Stress CPU
Attack
Generate CPU load for one or more cores. The resources on a host are shared between containers. Running a resource attack for a container is executed in the containers namespace, but affects the host's resources and all containers running on it.

Kubernetes Horizontal Pod Autoscaler Scales up Within Reasonable Time
Verify that your horizontal pod autoscaler scales up your Kubernetes deployment on increased CPU usage.
Motivation
Important deployments should be scaled up within a reasonable time for an elastic and resilient cloud infrastructure. Undetected high CPU spikes and long startup times are undesirable in these infrastructures.
Structure
First, we ensure that all pods are ready to serve traffic. Afterward, we inject high CPU usage into the pods' container and expect that within a reasonable amount of time, the horizontal pod auto scaler will increase the number of pods and become ready to handle incoming traffic.
