Kubernetes operations, upgrades, and security in production
K8s in search: cluster lifecycle, version skew, hardening, upgrade windows, and day-2 that teams actually want to pay for. Cloud and hybrid context.
The operational debt problem
Searches are specific: upgrade order, CNI and CSI compatibility, and pod security. Platform teams also care about cost visibility per namespace and tenant isolation.
Frequently asked questions
How often should we upgrade our clusters?
Follow vendor support life cycles and a planned cadence, not an emergency when something goes end-of-life. The hidden cost of lagging is CVE debt and an inability to get vendor help quickly.
What is a realistic multi-cluster strategy for a mid-size company?
Usually separate prod and non-prod, with a clear promotion path and image policies—avoid duplicating a dozen one-off clusters that each become snowflakes with their own runbooks.
