Designing Kubernetes Topologies for Resilience, Scalability, and Operational Safety Across Cloud Providers
A small act of support goes a long way. You're helping me stay consistent and keep the content flowing.
Finally, a blog that doesn’t just repeat docs. The Rancher series actually helped me get a broken cluster back online.

You’re not just learning, you’re building smarter systems.
Stop waiting for schedules to debug CronJobs. Learn how to trigger them immediately, validate specs, and streamline testing in Kubernetes.
Helm upgrade failed due to Kubernetes managedFields conflict. Learn why spec looked fine, yet patching caused errors, and how to fix it.
Compare Kubernetes topologies across AWS EKS, Google GKE, and Azure AKS. Learn how to design resilient, production-grade clusters the right way.
Interact with Kubernetes subresources like `status` and `scale` using `kubectl` natively with the new `--subresource` flag, no more raw HTTP calls.
CVE-2025-1767 exposes root-level access on nodes via a deprecated volume plugin; Kubernetes 1.33 will disable it by default
Enhance Kubernetes pod scheduling with dynamic affinity using matchLabelKeys and mismatchLabelKeys for safer rollouts and tenant isolation.
Pods can now exclude tainted nodes during topology spread calculations, improving placement predictability.
Kubernetes 1.33 ensures PV reclaim policies are honored even if PVs are deleted before PVCs, preventing storage leaks across CSI and in-tree drivers.
A Kubernetes pod takes a fast async path, skipping blocking API calls handled in the background, showing the shift from sync to async preemption.
Kubernetes adds limited swap support for Burstable pods, offering memory flexibility on cgroupsv2 nodes without compromising workload stability.
Kubernetes now aligns memory-backed emptyDir volumes with pod memory limits for improved portability and consistency across node types.
Kubernetes wasn’t built from scratch. Learn how Google’s secret systems shaped its design, and why that origin still matters for developers today.
Use Pluto to identify deprecated or removed Kubernetes APIs in your manifests and Helm charts before upgrading, ensuring smooth and predictable cluster upgrade.
A new /statusz endpoint is coming to Kubernetes. Find out how it boosts debugging and observability without touching your metrics stack.
A critical kubelet bug exposes a DoS risk via the unauthenticated /checkpoint API. Learn how to detect, mitigate, and patch CVE-2025-0426.
Kubernetes v1.33 lets you configure container stop signals via PodSpec, no more rebuilding images just to change shutdown behavior.
Discover how Kubernetes v1.33 introduces a new /flagz endpoint in Kubelet for runtime introspection of component flags, debug like never before.
Kubernetes 1.33 speeds up recovery with a 1s initial delay and 60s max backoff for restarts, opt-in via feature gate for faster handling of failing containers.
Pods that grow with your workload? Discover how Kubernetes v1.33 lets you scale CPU and memory without a restart, and when it still might not be enough.
Kubernetes v1.33 finally enforces image pull secrets even for cached images, closing a 10-year-old loophole in multi-tenant cluster security.
Did you know you can recover deleted Kubernetes resources from etcd snapshots without downtime or cluster rollback? Most don’t, it’s surprisingly simple.
