Mount current directory as a volume in Docker on Windows 10

Question

Description  I am using Docker version 1 12 5 on Windows 10 via Hyper-V and want to use container executables as commands in the current path  I built a Docker image that is running fine  but I have a problem to mount the current path  The idea is to create an alias and do a docker run --rm       command so that it could be used system-wide in the current directory   Setup  I have a drive E with a folder  test  and in there a folder called  folder on windows host  to show that the command is working  The Dockerfile create the directory  data  defines it as VOLUME and WORKDIR   Having E  test as the current directory in PowerShell and executing the Docker command with an absolute path  I can see the content of E  test   PS E  test gt  docker run --rm -it -v E  test  data mirkohaaser docker-clitools ls -la total 0 drwxr-xr-x 2 root root 0 Jan  4 11 45   drwxr-xr-x 2 root root 0 Jan  5 12 17 folder on windows host   Problem  I want to use the current directory and not an absolute notation  I could not use pwd in the volume because of different error messages   Trying with   pwd   PS E  test gt  docker run --rm -it -v   pwd   data mirkohaaser docker-clitools ls -la C  Program Files Docker Docker Resources bin docker exe  Error parsing reference     data  is not a valid repository tag  See  C  Program Files Docker Docker Resources bin docker exe run --help     Trying with    pwd   PS E  test gt  docker run --rm -it -v    pwd   data mirkohaaser docker-clitools ls -la C  Program Files Docker Docker Resources bin docker exe  Error parsing reference   E   test  is not a valid repository tag  See  C  Program Files Docker Docker Resources bin docker exe run --help     Trying with    pwd     PS E  test gt  docker run --rm -it -v    pwd    data mirkohaaser docker-clitools ls -la C  Program Files Docker Docker Resources bin docker exe  Error response from daemon  Invalid bind mount spec    E   test    data   invalid mode   data  See  C  Program Files Docker Docker Resources bin docker exe run --help     Trying with  pwd   PS E  test gt  docker run --rm -it -v   pwd   data mirkohaaser docker-clitools ls -la C  Program Files Docker Docker Resources bin docker exe  Error response from daemon  create  pwd    pwd  includes invalid characters for a local volume name  only   a-zA-Z0-9  a-zA-Z0-9  -   are allowed  See  C  Program Files Docker Docker Resources bin docker exe run --help     What is the correct syntax of mounting the current directory as a volume in Docker on Windows 10

Command prompt  Cmd exe  When the Docker CLI is used from the Windows Cmd exe  use  cd  to mount the current directory  echo test  gt  test txt docker run --rm -v  cd   data busybox ls -ls  data test txt  Git Bash  MinGW  When the Docker CLI is used from the Git Bash  MinGW   mounting the current directory may fail due to a POSIX path conversion  Docker mounted volume adds  C to end of windows path when translating from linux style path  Escape the POSIX paths by prefixing with   To skip the path conversion  POSIX paths have to be prefixed with the slash     to have leading double slash       including    pwd  touch test txt docker run --rm -v    pwd   data busybox ls -la   data test txt  Disable the path conversion Disable the POSIX path conversion in Git Bash  MinGW  by setting MSYS NO PATHCONV 1 environment variable at the command level touch test txt MSYS NO PATHCONV 1 docker run --rm -v   pwd   data busybox ls -la  data test txt  or shell  system  level export MSYS NO PATHCONV 1 touch test txt docker run --rm -v   pwd   data busybox ls -la  data test txt

For Git Bash for Windows  in ConEmu   the following works for me  for Docker Windows containers    docker run --rm -it -v  pwd -W  c  api microsoft dotnet 2-runtime   Note the backticks backquotes around pwd -W    With all other variations of PWD I ve tried I ve received   Error response from daemon  invalid volume specification        Update  The above was for Docker Windows containers  for Linux containers use   docker run --rm -it -v  pwd -W   api -p 8080 80 microsoft aspnetcore 2

This command should fix it   docker run --rm -it -v   PWD  c  data mirkohaaser docker-clitools   PWD  is the host current folder  after the   is the container folder   If the mounting is correct then files will be listed in the director c  data in the container

Other solutions for Git Bash provided by others didn t work for me  Apparently there is currently a bug limitation in Git for Windows  See this and this   I finally managed to get it working after finding this GitHub thread  which provides some additional solutions if you re interested  which might work for you  but didn t for me    I ended up using the following syntax   MSYS NO PATHCONV 1 docker run --rm -it -v   pwd   usr src project gcc 4 9   Note the MSYS NO PATHCONV 1 in front of the docker command and   pwd  - round brackets  lower-case pwd  no quotes  no backslashes   Also  I m using Linux containers on Windows if that matters    I tested this in the new Windows Terminal  ConEmu and GitBash  and all of them worked for me

You need to swap all the back slashes to forward slashes so change  docker -v C  my folder  mountlocation       to   docker -v C  my folder  mountlocation      I normally call docker from a cmd script where I want the folder to mount to be relative to the script i m calling so in that script I do this     SETLOCAL  REM capture the path to this file so we can call on relative scrips REM without having to be in this dir to do it   REM capture the path to  0 ie this script set mypath   dp0  REM strip last char set PREFIXPATH  mypath  0 -1   echo  PREFIXPATH  PREFIXPATH   mkdir -p  PREFIXPATH  my folder to mount  REM swap   for   in the path REM because docker likes it that way in volume mounting set PPATH  PREFIXPATH      echo  PPATH  PPATH    REM pass all args to this script to the docker command line with    docker run --name mycontainername --rm -v  PPATH  my folder to mount  some mountpoint  myimage     ENDLOCAL

Open Settings on Docker Desktop  Docker for Windows   Select Shared Drives  Select the drive that you want to use inside your containers  e g   C   Click Apply  You may be asked to provide user credentials    The command below should now work on PowerShell  command prompt does not support   PWD     docker run --rm -v   PWD   data alpine ls  data   IMPORTANT  if when you change your Windows domain password  the mount will stop working silently  that is  -v will work but the container will not see your host folders and files  Solution  go back to Settings  uncheck the shared drives  Apply  check them again  Apply  and enter the new password when prompted

In Windows Command Line  cmd   you can mount the current directory like so   docker run --rm -it -v  cd   usr src project gcc 4 9   In PowerShell  you use   PWD   which gives you the current directory   docker run --rm -it -v   PWD   usr src project gcc 4 9   On Linux   docker run --rm -it -v   pwd   usr src project gcc 4 9   Cross Platform  The following options will work on both PowerShell and on Linux  at least Ubuntu    docker run --rm -it -v   PWD   usr src project gcc 4 9 docker run --rm -it -v   pwd   usr src project gcc 4 9
