Windows 10 安装 Docker Machine笔记

说结论,再谈折腾过程。

结论:
Docker 在 Linux 系统下很好用,但并不适合在 Windows 系统下使用。想在 windows 下使用 docker ,可尝试使用 Linux 虚拟机安装运行 docker。

之前使用 Docker 容器一直是在 Linux 系统环境下,但平时开发都是 windows10 系统。
于是有个想法,想在 win10 下安装 docker 开发环境,来统一生产环境和开发环境。

折腾过程:

安装 Docker Machine 之前,要先安装 Docker for Windows。
安装 docker 引擎,得先开启 CPU虚拟化 支持和 Hyper-V 功能。

安装 docker machine 启动报错,提示 virtualbox 和 Hyper-V 不能共存。

$ docker-machine create --driver virtualbox default
Running pre-create checks...
Error with pre-create check: "This computer is running Hyper-V. VirtualBox won't boot a 64bits VM when Hyper-V is activated. Either use Hyper-V as a driver, or disable the Hyper-V hypervisor. (To skip this check, use --virtualbox-no-vtx-check)"

docker-machine 默认以 virtualbox 驱动模式,即 --driver virtualbox 创建 docker 虚拟机。
但64位的virtualbox虚拟机,在已开启 Hyper-V 功能的windows环境下,是无法启动的。
现在实际上有 2个方案

  1. 改用 Hyper-V 驱动运行 docker-machine 命令。(正确)
  2. 关闭 Hyper-V 功能,然后再正常启动 docker-machine。(错误)

网上的教程,基本上都第2种,关闭 Hyper-V ,需要重启电脑,耗时费力,搞到最后,连 docker 都启动不了。因为 windows 下的 Docker 引擎依赖 Hyper-V 功能。

关闭 Hyper-V 功能

控制面板--程序--程序和功能--启用和关闭 Windows 功能--取消勾选 Hyper-V 功能。

docker-machine create --driver virtualbox test
This computer doesn't have VT-X/AMD-v enabled

都说是 CPU虚拟化支持没开启,但确实已经打开了。网上说你的 Hyper-V 没有关闭成功,得使用 bcdedit 命令查看。还必须得 以管理员身份运行 CMD 命令才行。

bcdedit
......
hypervisorlaunchtype    Auto

执行如下命令,关闭改选项,并重启电脑

bcdedit /set hypervisorlaunchtype off

https://blog.csdn.net/u012865169/article/details/103720545/

上面一波关闭 Hyper-V 操作之后,成功地导致了 Docker Engine 启动失败。提示如下:

Hardware assisted virtualization and data execution protection must be enabled in the BIOS. See https://docs.docker.com/docker-for-windows/troubleshoot/#virtualization

开启 Hyper-V 功能

控制面板--程序--程序和功能--启用和关闭 Windows 功能--勾选 Hyper-V 功能。

因为前面 bcdedit 命令把 hypervisorlaunchtype 项关闭了,必须执行命令手动开启,并重启电脑,Hyper-V 功能才能正常运行。以管理员身份运行如下命令:

bcdedit /set hypervisorlaunchtype auto

没想到百度到的技术文章,是这么不靠谱。后面自己看了下官方文档,其实是有说明的。

官方文档

Get started with Docker Machine and a local VM

IF YOU ARE USING DOCKER DESKTOP FOR WINDOWS

Docker Desktop for Windows uses Microsoft Hyper-V for virtualization,
and Hyper-V is not compatible with Oracle VirtualBox. Therefore, you
cannot run the two solutions simultaneously. But you can still use
docker-machine to create more local VMs by using the Microsoft Hyper-V
driver.

Windows 下的 Docker 桌面版,使用 Hyper-V 功能实现虚拟化,但Windows 下的 Hyper-V 功能与 Oracle公司的 VirtualBox 产品不兼容。因此,两种解决方案不可并存。

所以,只能使用 Hyper-V 方案,通过 docker-machine 命令来创建本地虚拟机。

The prerequisites are:

Have Docker Desktop for Windows installed, and running (which requires
that virtualization and Hyper-V are enabled, as described in What to
know before you install Docker Desktop for Windows).

Set up the Hyper-V driver to use an external virtual network switch
See the Docker Machine driver for Microsoft Hyper-V topic, which
includes an example of how to do this.

开启虚拟化支持,创建虚拟交换机

使用 Hyper-V 方案创建 Docker 虚拟机之前,必须进行两项准备:

  1. 安装并运行 docker windows 桌面版(BIOS开启CPU虚拟化支持,开启 Hyper-V 功能)
  2. 通过 Hyper-V 管理器,设置一个 外部网络虚拟交换机

微软Hyper-V方案运行docker-machine https://docs.docker.com/machine/drivers/hyper-v/
https://docs.docker.com/machine/get-started/


$ docker-machine create --driver hyperv vm
Running pre-create checks...
Error with pre-create check: "Hyper-v commands have to be run as an Administrator"

必须以超级管理员身份运行,否则会有上面的提示。必须先通过 Hyper-V 管理器 创建一个 外部网络 虚拟交换机,否则运行 docker-machine 会有如下报错:

docker-machine create --driver hyperv vm
Running pre-create checks...
Error with pre-create check: "no External vswitch found. A valid vswitch must be available for this command to run. Check https://docs.docker.com/machine/drivers/hyper-v/"

按官网说明,一切准备就绪。但还是报错,因为天朝网络太卡了,初次使用时,下载 Boot2Docker IOS 文件失败。

docker-machine create --driver hyperv vm
Running pre-create checks...
(vm) No default Boot2Docker ISO found locally, downloading the latest release...
Error with pre-create check: "Get https://api.github.com/repos/boot2docker/boot2docker/releases/latest: read tcp 192.168.3.8:52998->192.30.255.117:443: wsarecv: A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond.

手动下载 boot2docker.ios 文件:

https://github.com/boot2docker/boot2docker/releases/download/v18.09.8/boot2docker.iso

并将此文件拷贝到此路径下面:

C:\Users\xxx\.docker\machine\cache\

https://blog.csdn.net/gongli109/article/details/105618632/


下面 docker-machine 终于可以成功运行了。

创建docker虚拟机:

docker-machine create --driver hyperv vm

To see how to connect your Docker Client to the Docker Engine running on this virtual machine, run: docker-machine env vm

查看虚拟机环境变量:

docker-machine env vm
SET DOCKER_TLS_VERIFY=1
SET DOCKER_HOST=tcp://192.168.3.19:2376
SET DOCKER_CERT_PATH=C:\Users\yourname\.docker\machine\machines\vm
SET DOCKER_MACHINE_NAME=vm
SET COMPOSE_CONVERT_WINDOWS_PATHS=true
REM Run this command to configure your shell:
REM     @FOR /f "tokens=*" %i IN ('docker-machine env vm') DO @%i

挂载虚拟机远程文件夹到本地目录:

mkdir foo
docker-machine ssh vm mkdir foo
docker-machine mount vm:/home/docker/foo foo
You must have a copy of the sshfs binary locally to use the mount feature

上面报错了,因为挂载功能,需要用到一个 sshfs 的服务。在Windows下安装不成熟的 sshfs 服务,个人不大推荐。

Windows 10 开启 NFS 客户端 功能,是比较推荐的方案,因为win10企业版和专业版,都带有此项功能,但默认不开启。

挂载远程目录到本地X盘

mount 192.168.1.101:/es X:

Windows10配置NFS服务端和客户端 https://www.cnblogs.com/xuxy03/p/6232378.html


windows下的SSHFS

首先在GitHub上下载DokanSetup-1.0.5.1000和WinSSHFS-1.6.1.13-devel
注意:Dokan不能使用最新的版本,得使用1.0.5版本。要不win-sshfs会报Dokan版本错误的问题。(win10版本)

按照提示,安装Dokan和win-sshfs。并安装提示安装的依赖包Visual C++ Redistributable for Visual Studio 2015(x86版本)。
