1. JDK 17 베이스 이미지로 컨테이너 띄워보기
1) Dockerfile 생성
Docker Hub - openjdk : https://hub.docker.com/_/openjdk
openjdk - Official Image | Docker Hub
Docker Official Images are a curated set of Docker open source and drop-in solution repositories. Why Official Images? These images have clear documentation, promote best practices, and are designed for the most common use cases.

# JDK 17
# FROM openjdk:17-jdk # Deprecated 됨
FROM eclipse-temurin:17-jdk
2) Dockerfile 기반으로 이미지 생성
# docker build -t 이미지명:태그명 Dockerfile 존재하는 디렉토리 경로 : Dockerfile 기반으로 이미지 생성
태그명 생략시 latest 로 설정
- Windows PowerShell
# docker build -t sample .
# docker build -t sample:1.0 .
