| # 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. | ||
| If you update the benchmark results to [our website](https://minikube.sigs.k8s.io/docs/benchmarks/), please commit this change. | ||
|
|
||
| ``` | ||
| git status | ||
| git add <Changed png file> | ||
