litmus: err: Unable to Get the chaosengine

err: Unable to Get the chaosengine

My environment is pretty simple. I have an azure k8s cluster, and followed this guide https://istio.io/latest/docs/setup/getting-started/ to setup my environment. In other words, the namespace is enabled with istio injection.

Litmus is setup, and I was trying to run pod-delete experiment. Chaos runner pod is created, but I saw errors though. “pod-delete” pod is also created, but the target pod was not deleted. When I was looking at logs by k logs -f pod-delete-4y48y4-ql64c -c pod-delete-4y48y4, I saw error

Unable to initialise probes details from chaosengine, err: Unable to Get the chaosengine, err: Get \"https://10.0.0.1:443/apis/litmuschaos.io/v1alpha1/namespaces/default/chaosengines/bookinfo-chaos\": dial tcp 10.0.0.1:443: connect: connection refused

This is my engine yaml, https://drive.google.com/file/d/1HAaMLamHS3BZP6SDNtD_-YO1pdl46vnh/view?usp=sharing

Litmus version is 1.9.0

Ok we need to add the annotation sidecar.istio.io/inject: "false" in the chaos-runner, experiment pod & helpers to prevent sidecar injection & in turn avoid this issue in accessing kube-apiserver. Litmus supports adding custom annotations to the chaos pods via an instrumentation in the chaosengine. Please refer the example below:

apiVersion: litmuschaos.io/v1alpha1
kind: ChaosEngine
metadata:
  name: nginx-chaos
  namespace: default
spec:
  appinfo:
    appns: 'default'
    applabel: 'app=nginx'
    appkind: 'deployment'
  annotationCheck: 'true'
  engineState: 'active'
  chaosServiceAccount: pod-delete-sa
  monitoring: false
  components:
    runner: 
      runnerannotation:
        sidecar.istio.io/inject: "false"
  jobCleanUpPolicy: 'delete'
  experiments:
    - name: pod-delete
      spec:
        components:
          experimentannotation: 
            sidecar.istio.io/inject: "false"
          env:
            - name: TOTAL_CHAOS_DURATION
              value: '30'
            - name: CHAOS_INTERVAL
              value: '10'
            - name: FORCE
              value: 'false'
