도커 | 3강. dockerfile (mac 맥 m1)

https://heytech.tistory.com/33

[Mac/Linux] 터미널에서 파일 생성/편집/저장 방법

 

도커파일 실습1 - 자바를 설치하고 자바 파일을 생성해서 실행해보기

준비사항

• course/docker/first 예제폴더를 생성하고 이동해주세요.
• window에서 실습하고 있지만, 리눅스 환경이라고 생각하고 사용하는 편이 좋습니다.

docker 경로로 이동

 

1. 메모장 만들기

cat > 파일명.확장자명

-메모장 작성 예시

cat > memo.txt 

cat > Hello.java

2. 내용 작성

public class Hello { public static void main(String[] args) { System.out.println("hello world"); } }

ctrl + z 누르면 나가짐

 

3. 자바이미지 찾기

docker search openjdk

4. 도커파일생성

cat > dockerfile

5. 도커파일작성

FROM adoptopenjdk/openjdk11

COPY Hello.java /

RUN javac Hello.java

ENTRYPOINT ["java", "Hello"]

 

6. 도커파일을 빌드하여 이미지로 만들기

docker build -t <이미지명>:<태그> <빌드할도커파일위치>
docker build -t hellojava:latest .

. 은 현재 위치

7. 컨테이너 실행

docker run <옵션> <이미지:태그>
docker run --name first hellojava:latest

 

 

컨테이너 안에 살펴보기

 

또 에러뜸..미치겠다.
