chaosd
What it is
chaosd is a free Chaos Engineering tool for injecting faults into physical machine environments and recovering from experiments. It supports process, network, CPU or memory pressure, disk, and host faults. It can run 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 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 by UID. The plan costs nothing, and 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.
For and against
For
- Supports process, network, CPU, memory, disk, and host faults.
- Can run as a CLI or HTTP-controlled background service.
- Experiments can be recovered by UID.
- Apache-2.0 licensed and free.
Against
- The documented binary download is for Linux amd64.
- Network experiments may require sudo or root privileges.
- Does not provide Kubernetes support or cloud fault injection.
- Experiment scheduling is not provided.
The verdict
chaosd offers command-line and service-mode fault injection for physical machine environments, with experiment recovery by UID. Its Linux requirements, separate deployment from Chaos Mesh, and missing Kubernetes, cloud, and scheduling support shape where it fits.
Who it suits
chaosd suits users who need to inject and recover faults in physical or virtual machine environments. It requires Linux, glibc 2.17 or later, and elevated privileges for network experiments using tc or iptables.
