How to Keep Kubernetes Workloads Available During a Cluster Version Upgrade

A cluster upgrade can disrupt workloads when APIs are deprecated, node pools roll too quickly, or workloads lack capacity and disruption planning.

What to check

Review supported API versions, upgrade notes, replica placement, disruption budgets, storage compatibility, and recovery options. Test manifests and workloads in a representative environment.

Recommended next step

Upgrade in documented stages with workload health checks between them. Informatix Systems can plan Kubernetes operations and platform upgrades.
