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.
