# PodDisruptor

The `PodDisruptor` class can inject different types of faults into the pods that match a selection criteria.

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

| [PodDisruptor.terminatePods()](/docs/k6/next/testing-guides/injecting-faults-with-xk6-disruptor/xk6-disruptor/poddisruptor/terminate-pods/)      | executes a [Pod Termination fault](/docs/k6/next/testing-guides/injecting-faults-with-xk6-disruptor/xk6-disruptor/faults/pod-termination/) in the target Pods |

## Example

This example:

- Creates a selector that matches all pods in the `default` namespace with the `run=nginx` label
- Injects a delay of 100ms and makes 10 percent of requests return an http response code `500`.

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

const selector = {
  namespace: 'default',
  select: {
    labels: {
      run: 'nginx',
    },
  },
};

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

export default function () {
  const disruptor = new PodDisruptor(selector);
  disruptor.injectHTTPFaults(fault, '30s');
}
