Containers and Kubernetes, judged by what happens when a pod dies

Orchestration adds automatic recovery. It also adds new ways to fail. A Kubernetes cluster can restart a crashed container in seconds and still route traffic to a pod that isn't ready, starve a service of memory, or roll a bad version out to every replica before anyone notices.

Here we cover readiness and liveness probes, resource requests and limits, rolling update settings, pod disruption budgets, role-based access control, and the monitoring you want before a cluster carries customer traffic. We also ask the less exciting question of whether you need Kubernetes at all. For many small teams, a managed container service is the more reliable choice.

Articles assume you're running systems you're authorized to manage, and security examples stay defensive. The goal is a cluster that fails in ways you expected and recovers in ways you've tested.
