构建docker镜像

使用jib:dockerBuild是在本地打包镜像，不push到远程，-X参数是显示debug信息
如果使用jib:build命令，则打包之后push到远程

mvn clean compile jib:dockerBuild -X

注意：
pom中用的是 registry.hub.docker.com/hengyunabc/arthas:latest 是 alibaba/arthas (阿里开源的一个Java诊断工具，便于线上调试)封装的docker镜像，如果不需要可以改成 registry.hub.docker.com/openjdk:8-jdk-alpine

使用arths：

$ docker run -d --init -p8563:8563 -p8080:8080 -e JAVA_OPTS='-Xms512m -Xmx512m' --name demo demo:latest
## 查看镜像发现所有的参数都加载进来了
$ docker inspect demo
## 下面是启动arthas，如果使用的是openjdk镜像请勿执行
$ docker exec -it demo /bin/sh
$ jid=$(jps | grep App | awk '{print $1}')
$ java -jar /opt/arthas/arthas-boot.jar --target-ip 0.0.0.0 ${jid}
