Ask HN: Stress Test Application for CPU/RAM/Disk

Hi there,

I want to check and then harden my Kubernetes cluster's stress tolerance by deploying some kind of stress generating application that would:

1) Try to hog as much CPU as possible

2) Try to allocate as much memory as possible

3) Try to saturate disk IO with a lot of operations

The question:

Do you know, can you advice any application that does some harmful chaotic activities, tries to misuse resources, e.g. hogs CPU and leaks memory like there's no tomorrow? Does not need to be Kubernetes specific, just need something that works on Linux ;)

I need this to test if resource limits we apply on our Kubernetes cluster work the way we expect them to work, before deploying production applications there.

Thanks!
