What is these scripts

These scripts are for the benchmark of cpu usage, minikube vs kind vs k3d.

• benchmark_local_k8s.sh: take benchmark for cpu usage. This will take long to take place
• update_summary.sh: create one summary csv file of each drivers and products
• chart.go: create bar chart graph as a png file

In benchmark_local_k8s.sh, we compare minikube drivers(hyperkit, virtualbox, docker with auto-pause addon) and kind, k3d, Docker for Mac Kubernetes in case of macOS.
In benchmark_local_k8s.sh, we compare minikube drivers(kvm2, virtualbox, docker with auto-pause addon) and kind, k3d in case of Linux.
benchmark_local_k8s.sh take these steps to measure auto-pause vs. non auto-pause.

1. start each local kubernetes tool
2. deploy sample application(nginx deployment) to each tool
3. wait 1 minute without anything
4. measure No.3 idle CPU usage with cstat
5. if tool is minikube, enable auto-pause addon which pause control plane
6. if tool is minikube, wait 1 minute so that control plane will become Paused status(It takes 1 minute to become Pause status from Stopped status)
7. if tool is minikube, verify if minikube control plane is paused
8. if tool is minikube, wait 3 minute without anything
9. if tool is minikube, measure No.8 idle CPU usage with cstat

No.1-4: Initial start CPU usage with sample(nginx) deployment
No.5-9: Auto Paused CPU usage with sample(nginx) deployment

How to use these scripts

cd <Top of minikube directory>
make cpu-benchmark-benchmark-autopause

After running make cpu-benchmark-autopause, the png file of the bar chart graph will be generated.
If you update the benchmark results to our website, please commit this change.
