Note that the docker build context in this case only contains the Dockerfile from STDIN. So it's not possible to COPY/ADD files from the current working directory to the image.

If you need files from the current working directory use this instead:

docker build -t $IMAGE_NAME -f - . << EOF
FROM alpine:latest
...
COPY . /
EOF
