IntelliJ IDEA快速实现Docker镜像部署

IntelliJ IDEA快速实现Docker镜像部署

一、Docker开启远程访问

[root@izwz9eftauv7x69f5jvi96z docker]# vim /usr/lib/systemd/system/docker.service

1	`[root@izwz9eftauv7x69f5jvi96z docker]# vim /usr/lib/systemd/system/docker.service`

#修改ExecStart这行

ExecStart=/usr/bin/dockerd -H tcp://0.0.0.0:2375 -H unix:///var/run/docker.sock

#重新加载配置文件

1	`[root@izwz9eftauv7x69f5jvi96z docker]# systemctl daemon-reload`

#重启服务

1	`[root@izwz9eftauv7x69f5jvi96z docker]# systemctl restart docker.service`

#查看端口是否开启

1	`[root@izwz9eftauv7x69f5jvi96z docker]# netstat -nlpt`

#直接curl看是否生效

1	`[root@izwz9eftauv7x69f5jvi96z docker]# curl http://127.0.0.1:2375/info`

二、IntelliJ IDEA安装Docker插件

File–>Settings–>Plugins在搜索框中输入Docker，搜索并点击安装，安装完成后重启IDEA。

三、启用Docker

在File–> Settings–>Build,Execution,Deployment中找到Docker
新建一个Docker实例，连接成功后底部会显示Connection successful。

设置完成后，回到IDEA主界面，可以看到下面多出来一个Docker窗口或者在Services窗口中出现Docker。选中并连接Docker，连接上后显示Containers和Images就是我们现在Docker中已经有的容器和镜像。

四、使用Dockerfile构建镜像

1、修改pom文件，添加properties，添加plugin

<properties>
        <java.version>1.8</java.version>
        <docker.image.prefix>bozai</docker.image.prefix>
</properties> 
    <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>1.0.0</version>
                <configuration>
                    <imageName>${docker.image.prefix}/${project.artifactId}</imageName>
                    <dockerDirectory></dockerDirectory>
                    <resources>
                        <resource>
                            <targetPath>/</targetPath>
                            <directory>${project.build.directory}</directory>
                            <include>${project.build.finalName}.jar</include>
                        </resource>
                    </resources>
                </configuration>
            </plugin>
        </plugins>
    </build>

2、在项目的根目录下(和pom.xml同级)创建Dockerfile文件，内容如下：

FROM java:8
VOLUME /tmp
ADD target/*.jar app.jar
RUN /bin/cp /usr/share/zoneinfo/Asia/Shanghai /etc/localtime && echo 'Asia/Shanghai' >/etc/timezone #设置时区
EXPOSE 8089
ENTRYPOINT ["java","-Djava.security.egd=file:/dev/./urandom","-jar","/app.jar"]
