使用docker部署springboot应用
1、构造Dockerfile打包文件# from base image centos
FROM centos
#MAINTAINER lirenqing
#Java Version
#ENV JAVA_VERSION_MAJOR 7
#ENV JAVA_VERSION_MINOR 60
#ENV JAVA_PACKAGE jdk
#install java
RUN yum -y install java
#inatall app
ADD tar /usr/project/
#start app
ENTRYPOINT ["java" ,"-jar","/usr/project/docker-spring-boot-0.0.1-SNAPSHOT.jar"]
2、构建app部署文件路径
根据Dockerfile文件中定义的，app需要放置到tar目录下。dockerfile同目录下建立tar目录，并复制docker-spring-boot-0.0.1-SNAPSHOT.jar文件到tar目录。
3、制作docker镜像
➜docker$: docker build -t lirenqing/springboot .
Sending build context to Docker daemon 416.4 MB
Step 1 : FROM centos
---> 67591570dd29
Step 2 : ADD tar /usr/project/
---> Using cache
---> 6953cdf7e647
Step 3 : RUN yum -y install java
---> Using cache
---> 24307a233aff
Step 4 : ENTRYPOINT java -jar /usr/project/docker-spring-boot-0.0.1-SNAPSHOT.jar
---> Using cache
---> 1d32b755d223
Successfully built 1d32b755d223
4、运行docker image
➜docker$: docker run -p 8082:8081 lirenqing/springboot

当看到上面信息，证明已经运行成功了。可以直接访问localhost：8082即可访问构建的springboot应用了。
注：
本次构建由于网络原因，使用docker默认的镜像仓库下载经常出错，本次采用国内镜像网站下载。镜像代理设置可以访问：daodocker.io，需要注册一个帐号后有配置说明，参照配置说明配置即可。
