body: <p>I am new here trying to learn docker, I started this tutorial </p>

  <p>Building your image</p>
  
  <p>$ docker build -t  mlotfi/centos-node-hello .</p>
  
  <p><code>mlotfi</code> is my username in  <a href="https://hub.docker.com/" rel="nofollow">https://hub.docker.com/</a></p>
  
  <p>when I did <code>docker images</code>, I got:</p>
  
  <pre><code>REPOSITORY          TAG                 IMAGE ID            CREATED             VIRTUAL SIZE
  &lt;none&gt;              &lt;none&gt;              sha256:189cb        27 seconds ago      485.1 MB
  centos              centos6             sha256:d0a31        12 days ago         228.9 MB
  </code></pre>
  
  <p>instead of: </p>
  
  <pre><code>REPOSITORY          TAG                 IMAGE ID            CREATED             VIRTUAL SIZE
  mlotfi/centos-node-hello   latest              sha256:189cb        27 seconds ago      485.1 MB
  centos              centos6             sha256:d0a31        12 days ago         228.9 MB
  </code></pre>
  
  <p>UPDATE:
  at the end of the build I see :</p>
  
  <pre><code>Complete!

  Step 4 : COPY package.json /src/package.json

  </code></pre>
  
  <p>But I already have package.json in the src directory.</p>
