New Features and Enhancements

• Features a revamped chaos charthub with a more resilient design and improved user experience

• Introduces ability (github workflows) to trigger individual/multiple e2e tests or complete e2e test-suite for litmus PRs via GitHub comments

• Adds a new repo litmuschaos/litmus-demo to provide a fully packaged demo environment to run chaos under 10 min

• Adds node service kill chaos chaos libraries (& kubelet kill chaos experiment on specified nodes)

• Improves the pod cpu hog experiment by adding go chaoslib to support containerd/crio runtime

• Introduces chaoslib pattern to choose blast radius / percentage (target) pods and abort chaos on target containers

• Improves the chaos-scheduler controller to halt/resume chaos

• Enhances the chaos-schedule CR schema to provide dedicated attributes for the schedule modes (now, once, repeat) over mutually-exclusive fields with enhanced OpenAPI schema validation

• Introduces ImagePullPolicy as a chaosexperiment CR attribute (.spec.definition.imagePullPolicy) to support usecases where the experiments are needed to be run with locally built images, as with PR-triggered e2e

• Enhances the container-kill experiment to repeat the chaos per an interval over a total duration with support for containerd/crio runtime.

• Adds go-based helper pods for pod-delete and container-kill chaos libraries

• Improves the litmus-go scaffold tool to use lighter base images & improved default events

• Improves the validating webhook-based admission controller to call out missed annotations on target applications

• Improves unit-test coverage for chaos-operator

• Enhances the getting started (chaosengine construction) & troubleshooting docs (uninstallation steps)

Major Bug Fixes

• Fixes the missing/clustered event generation on litmus-go chaos experiment

• Fixes operator behavior of triggering chaos disregarding annotation status on the target application

• Fixes the cluster level running experiment count metric from chaos-exporter

• Adds concurrent updation of the event counter for each iteration of chaos injection

• Fixes chaos experiment failures (securitycontext additions) on OpenShift 4.3

Installation

kubectl apply -f https://litmuschaos.github.io/litmus/litmus-operator-v1.5.0.yaml

Verify your installation

• Verify if the chaos operator is running
  kubectl get pods -n litmus
