title: Dockerfile Copy not working for Nextcloud container
body: <p>I'm trying to deploy a Nextcloud container, where the config is copied from the local directory to the container. I'm not getting any error when building or running the container, and I can see the steps are successfully executed per the terminal. Regardless, the copied file simply is not in the container. What's going on here?</p>
  
  <p>Dockerfile:</p>
  
  <pre><code>FROM nextcloud:latest
  
  # Copy local config
  COPY ./config.php /var/www/html/config
  </code></pre>
  
  <p>All the evidence:
