A new hero has emerged in the Kubernetes universe — the in-place vertical pod update feature. This revolutionary capability brings simplicity, agility, and increased availability to your updates.
In this article, we’ll embark on a delightful journey exploring the magic of in-place vertical pod updates, peppered with fun and practical YAML examples. So, fasten your helm belts, and let’s dive into the wonderful world of Kubernetes updates!
In-Place Vertical Pod Updates — Unleashing the Magic!

This incredible power allows you to update pods without the need for termination, ensuring that your applications remain unscathed and your users blissfully undisturbed. It’s like having Scarlet Witch warping reality while your applications continue to work their magic!
