chaosd
chaosd is a free Chaos Engineering tool for injecting faults into physical machine environments and recovering from experiments.
What chaosd is
chaosd is a free Chaos Engineering tool for injecting faults into physical machine environments and recovering from experiments. It can create process, network, CPU or memory pressure, disk, and host faults. It runs either as a command-line tool or as a background service controlled through HTTP requests. Chaosd is deployed separately from Chaos Mesh; PhysicalMachineChaos experiments require it to run in service mode on each targeted physical or virtual machine. The documented operating environment requires glibc 2.17 or later, and the documented binary download is a Linux amd64 tarball. Network experiments using tc or iptables require sudo or root privileges. The repository lists tc, ipset, and iptables as deployment prerequisites; source builds also require stress-ng and byteman. Chaosd can find experiments and recover them using their UIDs. The repository identifies the license as Apache-2.0. It supports network fault injection and blast-radius controls, but does not provide Kubernetes support, cloud fault injection, or experiment scheduling.
Good
- Injects process, network, disk, and host faults.
- Can run as a CLI or HTTP-controlled service.
- Supports finding and recovering experiments by UID.
- Free and Apache-2.0 licensed.
Watch out
- Documented binary download is for Linux amd64.
- Requires glibc 2.17 or later.
- Network experiments need sudo or root privileges.
- Does not provide Kubernetes or cloud fault injection.
Who it suits
chaosd suits teams running Chaos Engineering experiments on physical or virtual machines, especially those using Chaos Mesh PhysicalMachineChaos. It is intended for Linux environments that meet its documented requirements.
Verdict
chaosd provides a focused way to inject and recover physical-machine faults, including through Chaos Mesh PhysicalMachineChaos. Check its Linux environment, prerequisites, and privilege requirements before deployment.
