title: Docker with Windows
body: <p>I am new to Docker. I operate it on my Windows 10.
  Started jenkins in interactive mode at <code>/bin/bash</code>, and i want to open the file <code>InitialAdminPassword</code> located at <code>/var/jenkins_home/secrets/</code></p>
  
  <p>How do i open this file?</p>
  
  <p><code>sudo</code> doesn't work, and using <code>apt-get</code> gives the error:</p>
  
  <blockquote>
    <p>E: Could not open lock file /var/lib/dpkg/lock - open (13: Permission denied)
    E: Unable to lock the administration directory (/var/lib/dpkg/), are you root?</p>
  </blockquote>
  
  <p>Also how do i find the location of my <code>Dockerfile</code>?</p>
