categoryDescription: >
|

Pod-http-modify-body fault disrupts HTTP requests of kubernetes pods. This fault can modify the body of the response from the service targetted.
|
||||
- Causes modification of response body of the HTTP request.
|
||||
- The application pod should be healthy once chaos is stopped. Service-requests should be served despite chaos.
