Can't build, reports : "Error: the Dockerfile (Dockerfile) can't be empty. However it exists within same dir

[danieldram]

I am not sure how to solve this issue.. I tried for an hour.
I uninstalled previous versions of Docker and docker-compose, I reinstalled the new docker for macosx.

The dir structure ha both the docker-compose.yml and Dockerfile in the same directory, here are the files:
#Dockerfile

FROM node:latest
MAINTAINER Daniel Ram
COPY . /var/www
WORKDIR /var/www

RUN npm install
EXPOSE 3000
CMD ["npm", "start"]

#docker-compose.yml

version: '2'
services:
  playthis_server:
    build:
      context: .
      dockerfile: Dockerfile
    logging:
      driver: "json-file"
      options:
          max-size: "1000m"
          max-file: "10"
    ports:
        # - "80:3000"
        - "3003:3003"
    restart: "always"
    networks:
        - app
networks:
  app:
    driver: bridge

After running this command, it fails to build:

$docker-compose up -d

Any ideas on how to solve this issue?

I figured out the problem.... In Dockerfile.

COPY

is now

ADD

can be closed.. :|

I have a problem with the same error and I don't know how could I solve it. :(

I had a similar problem and the solution was to save the file again with the modifications

I too face that same problem. Enable autosave in Visual Studio code and build. it will run without any errors.

I'm too face that same problem. Save the docker file, then try again. Enable autosave in Visual Studio code and build. it will run without any errors.
