0.Pre-requirement

krew installed on your system and make permanent export to avoid your bothering.

Installing · Krewkrew.sigs.k8s.io

If you have any kind of issue you would be destroy it. uninstall is best solution most of times.

Uninstalling Krew · Krewkrew.sigs.k8s.io

Note: This document based on this document. So I recommend to read both.

Using Custom Plugin Indexes · Krewkrew.sigs.k8s.io

1.Build your own plugin files

1-1.Executable file

Here is SAMPLE file. it has this code as a bash.

<snipped> <snipped> 

main() {
  # avoid chaos history 
  unset HISTFILE
  
  # create ctxon working directory & kubectxon as well 
  set_env

  # backup history forcely 
  \cp -rf $historyPATH $HOME/.ctxon/.backup_history	

  pass_kubectl
  ARGS=${@:1}

  if [[ "$#" -eq 0 ]]; then
    ARG1="default" 
    toggle_ctxon
    exit 0
  elif [[ "$1" == "-h" || "$1" == "--help" ]]; then
    usage
    exit 0
  elif [[ "$1" == "uninstall" ]]; then
    unset_env
    exit 0
  elif (( $1 >= 30 && $1 <= 37 || $1 >=40 && $1 <=47 )); then
    ARG1="$1"	  
    toggle_ctxon
    exit 0 
  else
    echo "$ARGS Option Not Supported"	 
    exit 1  
  fi

  # history recovery and up all 
  echo $historyPATH
  mv $HOME/.ctxon/.backup_history $historyPATH
  history -c; history -r $historyPATH
  set HISTFILE
}

main "$@"

1-2.LICENSE

Here is SAMPLE file. it is MIT.

1-3.Achieving files

Both tar.gz or zip are okay. so you could use as your preference.

$ tar cvfz kubectxon_v0.0.3_linux_arm64.tar.gz kubectxon LICENSE

1-4.Upload achieved file your repo's releases

1-5.make manifest file

Here is SAMPLE ctxon.yaml file. it needs to create in LOCAL first

1-6.Check Validation

It can check automatically (especially sha256), so you could verify and modify as this guideline.

Testing plugin installation locally · Krewkrew.sigs.k8s.io

Here is some error on sha256, so I changed as this guideline. or you could make it before showing this error. online-sha256 link.

$ kubectl krew install --manifest=ctxon.yaml --archive=kubectxon_v0.0.3_linux_arm64.tar.gz

2.Publish your files

2-1.Create REPO like this tree structure.

GitHub - sysnet4admin/custom-index: custom-index for kubernetes's krewGitHub

i.e. manifest files should locate in plugins folder from main.

plugins folder have actual manifests. so upload your manifest in plugins folder

it is same methodology from default (krew-index)

2-2.Check your upload files to your system :)

Here is the procedure of installation. it should work if you have no issue until here.

custom-index/plugins at master · sysnet4admin/custom-indexGitHub

See ya!!!
