How Kubernetes Pod Disruption Budgets Cause Node Drain Stalls
from DevOps Daily with Fexingo: CI/CD, Kubernetes, and Modern Software Operations Hosted by Fexingo
On this milestone 150th episode, Lucas and Luna dig into a Kubernetes failure mode that quietly grinds cluster upgrades to a halt: Pod Disruption Budgets. Using the story of a mid-sized fintech that got stuck mid-drain for six hours, they explain how PDBs interact with node drains, voluntary disruptions, and replica counts, and why your 'minAvailable: 2' can block a rolling upgrade even when nothing looks wrong. They walk through the warning signs, the kubectl commands that reveal the blockage, and practical fixes like ephemeral burst capacity and drain timeouts. Plus, a short note on why this show stays ad-free and how listener support keeps it that way. #Kubernetes #PodDisruptionBudgets #NodeDrain #DevOps #SRE #CloudNative #ClusterUpgrades #Kubectl #Fintech #Infrastructure #ReliabilityEngineering #TechOps #SoftwareOperations #FexingoBusiness #BusinessPodcast #TechPodcast #DevOpsDaily #K8sFailureModes Keep every episode free: buymeacoffee.com/fexingo
