title: What is the default user for Linux Alpine?
body: <p>I am running a Dockerfile here and want to "change back" to the regular Linux Alpine user, after following <a href="https://sysadmins.co.za/dockerizing-a-memcached-server-for-docker-on-alpine/" rel="noreferrer">this</a> to setup memcached.</p>
  
  <pre><code>FROM python:3.6-alpine
  
  # Bunch of Linux / Django / Node stuff
  
  COPY boot.sh /boot.sh
  RUN apk --no-cache add memcached &amp;&amp; chmod +x /boot.sh
  
  USER memcached
  CMD ["/boot.sh"]
  
  # Change back to default user here
  USER root
  
  ADD docker-entrypoint.sh
  ENTRYPOINT ["/docker-entrypoint.sh"]
  </code></pre>
  
  <p>What is the syntax for this? I have used USER root for the time being. Is this correct? I don't reference <code>USER</code> anywhere before <code>USER memcached</code>. </p>
