This container image contains a tool to generates CPU load... duh :-)

When doing load testing on for example new clusters, I typical use a load generator to generate some "fake" load, however I couldn't find a simple container image for this job. So thats why I created this simple image to do the job.

Well running the container is not that hard if you have experience with Docker, running the CPU stress test tool itself is very straight forward. The switch option --cpu allows you to control how many cores will be used (in the example here below we use 4 cores). With the --timeout option it's possible to control how long the stress tool will run.

'''bash docker run -it --name cpustress --rm containerstack/cpustress --cpu 4 --timeout 30s --metrics-brief '''

To stop the CPU stress test container directly just run the following command.

'''bash docker stop cpustress '''
