kubestress

Kubestress is a tool designed for testing auto-scaling of Kubernetes. It can generate a fixed amount of workload (currently only CPU) to simulate a certain amount of stress from external sources. The goal of kubestress is to test the scaling behavior for Kubernetes cluster without having to use stress testing tool like Locust or JMeter that generate traffic externally.

Environmental Variables

The following ENVs are required for running the stress testing.

ENV Name	Description
DEPLOYMENT_NAME	Name of the deployment. This will be automatically maintained by the Helm chart.
TOTAL_CPU_LOAD	Total desired CPU load for the entire deployment. The unit is milli cores.
PER_POD_PROCESS	Number of stress-ng processes per pod. By default, there is only 1 process per pod.
PER_POD_CPU_LIMIT	CPU limit of each pod. Same value as spec.template.spec.containers[0].resources.limits.cpu.
TEST_PERIOD_SECOND	Length of each run of stress-ng. The unit is seconds.
