Kubernetes & Platform
9 guidesPod lifecycle, traffic routing, resource behavior, and controller operations.
Kubernetes Foundations: Pods, Workloads, and Declarative State
Understand what the API stores, why controllers replace Pods, and how labels connect workloads without treating a cluster as a remote shell.
Kubernetes Foundations: Services, Configuration, and Least-Privilege Access
Connect replaceable Pods through stable Services and reason about configuration, credentials, namespaces, and workload API permissions.
Kubernetes Foundations: Objects, Controllers, and Reconciliation
Learn how desired state, API objects, and controller loops turn declarative manifests into running workloads.
Kubernetes Rollouts: Readiness, Health Checks, and Safe Deployments
Deployments are easy to start and hard to trust. Learn how readiness probes, rollout strategies, and traffic shaping keep Kubernetes services stable during real releases.
Kubernetes Requests, Limits, and Autoscaling: A Practical Capacity Model
Connect pod resource requests and limits to scheduling, throttling, eviction risk, and Horizontal Pod Autoscaler behavior.
Kubernetes Advanced Operations: Packet Paths, Rollouts, DNS, and Operators
Trace service traffic, prevent rollout 502s, debug CPU throttling and CoreDNS, and design conflict-safe controller reconciliation.
Kubernetes CronJobs: Timezones, Missed Starts, and Duplicate Work
Operate a scheduled report as a reconciled workload with explicit timezone, lateness limits, and application-level deduplication.
Kubernetes disruption budgets: protect capacity, not every failure
Understand eviction admission, readiness accounting, and why a drain can correctly refuse to proceed.
Kubernetes finalizers: deletion is a protocol, not a cleanup callback
Follow deletion timestamps and controller-owned finalizer removal without hiding leaked resources.
