spec:
displayName: pod-memory-hog
categoryDescription: |
Pod-Memory-Hog contains chaos to consume memory resouces of specified containers in Kubernetes pods.
- Causes memory resource consumption on specified application containers using cgroups and litmus nsutil that consume memory resources of the given target containers.
- It Can test the application's resilience to potential slowness/unavailability of some replicas due to high memory load
- The application pod should be healthy once chaos is stopped. Expectation is that service-requests should be served despite chaos.
