在本地打包maven程序为docker镜像报错： Connect to localhost:2375 [localhost/127.0.0.1, localhost/0:0:0:0:0:0:0:1]

错误信息：

[ERROR] Failed to execute goal com.spotify:docker-maven-plugin:1.0.0:build (default-cli) on project farm: 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] failed: Connection refused: connect -> [Help 1]

我的错误原因是我没有打开本地的docker 2375端口

打开方式：右击右下角的小鲸鱼（我用的是docker for window），点击settings如下图

 将窗格打钩，即可。
