Chaos Mesh® is a Cloud Native Computing Foundation (CNCF) hosted project. It is a cloud-native Chaos Engineering platform that orchestrates chaos on Kubernetes environments. At the current stage, it has the following components:
- Chaos Operator: the core component for chaos orchestration. Fully open sourced.
- Chaos Dashboard: a Web UI for managing, designing, monitoring Chaos Experiments; under development.
See the following demo video for a quick view of Chaos Mesh:
Chaos Operator injects chaos into the applications and Kubernetes infrastructure in a manageable way, which provides easy, custom definitions for chaos experiments and automatic orchestration. There are three components at play:
Controller-manager: used to schedule and manage the lifecycle of CRD objects
Chaos-daemon: runs as daemonset with privileged system permissions over network, Cgroup, etc. for a specific node
Chaos Operator uses Custom Resource Definition (CRD) to define chaos objects. The current implementation supports six types of CRD objects for fault injection, namely PodChaos, NetworkChaos, IOChaos, TimeChaos, StressChaos, and KernelChaos, which correspond to the following major actions (experiments):
- pod-kill: The selected pod is killed (ReplicaSet or something similar may be needed to ensure the pod will be restarted).
- pod-failure: The selected pod will be unavailable in a specified period of time.
- container-kill: The selected container is killed in the selected pod.
- netem chaos: Network chaos such as delay, duplication, etc.
- network-partition: Simulate network partition.
- IO chaos: Simulate file system faults such as I/O delay, read/write errors, etc.
- time chaos: The selected pod will be injected with clock skew.
- cpu-burn: Simulate the CPU of the selected pod stress.
- memory-burn: Simulate the memory of the selected pod stress.
- kernel chaos: The selected pod will be injected with (slab, bio, etc) errors.

This is a list of known adopters of Chaos Mesh. Some have already gone into production, and others are at various stages of testing.
