title: Docker Rootless in Docker Rootless, It's possble?
body: <p>For my job, I would like to run <code>Jenkins</code> and <code>Docker Rootless</code> (with the sysbox runtime only for this container), all in <code>Docker Rootless</code>.</p>
  <p>I would like this because I need a secure environment given I don't inspect Jenkins pipelines</p>
  <p>But when I run docker rootless in docker rootless, I get this error:</p>
  <pre><code>[rootlesskit:parent] error: failed to setup UID/GID map: newuidmap 54 [0 1000 1 1 100000 65536] failed: newuidmap: write to uid_map failed: Operation not permitted
  : exit status 1
  </code></pre>
  <p>I tried many actions but failed to get it to work. Someone would have a solution to do this, please?</p>
  <p>Thanks for reading me, have a nice day!</p>
