# 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](https://github.com/tstromberg/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](https://github.com/tstromberg/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.
|
|
