本文主要描述一下从零开始在CentOS7下，如何用docker部署springboot微服务

# docker的安装 #

安装一些必要的系统工具

sudo yum install -y yum-utils device-mapper-persistent-data lvm2

添加软件源信息：

sudo yum-config-manager --add-repo http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo

更新 yum 缓存：

sudo yum makecache fast

安装 Docker-ce：

sudo yum -y install docker-ce

启动 Docker 后台服务

sudo systemctl start docker

测试运行 hello-world

docker run hello-world

# Centos7中docker开启远程访问 #

#vi /usr/lib/systemd/system/docker.service
    [Service]
    ExecStart=ExecStart=/usr/bin/dockerd -H tcp://0.0.0.0:2375 -H unix://va/run/docker.sock 
    
    # systemctl daemon-reload
    # systemctl restart docker
    
    #firewall-cmd --zone=public --add-port=2375/tcp --permanent
    #systemctl restart firewalld.service

如果是ubuntu系统，则

vi /etc/default/docker
    DOCKER_OPTS=”-H unix:///var/run/docker.sock -H tcp://0.0.0.0:2375”
    
    service docker restart

# springboot项目的打包上传 #

项目所在windows主机上，配置环境变量，这里的\{docker\_ip\}就是docker所在的linux机器的\{docker\_ip\}

DOCKER_HOST=tcp://{docker_ip}:2375

配置maven的pom.xml

<build>
    		<plugins>
     			<plugin>
    				<groupId>org.springframework.boot</groupId>
    				<artifactId>spring-boot-maven-plugin</artifactId>
    			</plugin>
    			
                
                <plugin>
                    <groupId>com.spotify</groupId>
                    <artifactId>docker-maven-plugin</artifactId>
                    <version>0.4.12</version>
                    <configuration>
                        
                        
                        <imageName>fhbean/dockertest</imageName>
                        <baseImage>java</baseImage>
                        <entryPoint>["java", "-jar", "/${project.build.finalName}.jar"]</entryPoint>
                        <resources>
                            <resource>
                                <targetPath>/</targetPath>
                                <directory>${project.build.directory}</directory>
                                <include>${project.build.finalName}.jar</include>
                            </resource>
                        </resources>
                    </configuration>
                </plugin>
     		</plugins>
    	</build>

maven打包，或在run configuration中goal增加clean package docker:build

mvn clean package docker:build

# docker启动容器 #

[root@s01 ~]# docker run -d -p 8080:8080 -t fhbean/dockertest

这时就可以在浏览器访问了。
