Can’t find Dockerfile even though it’s there?
I was using VS Code to create dockerfiles and used the common “Dockerfile” name so that I can use the simply “docker build” command. Even though I didn’t specify it, VS Code added a “.dockerfile” extension. So Docker found “Dockerfile.dockerfile” instead of “Dockerfile”.
Using the -f option worked, but also simply removing the .dockerfile extension. Admittedly, took longer than it should have to realize why Docker couldn’t find the file…
