本文介绍如何在 Docker Desktop for Mac 中暴露默认未提供的 2375 TCP 端口，并提供了一个示例命令来实现这一操作。此外还展示了如何通过 curl 命令检查 Docker Engine 的版本。

根据官方的文档Docker Desktop on Mac vs. Docker Toolbox, Docker Desktop on Mac只提供了UNIX socket/var/run/docker.sock, 并未提供tcp的监听(默认2375端口).
如果使用linux的配置方式在Docker Desktop中配置host, Docker Desktop将无法启动.需要去~/.docker/daemon.json中删除hosts配置才能正常启动.
通过下面的方式暴露出2375的tcp

docker run --rm -d -v /var/run/docker.sock:/var/run/docker.sock -p 127.0.0.1:2375:2375 bobrik/socat TCP-LISTEN:2375,fork UNIX-CONNECT:/var/run/docker.sock

然后通过docker version查看当前的docker engine的版本, 比如1.40. 查看官方的Engine API文档: https://docs.docker.com/engine/api
搜索个镜像测试一下:

$curl -XGET http://127.0.0.1:2375/version | python -mjson.tool
