Block I/O Demo

This demo creates a virtual machine for a single-node Kubernetes* cluster where container runtime features are extended by cri-resmgr.

In this setup, cri-resmgr is configured with block I/O parameters that throttle I/O bandwith of a container that constantly scans system file checksums.

Prerequisites

Install:

• docker

• govm

Run the demo

./run.sh play

The demo does not delete the virtual machine so that you can experiment with it. You can login to the virtual machine:

$ govm ssh crirm-demo-blockio

Clean up - and run the demo from scratch

In order to run the demo from scratch again, delete the virtual machine:

$ govm delete crirm-demo-blockio
