文章数量:1202371

I'm working on a docker compose where I'm trying to mount a host directory to container directory but I'm getting the following error;

docker compose up --build

Error response from daemon: invalid volume specification: '/c/Users/savi/Documents/test/test-base/vp:C:\inetpub\wwwroot:rw'

As you can see, I'm trying to mount my host directory C:\Users\savi\Documents\test\test-base\vp to container directory C:\inetpub\wwwroot

I'm on windows and running docker desktop

PS C:\Users\savi> docker compose version
Docker Compose version v2.31.0-desktop.2

Here is my docker-compose.yaml but the issue I'm referring to is related to the iisserver

services:
  sqlserver:
    build:
      context: ./sql/
      dockerfile: dockerfile.bak
    container_name: sqlserver
    ports:
      - "1433:1433"
    environment:
      sa_password: "mypassword"
      ACCEPT_EULA: "Y"
    volumes:
      - sql_data:C:/Database

  iisserver:
    build:
      context: ./
      dockerfile: dockerfile.iisbase1
    container_name: iisserver
    ports:
      - "8080:80"
    volumes:
      - C:\Users\savi\Documents\test\test-base\vp:C:\inetpub\wwwroot

    depends_on:
     - sqlserver

volumes:
  sql_data:
    driver: local

    Directory: C:\Users\savi\Documents\test\test-base

It seems to me that when picking up the host file path, it is adapting to a linux format ('/c/Users/savi/Documents/test/test-base/.) even though I'm not in the linux container mode

What I have tried..

I added the following environment variable both into the $PATH and as a .env after referring here -

echo $env:COMPOSE_CONVERT_WINDOWS_PATHS
1

Tried to add this as a bind in docker compose

volumes:
  - type: bind
    source: C:\Users\savi\Documents\test\test-base\vp
    target: C:\inetpub\wwwroot

I also tried different way of stating the path as follows

volumes:
  - "C:\\Users\\savi\\Documents\\test\\test-base\\vp:C:\\inetpub\\wwwroot"

volumes:
  - "./test-base/vp:C:\\inetpub\\wwwroot"

volumes:
  - "C:/Users/savi/Documents/test/test-base/vp:C:/inetpub/wwwroot"

Unfortunately, I don't have any luck so far.

Before I post here read almost all the posts that Google gave me with my prompt but I couldn't find anything solid that I could use to fix this issue

Here are some articles I have read

Any assistance on this is greatly appreciated!

Sorted by: Reset to default 0

This issue got fixed after setting the COMPOSE_CONVERT_WINDOWS_PATHS=0

You can add that into a .env file in the directory where your docker-compose.yaml is located. For a quick test, you can add that into your $PATH with $env:COMPOSE_CONVERT_WINDOWS_PATHS="0"
