gcloud와 미니큐브 간에 kubectl 클러스터를 전환하는 방법

use AppleScript version "2.4" -- Yosemite (10.10) or later
use scripting additions

do shell script "/usr/local/bin/kubectl config current-context"
set curcontext to result

do shell script "/usr/local/bin/kubectl config get-contexts -o name"
set contexts to paragraphs of result

choose from list contexts with prompt "Select Context:" with title "K8s Context Selector" default items {curcontext}
set scriptArguments to item 1 of result

do shell script "/usr/local/bin/kubectl config use-context " & scriptArguments

display dialog "Switched to " & scriptArguments buttons {"ok"} default button 1

이 값을 CLI에서 전달할 필요는 없지만 ```values.yml``이라는 파일에 값을 저장할 수 있으며 환경마다 다른 파일을 가질 수 있습니다.

헬름 차트 표준으로 변환하는 데 약간의 작업이 필요하지만 그만한 가치가 있다.

$ kctx --help
