Spring boot 是現在web開發的首選框架， 這篇文章不是介紹Spring boot  特性的，介紹一種用Docker 容器簡單的部署Spring boot 應用的方式。

1： Spring boot 專案的構建我在這裡就不詳情的介紹了，不明白的童鞋可以百度下很簡單， 將Spring boot 專案使用Maven (我使用的是Maven) 打包如： docker-spring-boot-0.0.1-SNAPSHOT.jar 

2：構建Dockerfile 檔案 內容如下：

# from base image centos
FROM centos
MAINTAINER yueli
#install java
RUN yum -y install java
#inatall app 
#ADD <src> <dest> from appUrl to container destUrl
ADD tar /usr/project/
#start app
ENTRYPOINT ["java" ,"-jar","/usr/project/docker-spring-boot-0.0.1-SNAPSHOT.jar"]
 

3: 構建專案部署路徑

根據上文Dockerfile 檔案 ， 應用應放到 tar 目錄下 和 Dockerfile 同目錄下

[[email protected] docker]# ls
Dockerfile  tar

4：製作Docker 映象

[[email protected] docker]#docker build -t yueli/springboot .
