# PowerfulSeal
[](https://travis-ci.com/powerfulseal/powerfulseal) [](https://pypi.python.org/pypi/powerfulseal)
**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](https://principlesofchaos.org).
Embrace the inevitable failure. Embrace The Seal.
## [Documentation](https://powerfulseal.github.io/powerfulseal)
Please refer to the [Powerfulseal documentation](https://powerfulseal.github.io/powerfulseal) to learn how to use it.
## Highlights
- works with `Kubernetes`, `OpenStack`, `AWS`, `Azure`, `GCP` and local machines
- `yaml` [policies](https://powerfulseal.github.io/powerfulseal/policies) describing complete chaos experiments
- `Prometheus` and `Datadog` metrics collection
- multiple [modes](https://powerfulseal.github.io/powerfulseal/modes) for differnt use cases
## Hello world!
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.
```yaml
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:
```sh
powerfulseal autonomous --policy-file ./policy.yaml
```
