dockerHostUri didn't work

[steven-dai]

I referred to this address
my plugin info:

                        <plugin>
				<groupId>com.spotify</groupId>
				<artifactId>dockerfile-maven-plugin</artifactId>
				<version>1.4.13</version>
				<executions>
					<execution>
						<id>default</id>
						<goals>
							<goal>build</goal>
							<goal>push</goal>
						</goals>
					</execution>
				</executions>
				<configuration>
					<dockerHostUri>http://39.101.163.100:2375</dockerHostUri>
					<!-- dockerfile文件路径 -->
					<contextDirectory>./</contextDirectory>
					<!-- 镜像地址 -->
					<repository>${docker.registry}/demo</repository>
					<!-- 不指定tag默认为latest -->
					<tag>${project.version}</tag>
					<!-- 构建参数，可以传递给Dockerfile -->
					<buildArgs>
						<JAR_FILE>${project.build.finalName}.jar</JAR_FILE>
					</buildArgs>
				</configuration>
			</plugin>

when I exec DOCKER_HOST=http://39.101.163.100:2375 mvn clean package , it's ok!
when I exec mvn clean package ,it's error!
十月 29, 2020 5:08:51 下午 com.spotify.docker.client.shaded.org.apache.http.impl.execchain.RetryExec execute
信息: I/O exception (java.io.IOException) caught when processing request to {}->unix://localhost:80: No such file or directory

I want to add 'DOCKER_HOST' in my pom.xml，What should I do？Thanks

Did you get any answer for it? I was under impression that you cannot define DOCKER_HOST in POM.xml and used by env config of the docker client, but it would be cool if we could define it in pom.xml (LIke the spotify/docker-maven-plugin).

DOCKER_HOST=http://xxx.xxx.253.62:2375 mvn clean package dockerfile:build it's ok.
export DOCKER_HOST=tcp://xxx.xxx.253.62:2375
mvn clean package dockerfile:build but it's fail, not pass on image to docker host, why?
