PowerfulSeal injects failure into your Kubernetes clusters, so that you can detect problems as early as possible. It allows for writing scenarios describing complete chaos experiments.
Please refer to the Powerfulseal documentation to learn how to use it.
- works with
GCPand local machines
yamlpolicies describing complete chaos experiments
- multiple modes for differnt use cases
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
Assuming that's in
policy.yml, you can run it like this:
powerfulseal autonomous --policy-file ./policy.yaml
