Docker Toolbox(Windows):无效的卷规格 [英] Docker Toolbox (Windows): invalid volume specification

问题描述

配置

使用Windows 10，Docker工具箱(非本机Docker，以便能够使用VM).

背景

有一个Python(2.7)脚本应该运行Docker容器.代码如下:

  self.docker.containers.run('container_name'，command ='bash -c％s"'％命令，volume = {PROJECT_PATH:{'bind':'/shared'，'mode':'rw'}}，working_dir ='/shared'，remove = True，** kwargs) 

问题

尝试运行脚本:

  *构建DummyProbe泊坞窗映像*运行DummyProbe容器500服务器错误:内部服务器错误(无效的卷规范:'C:\ Users \ Foo \ ..:/shared:rw'") 

想法

在网上搜索后，无效的卷规范似乎是由Windows和Linux处理目录结构的方式引起的.Linux使用斜杠/，而Windows使用反斜杠 \ .类似的问题:

• Docker Toolbox

    $ docker-machine env导出DOCKER_TLS_VERIFY ="1"导出DOCKER_HOST ="tcp://111.111.11.111:1111"导出DOCKER_CERT_PATH ="C:\ Users \ Foo \ .docker \ machine \ machines \ default"导出DOCKER_MACHINE_NAME =默认"导出COMPOSE_CONVERT_WINDOWS_PATHS ="true"#运行以下命令以配置您的shell:#eval $("C:\ Program Files \ Docker Toolbox \ docker-machine.exe" env) 

  其他问题中的任何建议都行不通.

  更新

  试图用/替换 \ 并在脚本中使用它:

    500服务器错误:内部服务器错误(无效的卷规范:'C:/Users/***/..:/shared:rw'") 

  所以看来这不是问题

  解决方案

  我能够通过用/和 C替换所有 \\ 来完成这项工作:和/c .

  断开路径: C:\\ Path \\ to \\ file 变成/c/path/to/file

  https://docs.python.org/2/library/os.html

  似乎负责返回系统路径的 os 模块没有将Windows转换为Unix路径的内置函数.Docker Toolbox也无法处理这种对话(即使可以的话).

  也许还有其他一些优雅的方法可以完成这项工作.但是现在只使用这个.

  Configration

  Using Windows 10, Docker Toolbox (not native Docker, to be able to use VMs).

  Background

  There is a Python (2.7) script that is supposed to run a Docker container. The code looks like this:

  self.docker.containers.run('container_name',
                             command='bash -c "%s"' % command,
                             volumes={PROJECT_PATH: {'bind': '/shared', 'mode': 'rw'}},
                             working_dir='/shared',
                             remove=True,
                             **kwargs)
  

  Problem

  Trying to run the script:

  * Building the DummyProbe docker image
  * Running the DummyProbe container   
  500 Server Error: Internal Server Error ("invalid volume specification: 'C:\Users\Foo\..:/shared:rw'")
  

  Thoughts

  After searching the web the invalid volume specification is seems to be caused by the way Windows and Linux handle directory structure. Linux uses slashes / while Windows - back-slashed \. Similar questions:

  • Docker Toolbox Windows - Invalid volume specification
  • Invalid volume specification trying to run portainer container

  However in my case the COMPOSE_CONVERT_WINDOWS_PATHS is set (to true, tried setting to 1 as well):

  PowerShell

  Docker Toolbox

  $ docker-machine env
  export DOCKER_TLS_VERIFY="1"
  export DOCKER_HOST="tcp://111.111.11.111:1111"
  export DOCKER_CERT_PATH="C:\Users\Foo\.docker\machine\machines\default"
  export DOCKER_MACHINE_NAME="default"
  export COMPOSE_CONVERT_WINDOWS_PATHS="true"
  # Run this command to configure your shell:
  # eval $("C:\Program Files\Docker Toolbox\docker-machine.exe" env)
  

  None of the suggestions in other questions work.

  Update

  Tried to use to replace \ with / and use it in script:

  500 Server Error: Internal Server Error ("invalid volume specification: 'C:/Users/***/..:/shared:rw'")
  

  So it seems like it is not an issue

  解决方案

  I was able to make this work by replacing all \\ with / and C: with /c.

  The broken path: C:\\Path\\to\\file becomes /c/path/to/file

  https://docs.python.org/2/library/os.html

  It seems that os module which is responsible for returning system paths doesn't have a built-in func to convert Windows to Unix path. And the Docker Toolbox doesn't handle this converstion as well (if it even should).

  May be there is some other elegant way to make this work. But for now going to just use this one.
