While Deployments are ideal for stateless applications, many real‑world use cases require stateful behavior — applications that store data, maintain identity, and rely on stable storage.</p> <p>This is where StatefulSets come in. They provide stable identity, stable storage, and ordered deployment for stateful applications.</p> <h1 id="table-of-contents">Table of Contents</h1> <nav id="TableOfContents"> <ol> <li><a href="#why-statefulsets">Why StatefulSets?</a></li> <li><a href="#examples-of-stateful-systems">Examples of Stateful Systems</a></li> <li><a href="#create-statefulset">Create Statefulset</a></li> <li><a href="#service">Service</a></li> <li><a href="#volume">Volume</a></li> <li><a href="#ordered-creation--scaling">Ordered Creation &amp; Scaling</a></li> <li><a href="#ordered-deletion">Ordered Deletion</a></li> </ol> </nav> <h3 id="why-statefulsets">Why StatefulSets?</h3> <p>Stateless apps don’t care which instance serves a request.
