build: address all lint issues by v2 (#20804) 
* fix QF1011: could omit type *os.File from declaration; it will be inferred from the right-hand side

* fix QF1012: Use fmt.Fprintf(x, ...) instead of x.Write(fmt.Sprintf(...))

* fix QF1001: could apply De Morgan's law

* fix QF1003: could use tagged switch

* fix weakCond: suspicious ; nil check may not be enough, check for len (gocritic)

* fix docStub: silencing go lint doc-comment warnings is unadvised

* fix builtinShadow: shadowing of predeclared identifier: error

* fix importShadow: shadow of imported package

* fix nestingReduce: invert if cond, replace body with , move old body after the statement

* useless-break: useless break in case clause (revive)

* Clear the redundant content in golangci.yaml file

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.
