Springboot应用打包
使用
spring-boot-maven-plugin插件，打包为可执行jar<build> <plugins> <plugin> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-maven-plugin</artifactId> </plugin> </plugins> </build>
新建Dockerfile文件
文件可以直接放在工程根目录下（和target同级目录）
FROM openjdk:8u212-jre LABEL author=Jason email=qianhao_cs@163.com COPY target/SpringbootDemo-1.0-SNAPSHOT.jar /SpringbootDemo-1.0-SNAPSHOT.jar ENTRYPOINT ["java", "-jar", "/SpringbootDemo-1.0-SNAPSHOT.jar"]
构建镜像
可以使用IDEA的docker插件直接构建
也可以使用命令进行构建
