A pod that vanishes at 3am, a service that goes sluggish under load for no obvious reason, a node that grinds to a halt — nine times out of ten the root cause is a <code>requests</code> value someone copied from a tutorial and a <code>limits</code> value nobody thought about. So let me walk through how this actually works, because the scheduler&rsquo;s behaviour is not intuitive until you&rsquo;ve been burned by it.</p>Mon, 08 Sep 2025 10:00:00 +0000
