docker-machine create-創建機器時出錯：運行配置錯誤：ssh命令錯誤

Question

我正在關注Docker入門文檔，但我陷入了第4部分的開頭（ https://docs.docker.com/get-started/part4/ ）。

我在Windows 10上，應該設置幾個本地VM。 我創建了名為"myswitch"的虛擬"myswitch" ，但是當我運行時

docker-machine create -d hyperv --hyperv-virtual-switch "myswitch" myvm1

它給我以下錯誤

c:\srv> docker-machine create -d hyperv --hyperv-virtual-switch "myswitch" myvm4

我在提升的命令外殼中運行（我也嘗試過使用powershell作為管理員，結果完全相同）。

docker docker-machine ls給出以下結果（myvm1和-2來自我的第一次嘗試）：

c:\srv> docker-machine ls
NAME    ACTIVE   DRIVER   STATE     URL                        SWARM   DOCKER    ERRORS

我無法繼續本教程的下一步：

c:\srv> docker-machine ssh myvm3 "docker swarm init --advertise-addr 192.168.1.140"
Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running?
exit status 1

有什么建議么？

Answer 1

您是在Windows上運行Docker Toolbox還是Docker？

如果它的Docker在Windows上，我會看到docker-machine create被錯誤地定向為在“ /var/lib/boot2docker/ca.pem”生成證書。 這是特定於boot2docker的位置。我傾向於相信系統中還剩下Docker Toolbox的痕跡，或者您需要清除以下env變量。

DOCKER_TLS_VERIFY

DOCKER_CERT_PATH

DOCKER_HOST

DOCKER_TOOLBOX_INSTALL_PATH

Docker初始化將無法在unix：///var/run/docker.sock上找不到套接字，這是預期的，因為docker守護進程不在此位置。

Answer 2

首先，請確保Hyperv的外部虛擬交換機已連接到適當的以太網（或）Wi-Fi適配器。 參考下圖

現在，在Windows powershell或cmd（以管理員身份）中運行以下命令：

docker-machine --native-ssh create -d hyperv --hyperv-virtual-switch "Primary Virtual Switch" myvm1

使用--native-ssh可以防止任何隨機的ssh.exe從“其他地方”引起問題（有關詳細信息，請參閱https://github.com/docker/machine/issues/3511 ）。
