도커 이미지 일괄 태깅·푸시 및 정리 자동화 Bash 스크립트

💡 핵심 요약 (Executive Summary)

본 가이드는 bash docker control image.sh 핵심 가이드 및 실전 아키텍처의 핵심 개념, 실전 구성 명령어 및 아키텍처 베스트 프랙티스를 다룹니다. 클라우드 네이티브 및 인프라 엔지니어링 실무에 즉시 활용 가능하도록 체계적으로 정리했습니다.

Image pull&pusher
  1. K8s이미지를 도커 리포지토리에서 pull
  2. tag 지정
  3. REPO (지정 harbor)에 push
Reference & Guidelines (NOTE)

인터넷이 가능하며 docker가 설치된 환경이어야 한다.

Archi 확인
bash
#!/bin/bash
IMAGES=$(sudo docker images | sed '1d' | awk '{print $1 ":" $2}')

for IMAGE in $IMAGES
do
  sudo docker image inspect $IMAGE | jq ".[0].Architecture"
done
Tagging
Reference & Guidelines (NOTE)

docker hub에서 다운로드 받은 이미지에 특정 repository를 태깅

bash
#!/bin/bash
REPO=""
IMAGES=$(sudo docker images | sed '1d' | awk '{print $1 ":" $2}')

for IMAGE in $IMAGES
do
  sudo docker tag $IMAGE ${REPO}/${IMAGE}
done
Reference & Guidelines (NOTE)

특정 asis repository를 특정 tobe repository로 태깅
