LitmusChaos is an open source Chaos Engineering platform that enables teams to identify weaknesses & potential outages in infrastructures by inducing chaos tests in a controlled way. Developers & SREs can practice Chaos Engineering with Litmus as it is easy to use, based on modern chaos engineering principles & community collaborated. It is 100% open source & a CNCF project.

Litmus takes a cloud-native approach to create, manage and monitor chaos. The platform itself runs as a set of microservices and uses Kubernetes custom resources to define the chaos intent, as well as the steady state hypothesis.

At a high-level, Litmus comprises of:

  • Chaos Control Plane: A centralized chaos management tool called chaos-center, which helps construct, schedule and visualize Litmus chaos workflows
  • Chaos Execution Plane Services: Made up of a chaos agent and multiple operators that execute & monitor the experiment within a defined target Kubernetes environment.

architecture summary

At the heart of the platform are the following chaos custom resources:

  • ChaosExperiment: A resource to group the configuration parameters of a particular fault. ChaosExperiment CRs are essentially installable templates that describe the library carrying out the fault, indicate permissions needed to run it & the defaults it will operate with. Through the ChaosExperiment, Litmus supports BYOC (bring-your-own-chaos) that helps integrate (optional) any third-party tooling to perform the fault injection.

  • ChaosEngine: A resource to link a Kubernetes application workload/service, node or an infra component to a fault described by the ChaosExperiment. It also provides options to tune the run properties and specify the steady state validation constraints using 'probes'. ChaosEngine is watched by the Chaos-Operator, which reconciles it (triggers experiment execution) via runners.

The ChaosExperiment & ChaosEngine CRs are embedded within a Workflow object that can string together one or more experiments in a desired order.

  • ChaosResult: A resource to hold the results of the experiment run. It provides details of the success of each validation constraint, the revert/rollback status of the fault as well as a verdict. The Chaos-exporter reads the results and exposes information as prometheus metrics. ChaosResults are especially useful during automated runs.

ChaosExperiment CRs are hosted on It is a central hub where the application developers or vendors share their chaos experiments so that their users can use them to increase the resilience of the applications in production.


Use cases

  • For Developers: To run chaos experiments during application development as an extension of unit testing or integration testing.
  • For CI/CD pipeline builders: To run chaos as a pipeline stage to find bugs when the application is subjected to fail paths in a pipeline.
  • For SREs: To plan and schedule chaos experiments into the application and/or surrounding infrastructure. This practice identifies the weaknesses in the deployment system and increases resilience.
