docker - 设置远程Docker服务器时出错

Question

在我的Pi上，我跟随this tutorial在raspbian上安装docker。这里的一些旁注:

我没有设置群集，我在docker info处停了下来，并且(如在其他指南中一样)我成功运行了hello world容器。

idk如果重要的话，但本指南(与其他指南不同)让我编辑/etc/apt/sources.list并添加以下行:deb https://download.docker.com/linux/raspbian/ stretch stable

在我的开发机器上(10号胜利)，我使用 this tutorial将docker config和ymls添加到了我的mern堆栈应用中。但是，在本教程的多个地方，他们希望我运行docker命令，所以最终我不得不安装Docker Desktop。
但是我不想使用本地容器，我想在Pi上使用远程容器。因此，我使用 this tutorial尝试设置了我的远程 docker 。
但是我得到一个错误:

C:\Users\oweng>docker-machine create --driver generic--generic-ip-address=192.168.1.2 --generic-ssh-key "%HOMEPATH%/.ssh/id_rsa" --generic-ssh-user=pi remote-docker-hostRunning pre-create checks...

Enter passphrase for key'C:\Users\oweng.docker\machine\machines\remote-docker-host\id_rsa':Error creating machine: Error detecting OS: OS type not recognized

我用谷歌搜索了一下错误，但是没有找到解决方法。
此外，当检查我的Pi(docker服务器)上的监听端口时，我看不到它正在运行

pi@raspberrypi:~ $ sudo lsof -i -P -n | grep LISTEN xrdp-sesm 390root 7u IPv6 14566 0t0 TCP [::1]:3350 (LISTEN) sshd
404 root 3u IPv4 17224 0t0 TCP *:22 (LISTEN) sshd
404 root 4u IPv6 17226 0t0 TCP *:22 (LISTEN) xrdp
406 xrdp 11u IPv6 17302 0t0 TCP *:3389 (LISTEN)

所以我觉得服务器可能没有运行？但这似乎是。

更新1
在 this SO之后，我似乎能够使服务器运行。编辑docker.service文件。我现在在尝试创建时遇到了另一个错误

C:\Users\oweng>docker-machine create --driver generic--generic-ip-address=192.168.1.2:2137 --generic-ssh-key "%HOMEPATH%/.ssh/id_rsa" --generic-ssh-user=pi remote-docker-hostRunning pre-create checks...

BMitch的评论将我引向了这两个教程，这似乎正是我想做的

我不会为此使用docker-machine。对该工具的支持似乎正在消失，并且有许多更简单的方法。
最简单的方法是将计算机上的DOCKER_HOST设置为远程节点的ssh设置:

export DOCKER_HOST=ssh://user@host
docker info # should now show the remote host if you have ssh access

如果您发现自己在节点之间进行了大量更改，建议您设置一个上下文，然后将DOCKER_HOST保持未设置状态:

unset DOCKER_HOST
docker context create rpi --description "Pi" --docker "host=ssh://user@host"
docker --context rpi info

然后，您可以通过以下方式使上下文成为新的默认值:

docker context use rpi

然后切换回本地/默认docker引擎

docker context use default
