我开始使用com.spotify.docker-maven-plugin，但 GitHub 上的 wiki 说要切换到com.spotify.dockerfile-maven-plugin。然而，在第一个插件中，我可以指定 Docker 主机，但我不知道如何使用后者。
我的机器运行带有 Docker 工具箱的 Windows 7，因此本地主机上没有 Docker 守护程序。
上的文档dockerfile-maven-plugin似乎没有解释如何做到这一点。
- 起初，maven 输出表明它正在尝试连接到 localhost:2375。
- 我已将虚拟框中的端口转发更改为在 docker 机器上将 127.0.0.1:2375 转发到 2376。这似乎不起作用。
我已按照以下说明进行操作：
set DOCKER_CERT_PATH=%USERPROFILE%\.docker\machine\machines\default set DOCKER_HOST=tcp://192.168.99.100:2376 set DOCKER_MACHINE_NAME=default set DOCKER_TLS_VERIFY=1我设置了 DOCKER_HOST 环境变量并检查了我的 docker 机器输出：
$ docker-machine.exe ls NAME ACTIVE DRIVER STATE URL SWARM DOCKER ERRORS default * virtualbox Running tcp://192.168.99.100:2376 v17.06.1-ce这会导致 Maven 输出尝试连接到 192.168.99.100:2376 上的 docker-machine，并在机器未运行时失败。这会在机器实际运行时产生不同的输出（由 wget 确认，文件为空）：
