使用Maven插件构建Docker镜像

1、本地私有仓库

# 先拉取镜像
docker pull registry:2
# 依赖的基础镜像需要先行下载
docker pull java:8

docker开启远程API

1、修改docker.service文件

vi /usr/lib/systemd/system/docker.service
# 需要修改的部分：
ExecStart=/usr/bin/dockerd -H fd:// --containerd=/run/containerd/containerd.sock
# 修改后:
ExecStart=/usr/bin/dockerd -H tcp://0.0.0.0:2375 -H unix://var/run/docker.sock

2、让Docker支持http上传镜像

vi /etc/docker/daemon.json 
{
  "registry-mirrors": ["https://dyv68vb0.mirror.aliyuncs.com"], # 阿里云镜像加速
	"insecure-registries": ["139.199.13.139:5000"] # 云服务器的外网ip
}
# 重启daemon进程
systemctl daemon-reload
# 重新启动Docker服务
systemctl restart docker

3、开启防火墙的Docker构建端口

firewall-cmd --zone=public --add-port=2375/tcp --permanent
firewall-cmd --reload

4、启动镜像仓库

# --restar=always docker重启，镜像仓库也会重启
docker run -d -p 5000:5000 --restart=always --name registry2 registry:2

docker-maven-plugin依赖

在应用的pom.xml文件中添加docker-maven-plugin的依赖

<plugin>
  <groupId>com.spotify</groupId>
  <artifactId>docker-maven-plugin</artifactId>
  <version>1.1.0</version>
  <executions>
    <execution>
      <id>build-image</id>
      <phase>package</phase>
      <goals>
        <goal>build</goal>
      </goals>
    </execution>
  </executions>
  <configuration>
    <imageName>mall-tiny/${project.artifactId}:${project.version}</imageName>
    <dockerHost>http://139.199.13.139:2375</dockerHost>
    <baseImage>java:8</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>
