Litmus helps SREs and developers practice chaos engineering in a Cloud-native way. Chaos experiments are published at the ChaosHub (https://hub.litmuschaos.io). Community notes is at https://hackmd.io/a4Zu_sH4TZGeih-xCimi3Q
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 LitmusChaos as it is easy to use, based on modern Chaos Engineering principles & community collaborated. It is 100% open source & a CNCF project.
LitmusChaos 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 (CRs) to define the chaos intent, as well as the steady state hypothesis.
At a high-level, Litmus comprises of:
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.
ChaosExperiment CRs are hosted on hub.litmuschaos.io. 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.
