idea Maven 插件 docker-maven-plugin 打包docker镜像上传到远程仓库

参考资料 https://my.oschina.net/u/3764794/blog/2995648

原理：

docker-maven-plugin 调用一个 docker 的api,进行打包镜像，tag标签，push到远程仓库。

远程仓库的密码,在本地maven 的setting.xml里配置一个server ，idea根据id可以获取到远程仓库的账号，密码

一、docker主机开启docker 远程访问API

Ubuntu：

vi /lib/systemd/system/docker.service

Centos7

vi /usr/lib/systemd/system/docker.service 

找到ExecStart

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

修改完后 重置重启

systemctl daemon-reload
systemctl restart docker

防火墙开放端口:2375

验证

http://ip:2375/images/json  或 curl http:/ip:2375/info

二、在docker主机配置远程仓库地址，以便非https 也能访问

vi  /etc/docker/daemon.json

{
"registry-mirrors":  [
"https://dockerhub.azk8s.cn",
"https://reg-mirror.qiniu.com"
],
    "insecure-registries": ["registry1的IP地址:端口号","registry2的IP地址:端口号"]
}

修改完后 重置重启

systemctl daemon-reload
systemctl restart docker

三、maven 配置 远程仓库的账号密码

编辑 maven settings.xml文件

 <server>  
        <id>local_docker</id>  
         <username>lulu</username>
        <password>123456</password>
 </server> 

四、pom 配置

<properties>
    <project.name>bluetoothled</project.name>
<!-- 私有仓库配置，需要settings.xml文件配合serverId对应的仓库服务 账号密码 -->
    <docker.serverId>local_docker</docker.serverId>
    <docker.registry>192.168.182.100:5000</docker.registry>
     <docker.host>http://192.168.182.100:2375</docker.host>
</properties>

            </plugin>

        </plugins>
    </build>

docker-maven-plugin 详细说明请参考https://my.oschina.net/u/3764794/blog/2995648

五、在idea中命令控制台中使用

创建镜像

mvn clean package docker:build

推送镜像到Registry

mvn clean package docker:build -DpushImage

推送指定tag的镜像到Registry

mvn clean package docker:build -DpushImageTag

执行 build、tag、push 操作

mvn deploy

如果想跳过 docker 某个过程时，只需要：
-DskipDockerBuild 跳过 build 镜像
-DskipDockerTag 跳过 tag 镜像
-DskipDockerPush 跳过 push 镜像
-DskipDocker 跳过整个阶段
