title: Docker build "path . not found"
body: <p>I'm trying to make my first docker container</p>
  
  <p>I installed dokcer-ce, following docker tutorial for ubuntu.</p>
  
  <p>I create a folder and put my Dockerfile in it.</p>
  
  <pre><code>FROM docker/whalesay
  
  RUN apt-get update &amp;&amp; apt-get install -y figlet fortune &amp;&amp; rm /var/apt/*
  
  CMD figlet "Hy SUPINFO" | cowsay -n &amp;&amp; /usr/games/fortune -a | cowsay
  </code></pre>
  
  <p>In this folder I made a :</p>
  
  <pre><code>sudo docker build -t whalesupinfo .
  </code></pre>
  
  <p>I always have this output</p>
  
  <pre><code>unable to prepare context: path "." not found
  </code></pre>
  
  <p>EDIT: I was in sshd, not working into it ?!</p>
