本地仓库配置

安装本地仓库

docker run -itd -v /home/registry:/var/lib/registry -p 5000:5000 --restart=always --privileged=true --name registry registry:latest

配置私有仓库

vim /etc/docker/daemon.json
{
  "insecure-registries": ["192.168.64.6:5000"]
}
systemctl daemon-reload
systemctl restart docker

http://192.168.64.6:5000/v2/_catalog

开启docker 远程连接

vim /lib/systemd/system/docker.service

# 修改ExecStart为：
ExecStart=/usr/bin/dockerd -H fd:// --containerd=/run/containerd/containerd.sock -H 0.0.0.0:2375

配置项目

定义变量

在父级项目的pom->properties 添加如下配置 docker.host：docker安装的主机ip docker.registry.repository：上面搭建的本地仓库主机ip+端口号 docker.maven.plugin.version：插件版本

  <docker.host>http://192.168.64.2:2375</docker.host>
  <docker.registry.repository>192.168.64.2:5000</docker.registry.repository>
  <docker.maven.plugin.version>1.0.0</docker.maven.plugin.version>

添加编译插件

在父级项目的pom->build->pluginManagement->plugins添加如下配置

     <plugin>
                    <groupId>com.spotify</groupId>
                    <artifactId>docker-maven-plugin</artifactId>
                    <version>${docker.maven.plugin.version}</version>
                    <executions>
                        <execution>
                            <id>build-image</id>
                            <phase>package</phase>
                            <goals>
                                <goal>build</goal>
                                <goal>push</goal>
                            </goals>
                        </execution>
                    </executions>
                    <configuration>
                        <imageName>${docker.registry.repository}/${project.artifactId}:${project.version}</imageName>
                        <dockerHost>${docker.host}</dockerHost>
                        <baseImage>java:8</baseImage>
                        <entryPoint>["java", "-jar","-Dspring.profiles.active=prod","/${project.build.finalName}.jar"]
                        </entryPoint>
                        <resources>
                            <resource>
                                <targetPath>/</targetPath>
                                <directory>${project.build.directory}</directory>
                                <include>${project.build.finalName}.jar</include>
                            </resource>
                        </resources>
                    </configuration>
                </plugin>

添加打包方式到每个子模块中

将以下加入到每个子模块的pom中

    <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>
            </plugin>
        </plugins>
    </build>
