title: Copying all files from one docker volume to another using wild card characters?
body: <p>This works because it's copying <code>some_file</code>:</p>
  
  <pre><code>docker run --rm -v target-data:/target -v ~/source:/source alpine cp source/some_file target/
  </code></pre>
  
  <p>This does not (Using wildcard):</p>
  
  <pre><code>docker run --rm -v target-data:/target -v ~/source:/source alpine cp source/* target/
  cp: can't stat 'source/*': No such file or directory
  </code></pre>
  
  <p>How do copy all the files in the <code>souce</code> volume to the <code>target</code> volume?</p>
