title: How to copy file from host to container using Dockerfile
body: <p>I have written a Dockerfile which looks like this</p>
  
  <pre><code>FROM ubuntu:12.04
  
  RUN apt-get update
  RUN apt-get install -y wget
  </code></pre>
  
  <p>Now I'm having a file called <code>abc.txt</code> in my host machine. How can I copy it to this container. Is there any step that I can add in Dockerfile which copy from Host to Container.</p>
