I am trying to modify a Dockerfile that contained a command
docker container run --rm \ -v "$PWD":/home/gradle/project \ -v "$HOME"/.gradle-docker:/root/.gradle \ ...
to be usable on Windows.
I replaced the $HOME by “~” which amazingly was accepted. Whether it also works still remains to be seen. If not I will try %HOME%.
But since there is no “PWD” env-variable in windows I wanted to replace that with “.” (i.e. the current directory), but then docker barfs at me:
docker: Error response from daemon: create .: volume name is too short, names should be at least two alphanumeric characters.
IMHO that check for >=2 characters is simply wrong! I guess the programmer had “C:” or something similar as minimal path in mind. But ‘.’ is a perfectly valid path!
How do I trick docker to accept “.” as valid directory?
