maven進行docker打包與推送

• docker.host 表示本地的docker主機,tcp走2375端口
• docker.registry 表示私服地址，本例使用harbor做為私服

<plugin>
    <groupId>io.fabric8</groupId>
    <artifactId>docker-maven-plugin</artifactId>
    <version>${docker.plugin.version}</version>
    <configuration>
        <!-- Docker本地主機 -->
        <dockerHost>${docker.host}</dockerHost>
        <!-- Docker 鏡像私服-->
        <registry>${docker.registry}</registry>
        <!-- 認證信息-->
        <authConfig>
            <push>
                <username>${docker.username}</username>
                <password>${docker.password}</password>
            </push>
        </authConfig>
        <images>
            <image>
                <name>${docker.registry}/${docker.namespace}/${project.name}:${project.version}</name>
                <build>
                    <dockerFile>${project.basedir}/Dockerfile</dockerFile>
                </build>
            </image>
        </images>
    </configuration>
</plugin>

• 本地docker主機需要開啟2375這個tcp端口

# 打開配置文件
vi /usr/lib/systemd/system/docker.service
# 添加2375端口
ExecStart=/usr/bin/dockerd -H tcp://0.0.0.0:2375 -H unix://var/run/docker.sock
# 重新加載配置文件并重啟服務
systemctl daemon-reload
systemctl restart docker

• 通過plugins的docker插件，進行build和push即可，需要注意本地docker主機與私服之間需要進行daemon.json的配置

{
  "registry-mirrors": ["//ay50ucm9.mirror.aliyuncs.com","//f2d6cb40.m.daocloud.io"],
  "insecure-registries":["//192.168.xx.xxx:8888"]
}

• maven推送

mvn clean package docker:stop docker:remove docker:build docker:run
# 或者直接打包推送：mvn docker:build docker:push

• 輸出

• 其它問題
  如果你的docker:build失敗，提示你的基礎鏡像不存在，我們可以把基礎鏡像添加到harbor中，模擬成為harbor中的鏡像就可以了
