添加maven docker插件

<plugin>
                <groupId>com.spotify</groupId>
                <artifactId>docker-maven-plugin</artifactId>
                <!--<version>0.2.3</version>-->
                <version>0.4.11</version>
                <configuration>
                    <imageName>${docker.image.prefix}/${project.artifactId}</imageName>
                    <dockerDirectory>src/main/docker</dockerDirectory>
                    <resources>
                        <resource>
                            <targetPath>/</targetPath>
                            <directory>${project.build.directory}</directory>
                            <include>${project.build.finalName}.jar</include>
                        </resource>
                    </resources>
                </configuration>
            </plugin>

制作镜像

$ docker build -t amyservice .
-t代表要构建的镜像的tag
.代表当前目录，也就是Dockerfile所在的目录

启动

$ docker run -d -p 8086:8086 --name amy amyservice:latest

进入容器,alpine为精简版本linux 没有安装bash shell，需要用ash

$ docker exec -it  ID ash
