docker-打包发布脚本

思路：直接将jar包放到某个文件夹，通过脚本实现打包image，并发布

#目录下文件显示jar包、Dockerfile文件、打包启动脚本
[root@localhost mkpackge1]# ls
chinapopin-department-web-1.0-SNAPSHOT.jar  Dockerfile  qd.sh

#启动脚本内容
[root@localhost mkpackge1]# more qd.sh 
#!/bin/bash
dir=$(cd $(dirname $0);pwd)
i=${1-image_name}
#delete pod
docker rm -f $i
#delete image
docker rmi -f $i:latest
#makpage
cd $dir
docker build -t $i:latest .
#start pod
docker run --name $i --net=host -d $i:latest

#Dockerfile内容---注意需要修改jar的端口7002改成直接程序的
[root@localhost mkpackge1]# more Dockerfile 
FROM wukc/openjdk:8-jdk-alpine
COPY *.jar app.jar
EXPOSE 7002
ENTRYPOINT ["java","-jar","/app.jar"]

　　

启动方式sh qd.sh deploy_name

[root@localhost mkpackge1]# sh qd.sh department-web
