<p>I’ve been running a Java Minecraft world (with Bedrock players via <strong>Geyser</strong>) in <code>tmux</code>. I moved it to Docker for easier updates, backups, and restarts. Along the way I hit:</p>
<ul>
<li><code>failed to register layer: ... no space left on device</code></li>
<li>Client saying: <strong>“Outdated client, please use 1.21.9 Pre-Release 2”</strong></li>
<li>Wanting config in a neat <code>.env</code> and <strong>no whitelist</strong></li>
</ul>
<p>Here’s exactly what I did.</p>
