persist %USERPROFILE% folder using docker compose volume

Question

I am searching on how to persist user profile folder in volume mounting

I have folder C:\Users\ABEL\source\repos which needs to be persisted for a windows container. The username should be from the host. It is unknown.

Below is my docker-compose file, The volume section is not correct. Any comments will be helpful. Thanks in advance

version: '3.4'

services:
  directoryservice:
    image: abc-directoryservice:latest
    build: .
    ports:
      - "44309:44309"
    environment:
      - ASPNETCORE_ENVIRONMENT=Development
      - ASPNETCORE_URLS=https://+:44309;
      - ASPNETCORE_Kestrel__Certificates__Default__Password=welcome123#
      - ASPNETCORE_Kestrel__Certificates__Default__Path=/https/aspnetapp.pfx
    volumes:
      - ./devops/https/abccert.pfx:/https/aspnetapp.pfx:ro
      # - "$env:USERPROFILE/source:$env:USERPROFILE/source"
      - ${Env:USERPROFILE}\source:${Env:USERPROFILE}\source

I get below error

invalid interpolation format for services.directoryservice.volumes.[]: "${Env:USERPROFILE}\\source:${Env:USERPROFILE}\\source". You may need to escape any $ with another $.

The $env:USERPROFILE/ ${env:USERPROFILE} syntax is specific to PowerShell.

Judging by the docs, docker-compose uses its own syntax: $USERPROFILE / ${USERPROFILE}

You report a follow-up problem, namely that the Windows-style path stored in $USERPROFILE (%USERPROFILE%) (e.g. C:\Users\jdoe\source) isn't converted to a Unix-style path (e.g. c/Users/jdoe/source)

This answer suggests that you must set environment variable COMPOSE_CONVERT_WINDOWS_PATHS to 1, before running your docker-compose command.

E.g., in a PowerShell session:

$env:COMPOSE_CONVERT_WINDOWS_PATHS=1

Consider adding this statement to your $PROFILE file so that it takes effect in future PowerShell sessions too.
