title: Docker build Error: no such file or directory
body: <p>I am trying to do a basic docker learning and building an image. </p>
  
  <p>My directory structure currently looks like below: </p>
  
  <pre><code>/Documents/docker_test/
  ├── docker_python
  ├── hello_world.py
  </code></pre>
  
  <p>The file <code>docker_python</code> is the docker file name. <code>hello_world.py</code> is a basic hello_world python script I am trying to run it by default when the container is created of the image. </p>
  
  <p>The contents of that docker file look like below: </p>
  
  <pre><code>### Dockerfile 
  
  # Created by Baktawar
  
  # Pulling from base Python image

  LABEL maintainer=”Baktawar”
  
  # Set the working directory of the docker image 
  WORKDIR /app
  COPY . /app
  
  
  # packages that we need
  RUN pip install numpy &amp;&amp; \
      pip install pandas &amp;&amp; \
      pip install jupyter
