LitmusChaos Jenkins Template

• It is a CI template to run litmus experiment in jenkins pipelines stage.

• This template provides a way to perform a chaos experiments on the Kubernetes environment. It contains Litmus Chaos experiments to run the chaos and find a weakness in the system.

Pre-requisites

Notice The jnlp container in Jenkinsfile is the default execution container. you can find the complete more details here.

Execution Details

• The pod-template used here is using litmuschaos/chaos-ci-lib image from chaos-ci-lib repository which is a central point for all chaos execution.
• We can tune the ENVs in the template for set the certain paramerters like Application Details ( like name,namespace and kind), Chaos Details (like Chaos Duration, Chaos Interval etc ...)

Create new template

• To create and use a new template we just need to update the EXPERIMENT_NAME with the experiment name supported in chaos-ci-lib. For Example to use container kill we can use:

metadata:
  name: container-kill
  labels:
    experiment: container-kill
spec:
  serviceAccountName: litmus-jenkins-sa
  containers:
  - name: jnlp
    image: litmuschaos/chaos-ci-lib:v0.4.0
    imagePullPolicy: Always
    tty: true
    command: ["/bin/bash"]
    args:
    - -c 
    - ./experiment_entrypoint.sh
    env:
    - name: INSTALL_LITMUS
      value: "true"
    - name: EXPERIMENT_NAME
      value: "container-kill"
    - name: UNINSTALL_LITMUS
      value: "true
