I am trying to dockerize a PHP application. In the dockerfile, I download the archive, extract it, etc.
Everything works fine. However, if a new version gets released
I have same issue on my Windows 8.1
It turned out that it was due to case-sensitivity of path.
I called docker-compose up from directory cd /c/users/alex/ and inside container a file was turned into directory.
But when I did cd /c/Users/alex/ (not Users capitalized) and called docker-compose up from there, it worked.
In my system both Users dir and Alex dir are capitalized, though it seems like only Users dir matter.
