title: How to redirect build output to a file?
body: <p>I'm trying to store the logs of the build process in a file from this command for example:</p>
  <pre class="lang-sh prettyprint-override"><code>docker build -t python:3.8.5 . --progress=plain
  </code></pre>
  <p>Would expect to work with this command:</p>
  <pre class="lang-sh prettyprint-override"><code>docker build -t python:3.8.5 . --progress=plain &gt;&gt; builder.log
  </code></pre>
  <p>Can't find in the doc how to do it.</p>
  <p>Thanks for your help.</p>
