1、基于ubuntu 的镜像($app 此处为占位符号，替换为自己的spring boot 项目的jar)

FROM ubuntu:16.04

MAINTAINER modian(744955753@qq.com)

ADD jdk-8u151-linux-x64.tar.gz /usr/local/jdk8

ENV JAVA_HOME /usr/local/jdk8/jdk1.8.0_151

ENV JRE_HOME $JAVA_HOME/jre

ENV CLASSPATH :$JAVA_HOME/lib:$JRE_HOME/lib

ENV PATH $PATH:$JAVA_HOME/bin

ARG appADD $app app.jar

ENTRYPOINT ["java","-Djava.security.egd=file:/dev/./urandom","-jar","/app.jar"]

2、基于已有的java8镜像进行spring boot镜像制作 （pbplatform-example-1.0.jar 占位符）

FROM java:8
VOLUME /tmp
ARG JAR_FILE
ADD pbplatform-example-1.0.jar app.jar
RUN bash -c 'touch /app.jar'
EXPOSE 8800
ENTRYPOINT ["java","-Djava.security.egd=file:/dev/./urandom","-jar","-Denv=DEV","/app.jar"]
