编写dockerfile实现项目自动运行

我们打包项目，因为是集群，所以两个项目版本分别搞成v1和v2 端口分别是8888和9999

项目1：

FROM centos

MAINTAINER caofeng<caofeng2012@126.com>

LABEL name="Java1234 Jre Image" \

    build-date="20200114"

ADD server-jre-8u151-linux-x64.tar.gz /home/

ADD sessionshare2-v1.jar /home/

ENV WORKPATH /home/

WORKDIR $WORKPATH

ENV JAVA_HOME /home/jdk1.8.0_151

ENV CLASSPATH $JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar

ENV PATH $PATH:$JAVA_HOME/bin

EXPOSE 8888

CMD java -jar /home/sessionshare2-v1.jar

项目2：

FROM centos

MAINTAINER caofeng<caofeng2012@126.com>

LABEL name="Java1234 Jre Image" \

    build-date="20200114"

ADD server-jre-8u151-linux-x64.tar.gz /home/

ADD sessionshare2-v2.jar /home/

ENV WORKPATH /home/

WORKDIR $WORKPATH

ENV JAVA_HOME /home/jdk1.8.0_151

ENV CLASSPATH $JAVA_HOME/lib/dt.jar:$JAVA_HOME/lib/tools.jar

ENV PATH $PATH:$JAVA_HOME/bin

EXPOSE 9999

CMD java -jar /home/sessionshare2-v2.jar

构建镜像

docker build -f myJreDockerFile -t java1234/myjre:1.7 .

docker build -f myJreDockerFile2 -t java1234/myjre:2.1 .

并且启动镜像

docker run -itd -p 8888:8888 eb587d987876

docker run -itd -p 9999:9999 45b7242944ca
