5 springboot用的Dockerfile

FROM openjdk:8-jdk-alpine
# MAINTAINER gzz <gzz@163.com>
# VOLUME /tmp 
ADD gzz.jar gzz.jar 
ENTRYPOINT ["java","-jar","/gzz.jar"]

6 自己用的sh脚本

#!/bin/bash
cd ~
rm -rf gzz.jar
cd /root/83-spring-boot-docker
mvn clean
mvn package
mv /root/83-spring-boot-docker/target/spring-boot-docker-1.0.jar /root/gzz.jar
docker stop znk
docker rm znk
docker rmi znk
cd ~
docker build -t znk .
systemctl start firewalld
sleep 3s
docker run -d --name znk -p 8080:8080 znk
sleep 3s
systemctl stop firewalld
docker ps -a
docker images
docker logs -f -t --tail 100 znk
