#本文基于maven构建的spring boot项目，打包docker镜像需要安装docker
1、pom.xml添加docker打包插件
<plugin>
<groupId>com.spotify</groupId>
<artifactId>dockerfile-maven-plugin</artifactId>
<version>1.3.6</version>
<configuration>
<repository>${project.artifactId}</repository>
<buildArgs>
<JAR_FILE>target/${project.build.finalName}.jar</JAR_FILE>
</buildArgs>
</configuration>
</plugin>
2、在src同级目录下创建Dockerfile
FROM openjdk:8-jdk-alpine
VOLUME /tmp
ARG JAR_FILE
COPY ${JAR_FILE} app.jar
ENTRYPOINT ["java","-Djava.security.egd=file:/dev/./urandom","-jar","/app.jar"]
3、构建步骤
3.1 编译打包成jar包 mvn package -Dmaven.test.skip=true
3.2 将jar包打包成docker镜像：mvn dockerfile:build
4、运行命令：
docker run -d \
-p 8001:8001 \
-e "SPRING_PROFILES_ACTIVE=dev" \
--name auth \
-v /tmp/cloud-ac-service/auth/:/var/log/cloud-ac-service/auth \
auth:latest
4.1 命令说明
使用 -e "SPRING_PROFILES_ACTIVE=dev" 指定spring profile
使用 -v /tmp/cloud-ac-service/auth/:/var/log/cloud-ac-service/auth 挂载日志目录
