When you develop with docker and use bind mounts, you may encounter problems if you do ont align the uid / gid of the user in docker with teh uid / gid of your user. For this purpose, some Dockerfile propose an ARG so that you can pass in the UID/GID you need.
But how to find the right id to give ?
On linux, simply run: id
On windows, according to this stackoverflow contribution
you should open a command window and run:
for /F "tokens=1,2 delims=: " %A in ('WhoAmI /USER /FO LIST') do @if /I "%~A" == "SID" echo %B
On Mac FIXME !
