IDEA 使用Docker构建镜像

安装Docker#

Windows#

1、下载并安装Docker Desktop
2、勾选配置

3、配置参数

{
  "builder": {
    "gc": {
      "defaultKeepStorage": "20GB",
      "enabled": true
    }
  },
  "experimental": false,
  "host": [
    "0.0.0.0:2375"
  ],
  "insecure-registries": [
    "127.0.0.1:8888"//接不受信任的镜像仓库地址
  ],
  "registry-mirrors": [
    "https://registry.docker-cn.com",
    "http://hub-mirror.c.163.com",
    "https://docker.mirrors.ustc.edu.cn",
    "https://cr.console.aliyun.com",
    "https://mirror.ccs.tencentyun.com"
  ]
}

Linux#

1、安装docker
2、开启tcp端口访问，执行命令sudo vim /lib/systemd/system/docker.service修改配置文件

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

3、重新加载配置systemctl daemon-reload
4、重启dockersystemctl restart docker

IDEA操作#

1、IDEA安装docker插件并添加docker

2、在工程得pom.xml添加配置

<build>
<!--         jar包名称-->
    <finalName>food-service</finalName>
    <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>0.4.13</version>
            <executions>
                <execution>
                    <id>build-image</id>
                    <phase>package</phase>
                    <goals>
                        <goal>build</goal>
                    </goals>
                </execution>
            </executions>

            <configuration>
                <!-- 打包镜像名称 -->
                <imageName></imageName>
                <!-- 本地docker地址 -->
                <dockerHost>http://localhost:2375</dockerHost>
                <!-- Dockerfile路径 -->
                <dockerDirectory>${project.basedir}</dockerDirectory>
                <resources>
                    <resource>
                        <targetPath>/</targetPath>
                        <directory>${project.build.directory}</directory>
                        <include>${project.build.finalName}.jar</include>
                    </resource>
                </resources>
            </configuration>
        </plugin>
    </plugins>
</build>

3、添加dockerfile文件并配置

FROM 基础包
ADD target/服务名.jar /app.jar
ENV TZ Asia/Shanghai
ENTRYPOINT ["java","-jar","/app.jar"]

4、maven打包
