# ServiceDisruptor

The `ServiceDisruptor` class can inject different types of faults into the pods that back a Kubernetes service.

To construct a `ServiceDisruptor`, use the [ServiceDisruptor() constructor](/docs/k6/latest/testing-guides/injecting-faults-with-xk6-disruptor/xk6-disruptor/servicedisruptor/constructor/).

## Example

The following example:

- Creates a disruptor for the `nginx` service
- Injects a delay of 100ms and a 10 percent of requests that return an http response code `500`.

```javascript
import { ServiceDisruptor } from 'k6/x/disruptor';

const fault = {
  averageDelay: '100ms',
  errorRate: 0.1,
  errorCode: 500,
};

export default function () {
  const disruptor = new ServiceDisruptor('nginx', 'default');
  disruptor.injectHTTPFaults(fault, '30s');
}
```

> Note
> 
> You can test this script by creating first a pod running nginx and exposing it as a service with the commands below, assuming you have [kubectl](https://kubernetes.io/docs/tasks/tools/#kubectl) installed in your environment:
> 
> Bash ![Copy code to clipboard](/media/images/icons/icon-copy-small-2.svg) Copy
> 
> ```bash
> > kubectl run nginx --image=nginx
> kubectl expose pod nginx --port 80

> 
> You can also use the [xk6-kubernetes](https://github.com/grafana/xk6-kubernetes) extension for creating these resources from your test script.
