This is a container image and wrapper script for stress: https://linux.die.net/man/1/stress This is for easy execution of stress without installing the package (e.g. on a distro where the package is not in the repos). It also includes a script which auto-identifies CPU count and free memory, then hogs it. You can obviously bypass it if you don't like how it works. This has some configuration options for level of the test and whether you want it to apply I/O load.
