소개

Jib이란?

Maven, Gradle의 플러그인으로 정의하고 Docker 데몬을 사용하지 않고 Docker 이미지를 만들고 레지스트리에 푸시 할 수있는 도구

빠진 곳도 쓰면서 순서를 설명한다
빠는 1 : 프록시
빠는 2 : 인증

환경

OS : Windows
IDE : eclipse
build : Maven
jib-maven-plugin : 1.0.2

전제

dockerhub 계정이 있음
Repository를 만들어 두는 것 (이번에는 test라는 이름으로 갔다)

적당한 Maven 프로젝트를 떨어뜨린다

뭐든지 좋아. 자신은 다음을 떨어뜨렸다.
