2 시나리오[ | ]

밑바닥부터 컨테이너 빌드

컨테이너 이미지를 빌드하기 위한 /root/Dockerfile 파일 생성
- 베이스 bash
- ping killercoda.com 실행
이미지를 pinger로 태그
my-ping이라는 이름으로 이미지 실행(컨테이너 생성)

레지스트리에 이미지 푸시

현재 pinger로 태그된 이미지를 local-registry:5000/pinger로 태그
로컬 레지스트리에 푸시

커스텀 태그로 레지스트리에 푸시

pinger로 태그된 이미지를 pinger:v1과 local-registry:5000/pinger:v1로 태그
로컬 레지스트리에 푸시
