由于没有配置ip+2375端口，导致每次跑的时候，都是连接本地的，一直会报错
[ERROR] Failed to execute goal com.spotify:docker-maven-plugin:0.4.5:build (server) on project web-service: Exception caught: java.util.concurrent.ExecutionException: com.spotify.docker.client.shaded.javax.ws.rs.ProcessingException: org.apache.http.conn.HttpHostConnectException: Connect to localhost:2375 [localhost/127.0.0.1, localhost/0:0:0:0:0:0:0:1, localhost/fe80:0:0:0:0:0:0:1%1] failed: Connection refused -> [Help 1]
研究了几个小时，终于解决了。

加上 -H tcp://0.0.0.0:2375

重启docker,会发现2375起起来了

2种选择
要不配置环境变量：
要不在pom.xml添加
<dockerHost>http://192.168.180.105:2375</dockerHost>
