单点登录工程，后端的web服务，代码是用springboot写的，之前都是在测试环境用nohup java -jar直接运行的，现在要部署到docker服务器上

1.创建dockerfile文件

# Pull base image
FROM  java:8

MAINTAINER fengjian "ifengjian@qq.com"

VOLUME /tmp

# 添加
ADD sso-login-0.0.1-SNAPSHOT.jar app.jar
# Define default command.PROFILES 是可传递的变量
ENTRYPOINT ["sh","-c","java -jar app.jar --spring.profiles.active=$PROFILES "]
#设置时区
RUN /bin/cp /usr/share/zoneinfo/Asia/Shanghai /etc/localtime && echo 'Asia/Shanghai' >/etc/timezone

2.构建可运行的jar包

这一步简答，用maven工具直接package就好

    <build>
        <plugins>
            <plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>
            </plugin>
        </plugins>
    </build>

mvn package

3.制作镜像

将上边两步的jar包和dockfile文件上传到服务器上,如下

[root@localhost sso-login-web]# ls Dockerfile sso-login-0.0.1-SNAPSHOT.jar

然后创建镜像

[root@localhost sso-login-web]# docker build -t sso-login-web .

成功入上图所示,

[root@localhost sso-login-web]# docker images

4.运行并选择profile

[root@localhost sso-login-web]# docker run -d -p 8002:80 --name sso-login-web -e PROFILES="prod" sso-login-web:latest

8002是宿主机端口
80是程序里server.port的配置，这里是80端口
以上就是用docker打包springboot项目过程
