## 一.服务器安装docker ##

yum install docker

### 修改配置文件，打开2375端口 ###

[root@microservice ~]# vim /usr/lib/systemd/system/docker.service
    在ExecStart=/usr/bin/dockerd-current 后面加上-H tcp://0.0.0.0:2375 -H unix://var/run/docker.sock \
    重新加载配置文件和启动：
    systemctl daemon-reload
    systemctl start docker
    
    附：docker操作相关命令
    systemctl命令是系统服务管理器指令，它是 service 和 chkconfig 两个命令组合。
     启动docker：systemctl start docker
     停止docker：systemctl stop docker 
     重启docker：systemctl restart docker 
     查看docker状态：systemctl status docker   
     开机启动：systemctl enable docker 
    更详细的请参考：https://blog.csdn.net/linxiyimeng007/article/details/81080223

## 二、Idea安装docker支持插件及配置 ##

### 1.idea下载docker支持插件：Docker integration ###

（快捷键Crtl+shift+A   搜索Docker integration  ，然后启用，重启idea生效）

### 2.IDEA Docker插件配置 ###

File–>Settings–>Build,Execution,Deployment–>Docker–>进行如下配置：

tcp://服务器ip地址:2375

### **注意：** 只要下面提示Connection successfl 就表示连接成功了； ###

###  3.配置pom文件： ###

<build>
        <finalName>${project.artifactId}</finalName>
        <plugins>
            <plugin>
                <groupId>org.springframework.boot</groupId>
                <artifactId>spring-boot-maven-plugin</artifactId>
                <configuration>
                    <fork>true</fork>
                </configuration>
            </plugin>
            
            <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-surefire-plugin</artifactId>
                <configuration>
                    <skipTests>true</skipTests>
                </configuration>
            </plugin>
            
            <plugin>
                <groupId>com.spotify</groupId>
                <artifactId>docker-maven-plugin</artifactId>
                <version>1.0.0</version>
                
                <executions>
                    <execution>
                        <id>build-image</id>
                        
                        <phase>package</phase>
                        <goals>
                            <goal>build</goal>
                        </goals>
                    </execution>
                </executions>
                <configuration>
                    
                    <imageName>fred/${project.artifactId}</imageName>
                    
                    <imageTags>
                        <imageTag>latest</imageTag>
                    </imageTags>
                    
                    <dockerDirectory>src/main/docker</dockerDirectory>
                    
                    <dockerHost>http://服务器ip地址:2375</dockerHost>
                    
                    <resources>
                        <resource>
                            <targetPath>/</targetPath>
                            
                            <directory>${project.build.directory}</directory>
                            
                            <include>${project.build.finalName}.jar</include>
                        </resource>
                    </resources>
                </configuration>
            </plugin>
        </plugins>
    </build>

附项目目录结构：

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L0RyZWFtX3h1bg_size_16_color_FFFFFF_t_70 1][]

### 四、根目录下编写Dockerfile ###

# Dockerfile
    # 基于的镜像
    FROM openjdk:8-jdk-alpine
    
    VOLUME /opt/tmp
    
    ADD sg-business.jar app.jar
    
    # -Djava.security.egd=file:/dev/./urandom 可解决tomcat可能启动慢的问题
    # 具体可查看：https://www.cnblogs.com/mightyvincent/p/7685310.html
    ENTRYPOINT ["java","-Djava.security.egd=file:/dev/./urandom","-jar","/app.jar"]
    
    # 对外端口
    EXPOSE 8081

### 五、点击maven的package进行构建 ###

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L0RyZWFtX3h1bg_size_16_color_FFFFFF_t_70 2][]

构建成功的信息

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L0RyZWFtX3h1bg_size_16_color_FFFFFF_t_70 3][]

### 六、点击最下面的docker到docker界面，双击docker连上服务器docker会显示出服务器上的docker镜像，找到刚刚生成的镜像（图中2），点击创建容器 ###

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L0RyZWFtX3h1bg_size_16_color_FFFFFF_t_70 4][]

### 7.配置docker 容器对外暴露端口和项目接口端口，然后run启动容器 ###

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L0RyZWFtX3h1bg_size_16_color_FFFFFF_t_70 5][]

最后，设置好后，启动容器，启动成功后去阿里云查看是否启动成功
