<p>Does Kubernetes have any strategy of picking which older version pods to be deleted during rolling update? I didn't find any existing documents describing this.</p>

<p>Pods are supposed to be ephemeral and disposable, and thus if you <em>do</em> care about their ordering, you'd want to use a <a href="https://kubernetes.io/docs/reference/generated/kubernetes-api/v1.17/#statefulsetspec-v1-apps" rel="nofollow noreferrer"><code>StatefulSet</code> with <code>podManagementPolicy:</code></a> which allows you to control the order they are created and then destroyed.</p>
