Andrew Pruski is a Kubernetes slumlord:
The default time that it takes from a node being reported as not-ready to the pods being moved is 5 minutes.
This really isn’t a problem if you have multiple pods running under a single deployment. The pods on the healthy nodes will handle any requests made whilst the pod(s) on the downed node are waiting to be moved.
But what happens when you only have one pod in a deployment? Say, when you’re running SQL Server in Kubernetes? Five minutes really isn’t an acceptable time for your SQL instance to be offline.
Click through to see how to handle this scenario.
