displayName: pod-http-latency
categoryDescription: |
Pod-http-latency contains chaos to disrupt http requests of kubernetes pods. This experiment can inject random http response delays on the app replica pods.
- Causes flaky access to application replica by injecting http response delay using toxiproxy.
- The application pod should be healthy once chaos is stopped. Service-requests should be served despite chaos.
