I try to build a simple image that uses the alpine linux image and prints "Hello StackOverflow!". What is the issue here?

Windows PowerShell:

failed to solve with frontend dockerfile.v0: failed to read dockerfile: open /var/lib/docker/tmp/buildkit-mount632819289/Dockerfile: no such file or directory

The path of where the dockerfile is stored: C:\dfiles

The code in my Dockerfile.txt:

FROM alpine
CMD ["echo", "Hello StackOverflow!"]
docker-build docker

Simple

Use just Dockerfile with no Extention instead of Dockerfile.txt

The code in my Dockerfile.txt

The file needs to be called "Dockerfile", not "Dockerfile.txt". So remove the file extension from your file and try again.
