title: How to edit files in a docker container when you don't have any text editor and you're not root?
body: <p>I'm stuck at the login screen of Jenkins because I don't remember the username and the password to log in. I read in this article <a href="https://www.serverlab.ca/tutorials/linux/administration-linux/how-to-reset-jenkins-admin-users-password/" rel="nofollow noreferrer">https://www.serverlab.ca/tutorials/linux/administration-linux/how-to-reset-jenkins-admin-users-password/</a> that it is possible to solve this problem by editing the config.xml file.</p>
  <p>But my problem is I don't have any text editor (vi, nano, emacs) and I can't install one with apt because I'm not root.</p>
  <p>Anyone knows how to solve this issue ?</p>
  <p>Thx !</p>
