Dockerfile制作完整镜像

1、创建dockerfile

touch Dockerfile

2、编写镜像创建的过程

vi Dockerfile

FROM monidev.midea.com/library/centos:7.3.1611
MAINTAINER wangzy25
#install java
#RUN yum -y install java
ADD ./jdk-7u79-linux-x64.tar.gz /root
#ADD ./ecf.platform.web-0.0.1-SNAPSHOT.jar /apps/svr/
#ADD ./start.sh /apps/svr/
##set environment variable
ENV JAVA_HOME /root/jdk1.7.0_79
ENV CLASSPATH .:$JAVA_HOME/lib:$JRE_HOME/lib
ENV PATH $JAVA_HOME/bin:$PATH
#set charset
ENV LANG "zh_CN.UTF-8"
#inatall app 
EXPOSE 80 443 8082
VOLUME ["/apps/logs/","/apps/svr/"]
#start app
CMD echo "start app ..."
#ENTRYPOINT java -jar /apps/svr/ecf.platform.web-0.0.1-SNAPSHOT.jar --server.port=8082 --spring.profiles.active=sit 
ENTRYPOINT /apps/svr/start.sh
CMD echo "started app success"

3、编写启动脚本

#!/bin/sh
source_path='.'
target_path='/apps/svr'
echo $target_path
cd /apps/svr
java -jar ecf.platform.web-0.0.1-SNAPSHOT.jar
#nohup java -jar ecf.platform.web-0.0.1-SNAPSHOT.jar --spring.profiles.active=sit > nohup.out & 2>&1 &
echo "$RUN_NAME started success."

4、以上是准备工作完毕，执行创建镜像命令：

docker build -t ecf/ecf.platform.web:v1 .

执行情况如下：

5、启动镜像

docker run -d  --name ecf.platform.sit  -p 8082:8082 -v /apps/projects/sit/ecf.platform.web:/apps/svr -v /apps/logs/sit:/apps/logs  70dc22557af3

6、查看启动状况

docker ps
