title: Docker how to commit images with name on repository and tag
body: <p>I've made the images of Ubuntu 14:04, on my local laptop.
  Then I want to commit images,</p>
  
  <p>I run this command to commit</p>
  
  <pre><code> $ sudo Docker commit 2a1aef6a0547
  </code></pre>
  
  <p>However, there is no name on the repository and TAG</p>
  
  <p>Like this, check images</p>
  
  <pre><code> $ sudo docker images
  </code></pre>
  
  <p>The results</p>
