Pumba is a chaos testing and network emulation tool for Docker, containerd, and Podman containers. Inspired by [Netflix Chaos Monkey](https://netflix.github.io/chaosmonkey/), Pumba brings chaos engineering to the container level — kill, stop, pause, and remove containers, inject network delays and packet loss, or stress-test container resources.
## How It Works
```mermaid

A[Pumba CLI] -->|Docker API / containerd API / Podman compat API| B[Container Runtime]

```
### Supported runtimes
| Runtime | Socket (default) | netem / iptables / stress | Notes |
| ---------- | ----------------------------------- | --------------------------------------------- | --------------------------------------------------------------------------------------------- |
| Docker | `/var/run/docker.sock` | Works as root or with socket access | Default runtime. |
| containerd | `/run/containerd/containerd.sock` | Requires root (overlayfs mounts for sidecar) | Namespaces: `k8s.io` (Kubernetes), `moby` (Docker-managed), `default` (pure containerd). |
| Podman | `/run/podman/podman.sock` (rootful) | Requires **rootful** Podman (fails fast else) | Uses Podman's Docker-compat API; on macOS pumba runs **inside `podman machine`** (see below). |
### Supported platforms
Pumba targets **Linux containers** — every chaos action depends on Linux primitives (netns, cgroups v2, iptables, tc qdiscs, container runtime sockets). Released binaries:
| OS | amd64 | arm64 | Notes |
| ------- | :---: | :---: | -------------------------------------------------------------------------------------------------------------- |
| Linux | ✅ | ✅ | Primary target. Run pumba on the same kernel as the targeted containers. |
| macOS | ✅ | ✅ | Developer ergonomics only. Use it to drive a remote Docker/Podman/containerd VM (e.g. Colima, podman machine). |
| Windows | ❌ | ❌ | **Not supported and not planned.** See Excerpt of 11,862 characters
