deploy script - (aws) cloudfront invalidation (cdn purge)

 

 

 

 

■ 설명

AWS 환경에서 cloudfront를 이용하여 CDN 구성을 할 경우 invalidation (무효화, purge) 를 코드로 진행하는 방법입니다.

참고로 invalidation은 최대 10분 이상도 소요될 수 있습니다. (같은 파일을 진행해도 랜덤하게 시간이 달라집니다.)

 

 

■ 로직

1. cloudfront api를 이용하여 invalidation 실행

2. processing을 체크하고, 완료되면 done 출력

 

 

■ 코드

#환경에 맞게 수정
- invalidation_name
- env

#!/bin/bash

export INVALIDATION_ID=$1
export INVALIDATION_PATH=$2
export INVALIDATION_NAME=cloudfront-mkdir-chandler

export ENV=dev
