<h2 id="setting-up-pod-disruption-budgets">Setting Up Pod Disruption Budgets</h2>
|
|
<p>Setting up a pod disruption budget is important due to erratic node shutdown possibility.
|
|
What could happen is that nodes that are hosting the applications start terminating, and our application becomes
|
|
unresponsive until the application is re-located to another node.
|
|
To avoid that situation, for the instances we need to configure pod disruption budget on our helm deployments.</p>
