Docker Build Command Format

In your powershell : There is this type of error because you have not specified a path whith your Dockerfile.

Try this:

$ docker build -t friendlyhello:latest -f C:\\TestDockerApp\\Dockerfile.txt

friendlyhello is the name you assign to your container and add the version , just use the :latest

-f C:\TestDockerApp\Dockerfile.txt - you want to add a tag because the build command needs a parameter or tag - The DockerFile is a text document so explicitly add the extension .txt

$ docker build -t friendlyhello:latest -f C:\\TestDockerApp\\Dockerfile.txt .**
