Investigate Kubemark

[chaitanyaenr]

A cluster with hundreds/thousands of nodes is needed to test and see how Cerberus runs at scale. In discussion with @smalleni about project Sahasra which simulates the compute nodes to stress the OpenStack control plane, we were wondering if doing the same will help us with testing Cerberus. We had an issue open about it to help with testing the control plane/cluster maximums without having to set up a large scale cluster but Kubemark being specific to Kubernetes might not be the right fit.

We need to investigate Kubemark to see if will suffice our need for testing Cerberus at scale by simulating worker nodes to stress the control plane instead of using real hardware: https://github.com/kubernetes/kubernetes/tree/a8128804abbc311328b146c007df2cac09ba7fdf/test/kubemark/pre-existing.

NOTE: This might be an overkill for solving a simple problem :-)
