stopping, pausing, or removing them, applying network conditions, and stressing resources.

It targets Linux containers and their Linux networking and system features. On macOS, it can drive containers in a remote VM such as Colima or podman machine.

Strengths

Supports Docker, containerd, and Podman
Can test container failure and network scenarios
Includes resource stress testing

Limitations

Targets Linux containers; on macOS, it must drive a remote container VM.
Some container runtime operations require root or socket access.
