Policies

Just to give you a taste, here’s an example policy. It will kill a single pod, and then check that the service continues responding to HTTP probes, to verify its resiliency to one of its pods going down.

scenarios:
- name: Kill one pod in my namespace, make sure the service responds
  steps:
  # kill a pod from `myapp` namespace
  - podAction:
      matches:
        - namespace: myapp
      filters:
        - randomSample:
            size: 1
      actions:
        - kill:
            probability: 0.75
  # check my service continues working
  - probeHTTP:
      target:
        service:
          name: my-service
          namespace: myapp
      endpoint: /healthz
