<p>My Java class uses Zybooks, which uses some software that
|
|
lets me pick what language and IDE to use, then gives me an
|
|
Ubuntu container to code in, hosted on AWS. For example, here's
|
|
<a href="https://github.com/coder/code-server">code-server</a>
|
|
with Java 11. And I also have remote desktop access over VNC via
|
|
Apache Guacamole. But more interestingly, <strong>I have root
|
|
access.</strong></p>

<p>Here's what I did:</p>
|
|
<ol type="1">
|
|
<li>Loaded up the bash + code-server environment</li>
|
|
<li>Installed and ran nginx</li>
|
|
<li>Eternally create, modify, and delete file to keep the
|
|
container alive.
|
|
<ol type="1">
|
|
<li>(In)activity detection is based off whether any files on
|
|
/usercode have been modified in <em>x</em> minutes.</li>
|
|
<li>The page also needs to be open, so I've got that running in
|
|
a little VM on my server.</li>
|
|
</ol></li>
|
|
<li>Set up remote port-forwarding from my server
|
|
<ol type="1">
|
|
<li>See <a
|
|
href="https://serverfault.com/questions/861909/ssh-r-make-target-host-accept-connection-on-all-interfaces">here</a>
|
|
for details on that.</li>
|
|
</ol></li>
|
|
<li>Have caddy reverse-proxy <a
|
|
href="https://textbook.askiiart.net">textbook.askiiart.net</a>
|
|
to the container (via the forwarded port).</li>

<p>Probably not. But if anyone knows how to run Crysis on this

thing, I'd be happy to try, <a

|
figure. Sorry if the site goes offline for a bit, but if it

does, it should be back up soon. Also, it's rather funny that my

textbook is more reliable than my actual server.</p>

<li>If you're interested, I'm running Debian 12 in a VM, all

I've got installed is Docker. I've checked journalctl, my RAM,

and I verified the installation media. I'm not sure what else to
|
|
check, but I'm certainly open to suggestions.</li>
