docker部署本地springboot项目

官网：https://spring.io/guides/gs/spring-boot-docker/

参考文档：https://my.oschina.net/AmosWang/blog/2088358

1.在项目的pom文件中添加：

            <plugin>
                <groupId>com.spotify</groupId>
                <artifactId>dockerfile-maven-plugin</artifactId>
                <version>1.3.6</version>
                <configuration>
                    <repository>${docker.image.prefix}/${project.artifactId} 
                    </repository>
                    <buildArgs>
                        <JAR_FILE>target/${project.build.finalName}.jar</JAR_FILE>
                    </buildArgs>
                </configuration>
            </plugin>



<properties>
        <java.version>1.8</java.version>
        <docker.image.prefix>pheony</docker.image.prefix>
</properties>

在项目目录下添加Dockerfile文件

FROM openjdk:8-jdk-alpine
VOLUME /tmp
ARG JAR_FILE
COPY ${JAR_FILE} app.jar
ENTRYPOINT ["java","-jar","/app.jar"]

2.项目打包

idea直接右边栏install即可或mvn install打包，生成文件在target目录下

3.本地安装docker 打开shell在项目目录下运行：mvn clean package docker:build  

  错误：No plugin found for prefix 'docker' in the current project and in the plugin groups.

            修改 maven 的配置文件 settings.xml

<pluginGroups>
    <pluginGroup>com.spotify</pluginGroup>
</pluginGroups>

错误：Must specify baseImage if dockerDirectory

          使用mvn clean package dockerfile:build

 4.本地镜像上传仓库，服务器上docker拉取
